Which "International Law" makes the personal use of cannabis illegal. I genuinely have not got a clue what you are talking about when you post that.Quote:

I would imagine that, if the United Kingdom can reclassify the drug from Class B to Class C, therefore reducing any penalty for it's possession and use, then it can remove it from the list of proscribed drugs entirely.
If you have information to the contrary I would like to see it.
Similarly, if it is openly available in Holland, is it illegal - under this "International Law" you speak of. Any insight would be appreciated.

In 1961 the United Nations made it a violation of international law to legalize marijuana.
OTTAWA -- A Liberal MP says Canada will violate an international treaty if it moves ahead with plans to decriminalize pot.
Ajax-Pickering MP Dan McTeague said representatives of the United Nations Office on Drugs and Crime met with government officials last week to warn that Canada's proposed legislative changes would contravene a 1961 UN drug control convention.

You should not confuse "Decriminalise" with "Legalise". In Holland, marijuana has been decriminalised, not legalised. It is not a criminal offence to be in possession of a small amount, but is still not legal, like a parking fine, for instance.

You mention a Treaty (not law) which prevents signatory countries from legalizing cannabis.
I would make 2 points.
Firstly that does not actually answer the question of which "International Law" makes the personal use of cannabis illegal in the first place.
Secondly a treaty is not really a law (international or otherwise) now is it. It is a negotiated agreement.
Your answer is specious, not entirely unexpected.
Interesting, these acts and treaties. Apparently, under the British North America act, the federal government of Canada would not have the right to interfere in a provincial decision governing the control or legalization of marijuana or similar "problems of a personal or regional nature."
As I understand it, we are no longer using the BNA and have a mish mosh of so called charters governing human rights. Add to that the "not withstanding clause" and Who knows what falls under Provincial or national jurisdiction.
I'd compare this to the gay marriage issue I guess, although legal under Canadian law, It's still up to each province to adopt or reject these laws.
I've seen the opposite as well. There are employment and communications laws enacted in BC which are not recognized by Ottawa although they also have laws on the subject.
It just depends on any associated trade, commerce, or international laws, which the federal government still has (or percieves it has) the authority to police, tax, etc., that might be tied to any part of a Provincially registered business or it's employees.
An example of this is: Telephone workers in British Columbia are protected under Canadian federal employment laws. You cannot hire replacement workers or impose wage cuts or conditions without union approval and ratification.
Cable television workers are provincially regulated and have no protection under Canadian employment legislation. You can replace them at will.
Odd because the technical training period required for a certified CATV technician is about twice as long as a telephone technician.
No doubt this is a result of telephone/ rail treaties and such from 100 years ago.
It's just one of the quirks in our system.
If BC decided to legalize anything tomorrow, Ottawa would have a taxation plan in effect by the end of the week. It might be challenged, but in the meantime...
It could happen.
If you were to read my first post JP you would have seen that I was unsure, I stated that quite clearly.Quote:

Your answer is specious, not entirely unexpected.
However, here is another view, just for you.
The Obligations of the UK Government under the Single Convention on Narcotic Drugs 1961.
There is an 'urban myth' propagated by spinned-out Government Ministers, ignorant drug policy 'experts' and lazy journalists, that Britain's supposed 'obligations' under the Single Convention prevents the government from legalising cannabis (or other drugs).
In fact the Single Convention places no obligation on any signatory to make possession, production or distribution of any drug for personal use a criminal offense. This has always been accepted as at least a permissible interpretation by the United Nations itself, as the official commentary on the Convention makes clear. ('Commentary on the Single Convention on Narcotic Drugs', 1961, United Nations, New York, 1973.)
The working papers of the Shafer Commission contain a detailed discussion of this point, reaching the conclusion that: "although a country may decide that possession for personal use should be a punishable offense, there is nothing in the Convention which requires it to do so". (Marihuana: Signal of Misunderstanding: The Shafer Report, Appendix, Vol. 1,Technical Papers, p 533.)
