Even if some drug is addictive and dangerous, it does not need to be banned. Society should treat citizens as responsible adults, not as children in kindergarten requiring constant care. Yes, some people will fail to fight with addiction, unfortunately. I believe, eventually all drugs need to be legalized. But not all at once. It should be done very slowly. There are legitimate cases even for addictive recreational drugs. I think of this. Suppose I'm told I'm dying of cancer in 6 months. I could take painkillers for these 6 months and dying of boredom. But instead I'd prefer to stick to cocaine and have a lot of fun.
