It's still observable science to state that alcohol or tobacco are on the whole more damaging drugs than heroin and pretty much most drugs. Millions in the UK are walking around with destroyed livers or are coughing up shit having clogged up their lungs with smoke. The habit will likely get them in the end. A regulated and controlled morphine/heroin would no doubt cause societal problems, but the systems currently in place are likely more problematic. Walk around a British downtown street at 2am in the morning and tell me that looks healthy. A person wacked on heroin is unlikely to smash your face in, but a person looking for cut heroin at black market prices is more likely to steal from your home as the market makes it expensive and cut down in quality. In terms of personal health, and if regulated well, I think heroin is likely to be a safer form of addiction than many others, either legal or illegal. I believe nothing should be illegal, but know that will result in some tragedy. However, people should have the choice. I would much rather smoke opium than get drunk and society would likely be more peaceful.
It's just common sense and none of the policies concerning drugs have anything to do with common sense. It is merely the arbitrary exercise of state coercion and control.