The most authoritative interpretation is that of Professor Adolph Lande, who as Deputy Executive Secretary of the Plenipotentiary Conference, acted as chief draftsman of the Convention: "The terms 'possession' and 'purchase' used in the penal provisions of the Single Convention mean only possession and purchase for the purpose of illicit traffic. Consequently unauthorised possession and acquisition of narcotic drugs for personal consumption need not be treated under the Single Convention either as punishable offenses or as serious offenses". (A. Lande The International Drug Control System in Drug Use in America: Problem in Perspective, Appendix, Technical Papers, Vol. III, p 129.)
The correct interpretation of the penal provisions of the Single Convention is that they deal only with the production and supply of drugs; acts incidental to personal use are not within its scope. It follows that not only possession but cultivation and distribution are required to be punishable only insofar as they are related to commercial trafficking not personal consumption.
1. It is open to the Commission on Narcotic Drugs, acting on the recommendation of the World health Organisation, to delete cannabis from the schedules to the Convention.
2. Cannabis could be removed from the scope of control by an amendment to the Convention proposed by any party and discussed by a special conference called for the purpose by the Economic and Social Council of the United Nations. It was with this in mind that the Dutch delegate to the Council
(19th April 1978) proposed that the Convention should be amended "so as to enable each party to decide for itself the extent to which cannabis may be allowed for personal use".
3. Any party to the Convention may legally withdraw from it on six months notice. The commonly used argument that for Britain to do this would lead to a breakdown in the international system of control of opiates, or even prevent the UK from obtaining opiates for legitimate use is simply not true. Ireland is not a signatory and they suffer no inconvenience. The reality is the system of control is applied to every country in the world whether it has signed the Convention or not. The International Narcotics Control Board is specifically authorised to do this by Articles 12, 13, 14 and 21 of the Convention.
4. The Vienna Convention of 1969 introduced the procedure of 'selective denunciation', which provides that a country may unilaterally withdraw from part of a treaty to which it is a party on various grounds, including "error of fact" in which the treaty itself and "fundamental change of circumstances". (The relevance of these provisions is considered in: Lienward The International Law of Treaties and US Legalisation of Marijuana, Columbia J Transnet. Law 1971 10(2) 413.)
5. The prohibition on non-medical use of drugs does not extend to cannabis leaves, and the prohibition of cultivation of the cannabis plant does not extend to cultivation for any purpose which does not involve the separation of the flowering and fruiting tops, or the resin, from the rest of the plant. (A Lands The International Drug Control System in Drug Use in America: Problem in Perspective, Appendix, Technical Papers, Vol III, p 129.)
The interpretations here are disputed elsewhere. Another spin on this is to say, if it is illegal to grow it, and illegal to traffic it, and illegal to sell it, it stands to reason it must be illegal to be in possession of it. But who gives a fuck? This is a forum, not a court of law.

It is not called the butterfly effect, it is called the Chaos Theory!!
Chaos Theory: A Brief Introduction
--------------------------------------------------------------------------------
What exactly is chaos? Put simply, it is the idea that it is possible to get completely random results from normal equations. Chaos theory also covers the reverse: finding the order in what appears to be completely random data.
When was chaos first discovered? The first true experimenter in chaos was a meteorologist, named Edward Lorenz. In 1960, he was working on the problem of weather prediction. He had a computer set up, with a set of twelve equations to model the weather. It didn't predict the weather itself. However this computer program did theoretically predict what the weather might be.
One day in 1961, he wanted to see a particular sequence again. To save time, he started in the middle of the sequence, instead of the beginning. He entered the number off his printout and left to let it run.
When he came back an hour later, the sequence had evolved differently. Instead of the same pattern as before, it diverged from the pattern, ending up wildly different from the original. (See figure 1.) Eventually he figured out what happened. The computer stored the numbers to six decimal places in its memory. To save paper, he only had it print out three decimal places. In the original sequence, the number was .506127, and he had only typed the first three digits, .506.
By all conventional ideas of the time, it should have worked. He should have gotten a sequence very close to the original sequence. A scientist considers himself lucky if he can get measurements with accuracy to three decimal places. Surely the fourth and fifth, impossible to measure using reasonable methods, can't have a huge effect on the outcome of the experiment. Lorenz proved this idea wrong.
