I don't think drugs are for the weak-minded, for the same reasons as Furore: Strength of mind only comes into it when someone becomes dependant on a drug, or if they don't let the drug become something they are controlled by.

I used to take cocaine when I was 16, because I thought it would help on a night out (it made me feel very alert and sober rather than drunk at the bar). I used to, and still occasionally take mushrooms and acid for creativity trips when writing songs or drawing, but I don't think anybody could class drugs as for the weak-minded, no.
