Let me start this off by defining some of what I think about substance control, and what should and should not be the case in the world.
First, I believe that people have the right to do what they want to themselves. A substance should only be banned if it could be shown that any use of that substance would be irredemably irresponsible. Personally I feel that cigarettes fall into this category, but good luck banning that.
Secondly, I believe that the the duty of the government is to carry out measures which are effective, not ones which aim at moral superiority. So if legalising something leads to a better situation in all respects, but the government disagrees with legalising that thing, then it should be legalised. If a ban does more harm than good, then that ban should be repealed immediately.
As a balence to my first point, while I believe that adults have the right to get as drunk and stoned as they like, children do not have this right. In fact, the government has a duty to stop them from going into excess, (too often). I consider the situation with alcohol almost ideal. It is against the law for children to drink. However, I don't think it was ever intended that no person under 18/21, (depending on locality), should ever take a sip of alcohol. With the law as it is, shops are restricted from selling bottles and bottles of alcohol to minors, since if they do they will be reported and their license revoked. However, (until very recently, and I don't consider it a positive trend), no one would report an off-license for selling a sixpack to a seventeen year old. Likewise, you can have a drink or two in a pub, if under age - but only as long as you are responsible, since otherwise the pub will ask you to leave and not serve you, rather than risk losing its license. In this way, positive drinking habits are taught.
Having said all of this clearly, it's a lot easier to make a decision on this topic. Is there evidence that cannabis has detrimental effects to the extent that any use is irredemably irresponsible? No. It is not addictive. It is not possible to overdose on, (arguments to the theoretical possibility of this are irrelevent to the legalisation argument - painkillers and water are both easier to overdose on). It has almost no toxicity. Contrary to what has been said, cannabis does have legitimate medical uses, (whether or not government appointed doctors say so is meaningless. How many years of Bush-administration 'science' will it take for people to get to grips with this?). If you think otherwise when you're old and arthritic, and all your prescribed medication makes you nausious and disorientated. Yes, pensioners with arthritis are the largest group of people who claim medical useage rights. But who knows, maybe they're just thrill seeking hooligans.
Links made between schizophrenia and cannabis deserve their own paragraph. BAD SCIENCE! Yes, there is a very strong corrolation between schizophrenia and cannabis use as a teenager. But, as any scientist worth his degree can tell you, (and hopefully anyone vaguely educated), a stasticial corrolation does not prove or imply a causative relation. Just stop and think - would you be suprised if latent schizoprenics often had heavy useage of a drug commonly used to relieve anxiety and stress? A corrolation is shown for all drugs - a quick Google comes up with
this one for cigarettes. No one is suggesting that nicotine causes psychosis, I see. This evidence does not give an argument for banning cannabis for everyone for always.
However, since we're dealing with people's minds and lives here, it's always best to be safe. Even ignoring that correlation, it is fairly obvious that any frequent substance use in people who's minds and brains are still developing is not clever. A small degree of short-term memory damage is observed in long-term users, for instance.
This is all very ironic, given the current laws. Someone pointed this out to me a couple of years ago, and it changed my ways of thinking immediately. It was this: It is easier for a teenager to get hold of an ounce of hash than of a bottle of wine. Pow. Why it didn't occur to me earlier, I don't know. But by making cannabis illegal, the government limits its own methods of control to arrests of dealers - hideously inefficient. Dealers sell indicriminately to children and adults alike, whereas with alcohol, the government has the power to revoke the licenses of people who they have endorsed to serve people. Thus they have far more control over the sale of alcohol than if it were illegal.
The reason that the police cannot eliminate the dealers is that they have the support of the people and that cannabis is already accepted in the culture. However, that money goes to people selling hard drugs and finances other crime. Given what I said earlier about practical law over moral, even if it is 'wrong' for adults to smoke cannabis, the government is obligated to legalise it if it results in more control and more moderate use. If cannabis is legalised and sale is licensed, then this is the situation which would occur:
People buy less from dealers, for good reasons:
1. A level of quality is certified
2. The cannabis is guaranteed not to have been laced or cut
3. The cannabis is given a definite strength. The government can regulate acceptible strengths.
4. The transaction takes place in a much safer environment.
Dealers stop selling cannabis since their market has declined.
Children do not have that easy source any more.
At the same time, licensed shops won't serve them for the same reasons they won't serve alcohol.
Happy ending.
I agree that cannabis can have detrimental effects, on children. However, the only solution to this is to take greater control over the sale of cannabis. The best way to do this is to legalise and regulate, for the reasons given above. Of course, it would help if the government held some discussions over the topic that weren't pathetically biased, and stopped trying to aim propaganda at children which is so alarmist that it cannot be taken seriously. Above 18 there is no good evidence for detrimental effects to the extent that cannabis warrents a ban. In fact, it promotes calmness and contemplation, and is an excellent stress reliever.

For God's sake, you drive stoned? Don't you notice that
slight p) reduction in relfexes which could get you and other people killed?