This effect came to be known as the butterfly effect. The amount of difference in the starting points of the two curves is so small that it is comparable to a butterfly flapping its wings.
The flapping of a single butterfly's wing today produces a tiny change in the state of the atmosphere. Over a period of time, what the atmosphere actually does diverges from what it would have done. So, in a month's time, a tornado that would have devastated the Indonesian coast doesn't happen. Or maybe one that wasn't going to happen, does. (Ian Stewart, Does God Play Dice? The Mathematics of Chaos, pg. 141)
This phenomenon, common to chaos theory, is also known as sensitive dependence on initial conditions. Just a small change in the initial conditions can drastically change the long-term behavior of a system. Such a small amount of difference in a measurement might be considered experimental noise, background noise, or an inaccuracy of the equipment. Such things are impossible to avoid in even the most isolated lab. With a starting number of 2, the final result can be entirely different from the same system with a starting value of 2.000001. It is simply impossible to achieve this level of accuracy - just try and measure something to the nearest millionth of an inch!
From this idea, Lorenz stated that it is impossible to predict the weather accurately. However, this discovery led Lorenz on to other aspects of what eventually came to be known as chaos theory.
Lorenz started to look for a simpler system that had sensitive dependence on initial conditions. His first discovery had twelve equations, and he wanted a much more simple version that still had this attribute. He took the equations for convection, and stripped them down, making them unrealistically simple. The system no longer had anything to do with convection, but it did have sensitive dependence on its initial conditions, and there were only three equations this time. Later, it was discovered that his equations precisely described a water wheel.
At the top, water drips steadily into containers hanging on the wheel's rim. Each container drips steadily from a small hole. If the stream of water is slow, the top containers never fill fast enough to overcome friction, but if the stream is faster, the weight starts to turn the wheel. The rotation might become continuous. Or if the stream is so fast that the heavy containers swing all the way around the bottom and up the other side, the wheel might then slow, stop, and reverse its rotation, turning first one way and then the other. (James Gleick, Chaos - Making a New Science, pg. 29)
The equations for this system also seemed to give rise to entirely random behavior. However, when he graphed it, a surprising thing happened. The output always stayed on a curve, a double spiral. There were only two kinds of order previously known: a steady state, in which the variables never change, and periodic behavior, in which the system goes into a loop, repeating itself indefinitely. Lorenz's equations were definitely ordered - they always followed a spiral. They never settled down to a single point, but since they never repeated the same thing, they weren't periodic either. He called the image he got when he graphed the equations the Lorenz attractor. (See figure 2)
In 1963, Lorenz published a paper describing what he had discovered. He included the unpredictability of the weather, and discussed the types of equations that caused this type of behavior. Unfortunately, the only journal he was able to publish in was a meteorological journal, because he was a meteorologist, not a mathematician or a physicist. As a result, Lorenz's discoveries weren't acknowledged until years later, when they were rediscovered by others. Lorenz had discovered something revolutionary; now he had to wait for someone to discover him.
Another system in which sensitive dependence on initial conditions is evident is the flip of a coin. There are two variables in a flipping coin: how soon it hits the ground, and how fast it is flipping. Theoretically, it should be possible to control these variables entirely and control how the coin will end up. In practice, it is impossible to control exactly how fast the coin flips and how high it flips. It is possible to put the variables into a certain range, but it is impossible to control it enough to know the final results of the coin toss.
A similar problem occurs in ecology, and the prediction of biological populations. The equation would be simple if population just rises indefinitely, but the effect of predators and a limited food supply make this equation incorrect. The simplest equation that takes this into account is the following:
next year's population = r * this year's population * (1 - this year's population)
In this equation, the population is a number between 0 and 1, where 1 represents the maximum possible population and 0 represents extinction. R is the growth rate. The question was, how does this parameter affect the equation? The obvious answer is that a high growth rate means that the population will settle down at a high population, while a low growth rate means that the population will settle down to a low number. This trend is true for some growth rates, but not for every one.
