i'll never do heroin and i swear by it.
just seeing those junkies staggering through the town centre every monday morning just makes me wonder why anyone would want to go through that.
I'm not being harsh on heroin addicts, it just seems almost impossible to have a casual heroin habit, i mean i'd hate to be in that sort of state and to be honest i've never met a heroin addict with a steady job, house, car, wife etc, and i don't think there's such a thing as using heroin in moderation. not from what I've seen and heard anyway.
also I would say LSD because it scares me to think what my mind would be like after, but after studying it it seems it can do a lot for a person, i may give it a go some day.
