if you don't have the addiction gene/brain chemistry even doing notoriously addictive hard drugs is just different. I've done almost all the drugs, and enjoyed them, do them for more than an evening or a weekend and it is absolutely clear that 'this is bad for you, no one can sustain a life like this, you are NOT the exception and you should probably keep this shit in check.' It isn't subtle at all - like a giant neon flashing sign that says "Life is not supposed to feel this good and exciting there will be a price to pay if you do this too much".

I think the difference is people with addict brain do hard drugs and feel normal, or they think that it makes them feel how they think everyone else must feel inside their head.