One biologist, Robert May, decided to see what would happen to the equation as the growth rate value changes. At low values of the growth rate, the population would settle down to a single number. For instance, if the growth rate value is 2.7, the population will settle down to .6292. As the growth rate increased, the final population would increase as well. Then, something weird happened. As soon as the growth rate passed 3, the line broke in two. Instead of settling down to a single population, it would jump between two different populations. It would be one value for one year, go to another value the next year, then repeat the cycle forever. Raising the growth rate a little more caused it to jump between four different values. As the parameter rose further, the line bifurcated (doubled) again. The bifurcations came faster and faster until suddenly, chaos appeared. Past a certain growth rate, it becomes impossible to predict the behavior of the equation. However, upon closer inspection, it is possible to see white strips. Looking closer at these strips reveals little windows of order, where the equation goes through the bifurcations again before returning to chaos. This self-similarity, the fact that the graph has an exact copy of itself hidden deep inside, came to be an important aspect of chaos.
An employee of IBM, Benoit Mandelbrot was a mathematician studying this self-similarity. One of the areas he was studying was cotton price fluctuations. No matter how the data on cotton prices was analyzed, the results did not fit the normal distribution. Mandelbrot eventually obtained all of the available data on cotton prices, dating back to 1900. When he analyzed the data with IBM's computers, he noticed an astonishing fact:
The numbers that produced aberrations from the point of view of normal distribution produced symmetry from the point of view of scaling. Each particular price change was random and unpredictable. But the sequence of changes was independent on scale: curves for daily price changes and monthly price changes matched perfectly. Incredibly, analyzed Mandelbrot's way, the degree of variation had remained constant over a tumultuous sixty-year period that saw two World Wars and a depression. (James Gleick, Chaos - Making a New Science, pg. 86)
Mandelbrot analyzed not only cotton prices, but many other phenomena as well. At one point, he was wondering about the length of a coastline. A map of a coastline will show many bays. However, measuring the length of a coastline off a map will miss minor bays that were too small to show on the map. Likewise, walking along the coastline misses microscopic bays in between grains of sand. No matter how much a coastline is magnified, there will be more bays visible if it is magnified more.
One mathematician, Helge von Koch, captured this idea in a mathematical construction called the Koch curve. To create a Koch curve, imagine an equilateral triangle. To the middle third of each side, add another equilateral triangle. Keep on adding new triangles to the middle part of each side, and the result is a Koch curve. (See figure 4) A magnification of the Koch curve looks exactly the same as the original. It is another self-similar figure.
The Koch curve brings up an interesting paradox. Each time new triangles are added to the figure, the length of the line gets longer. However, the inner area of the Koch curve remains less than the area of a circle drawn around the original triangle. Essentially, it is a line of infinite length surrounding a finite area.
To get around this difficulty, mathematicians invented fractal dimensions. Fractal comes from the word fractional. The fractal dimension of the Koch curve is somewhere around 1.26. A fractional dimension is impossible to conceive, but it does make sense. The Koch curve is rougher than a smooth curve or line, which has one dimension. Since it is rougher and more crinkly, it is better at taking up space. However, it's not as good at filling up space as a square with two dimensions is, since it doesn't really have any area. So it makes sense that the dimension of the Koch curve is somewhere in between the two.
Fractal has come to mean any image that displays the attribute of self-similarity. The bifurcation diagram of the population equation is fractal. The Lorenz Attractor is fractal. The Koch curve is fractal.
During this time, scientists found it very difficult to get work published about chaos. Since they had not yet shown the relevance to real-world situations, most scientists did not think the results of experiments in chaos were important. As a result, even though chaos is a mathematical phenomenon, most of the research into chaos was done by people in other areas, such as meteorology and ecology. The field of chaos sprouted up as a hobby for scientists working on problems that maybe had something to do with it.
Later, a scientist by the name of Feigenbaum was looking at the bifurcation diagram again. He was looking at how fast the bifurcations come. He discovered that they come at a constant rate. He calculated it as 4.669. In other words, he discovered the exact scale at which it was self-similar. Make the diagram 4.669 times smaller, and it looks like the next region of bifurcations. He decided to look at other equations to see if it was possible to determine a scaling factor for them as well. Much to his surprise, the scaling factor was exactly the same. Not only was this complicated equation displaying regularity, the regularity was exactly the same as a much simpler equation. He tried many other functions, and they all produced the same scaling factor, 4.669.
