If cigarettes/beer weren't already so ingrained into our culture, they would probably be illegal too or it might be the other way round. But as far as I see it it's illegal cos, although a lot of stuff s bad for you, they don't want to allow more stuff that's gonna mess you up. Drugs like this cause more strain on NHS and also cause a less productive workforce (which means shitter economy) as they can cause schizophrenia and generally turn people into idiots, not to mention the side effect of laziness so making green legal wouldn't really make sense in alot of ways for the government (although no doubt it would in some). But at the end of the day, who really cares? Is it gonna stop you blazing? How many people even know the different classes of the drugs they take? We already do enough illegal stuff without even giving it a second thought so I think it should more be about the actual effects of the substance rather than the legality of it that encourages each person to decide either way, for themselves. People need to stop being pampered so much and learn to think for themselves, although morally, sometimes and learn to take the law with a pinch of salt.
