Cigarettes came into the Western world at a much different time on our history. If the English Government, AT THAT TIME, had been aware of its long term deleterious effects, it might have taken steps to ban them. I deliberately say might, because at the time cigarettes were introduced into Western society, the attitude was very different to the one that exists in our modern society, and Its long term deleterious effects were not known.

The same can't be said for marijuana, which has been shown to impair judgement, which I have witnessed first hand.

In regards to amphetamines, there is no way any sensible person could justify the usage of some forms of amphetamines without a prescription. But I am not conversant with all forms of amphetamines, so I can't give an opinion on all types.