This was a revolutionary discovery. He had found that a whole class of mathematical functions behaved in the same, predictable way. This universality would help other scientists easily analyze chaotic equations. Universality gave scientists the first tools to analyze a chaotic system. Now they could use a simple equation to predict the outcome of a more complex equation.
Many scientists were exploring equations that created fractal equations. The most famous fractal image is also one of the most simple. It is known as the Mandelbrot set (pictures of the mandelbrot set). The equation is simple: z=z2+c. To see if a point is part of the Mandelbrot set, just take a complex number z. Square it, then add the original number. Square the result, then add the original number. Repeat that ad infinitum, and if the number keeps on going up to infinity, it is not part of the Mandelbrot set. If it stays down below a certain level, it is part of the Mandelbrot set. The Mandelbrot set is the innermost section of the picture, and each different shade of gray represents how far out that particular point is. One interesting feature of the Mandelbrot set is that the circular humps match up to the bifurcation graph. The Mandelbrot fractal has the same self-similarity seen in the other equations. In fact, zooming in deep enough on a Mandelbrot fractal will eventually reveal an exact replica of the Mandelbrot set, perfect in every detail.
Fractal structures have been noticed in many real-world areas, as well as in mathematician's minds. Blood vessels branching out further and further, the branches of a tree, the internal structure of the lungs, graphs of stock market data, and many other real-world systems all have something in common: they are all self-similar.
Scientists at UC Santa Cruz found chaos in a dripping water faucet. By recording a dripping faucet and recording the periods of time, they discovered that at a certain flow velocity, the dripping no longer occurred at even times. When they graphed the data, they found that the dripping did indeed follow a pattern.
The human heart also has a chaotic pattern. The time between beats does not remain constant; it depends on how much activity a person is doing, among other things. Under certain conditions, the heartbeat can speed up. Under different conditions, the heart beats erratically. It might even be called a chaotic heartbeat. The analysis of a heartbeat can help medical researchers find ways to put an abnormal heartbeat back into a steady state, instead of uncontrolled chaos.
Researchers discovered a simple set of three equations that graphed a fern. This started a new idea - perhaps DNA encodes not exactly where the leaves grow, but a formula that controls their distribution. DNA, even though it holds an amazing amount of data, could not hold all of the data necessary to determine where every cell of the human body goes. However, by using fractal formulas to control how the blood vessels branch out and the nerve fibers get created, DNA has more than enough information. It has even been speculated that the brain itself might be organized somehow according to the laws of chaos.
Chaos even has applications outside of science. Computer art has become more realistic through the use of chaos and fractals. Now, with a simple formula, a computer can create a beautiful, and realistic tree. Instead of following a regular pattern, the bark of a tree can be created according to a formula that almost, but not quite, repeats itself.
Music can be created using fractals as well. Using the Lorenz attractor, Diana S. Dabby, a graduate student in electrical engineering at the Massachusetts Institute of Technology, has created variations of musical themes. ("Bach to Chaos: Chaotic Variations on a Classical Theme", Science News, Dec. 24, 1994) By associating the musical notes of a piece of music like Bach's Prelude in C with the x coordinates of the Lorenz attractor, and running a computer program, she has created variations of the theme of the song. Most musicians who hear the new sounds believe that the variations are very musical and creative.
Chaos has already had a lasting effect on science, yet there is much still left to be discovered. Many scientists believe that twentieth century science will be known for only three theories: relativity, quantum mechanics, and chaos. Aspects of chaos show up everywhere around the world, from the currents of the ocean and the flow of blood through fractal blood vessels to the branches of trees and the effects of turbulence. Chaos has inescapably become part of modern science. As chaos changed from a little-known theory to a full science of its own, it has received widespread publicity. Chaos theory has changed the direction of science: in the eyes of the general public, physics is no longer simply the study of subatomic particles in a billion-dollar particle accelerator, but the study of chaotic systems and how they work.

man whoever thought all that up must have been REALLY F*****G STONED :D
That post was very informative and entertaining, Yogi.
I learned some stuff.
But I'm a bit confused still.
Who is leaving and what pics did JP post?
