Some of the above comments strike me as ?.., well, I don't know what to say but let's start with patronising, insulting and ignorant. The characters that I have followed have indulged in "unsafe" sex ( itself a value judgement, perhaps), vendettas, murders, theft, embezzlement, etc etc. why do people suddenly get "precious" about the reality of drug taking as a way of recreational life? This is a (great) work of fiction and should be judged as such. Do we really want to copy the Catechism or create a new one?
ps I have never taken any illegal drug in my 60+ years, except for sharing a joint which left me crying for three hours. Does this mean we should have baNned the film "Trainspotting"?
