Myself, I don't do any hard drugs, I don't smoke, I don't drink alcoholic beverages at all, I don't drink coffee. Not because of moral reasons but because I don't enjoy it. I'm even trying to lay off the soda and have plain bottled water instead. I therefore have to admit that I am not the most qualified person to make a statement in this regard. Anyhow.
I oppose forbidding drugs legally. I think that an adult should be allowed to consume any kind of substance he wants to in any amount he sees fit, whether it's water or cocaine. Of course it's bad for you, but so are many other things. If somebody forces himself into sleep withdrawal, he's not fit to drive a car as much as a guy under the influence of LSD. The legal implications and the consequences in terms of assurance coverage are already in place. As long as that person doesn't harm somebody else, he should be free to do to himself whatever he wants.
Nobody can stop you from drinking a bunch of poisonous chemical detergent. Nobody does that though, because you'd have to be pretty idiotic to do that. In my eyes, the same goes for drugs. It's your responsibility to keep yourself alive and healthy. Legalization of drugs doesn't mean you have to take them, it just means you won't be persecuted by the law because of it. If one damages himself with it, he has nobody to blame but himself. Although this may seem like an arrogant "let's weed out the weak"-sort of statement, if somebody ODs on a drug, it says something about that person's character, i.e. not being fit to make decisions for himself. I have little pity for people who expect empathy for their drug problems because their real issue is a flaw in character. Somebody with balance problems shouldn't walk a tightrope, somebody with addiction issues shouldn't start taking heroin. It really is as simple as that and everything else if just an excuse for lack of willpower. You always have a choice.
Right now, I could get up, leave the house, buy a pack of cigarettes around the corner and nobody has any right to stop me from doing so. If I want to buy a huge dildo to shove up my arse, I am free to purchase one. I might even produce both of these at home for myself if I knew how. Now if I were to do the same thing with mescaline, I'd be arrested. All of the above are recreational and only cause others harm when used inappropriately.
I will get neither of these three things because I don't have the desire to use them. But I generally enjoy having the possibility to do so very much. If I ruptured my intestines and die from internal bleeding because I've overdosed my dildo usage, it would be terribly embarrassing, but it's my own fault because I am an adult and therefore responsible for my actions. Same with any drug. When harm is inflicted on others, it's the responsibility of the legal system to stop me. If I want to ruin my body, they can't do jack shit, otherwise every McDonalds would have been closed by now.
In conclusion, I think that owning and using hard drugs should be permitted. Drugs contain their own punishment and people suffering from it deserve every bit of it because, again, they are responsible for their actions. Let them have it.
