I'd have to agree with gorgoroth's list for the most part, plus some more. Although the question is what exactly consistutes 'hard'? (No more input please, Tryptamite

) The amount you crave it, why you crave it (psych vs physical), the scene revolving around it, availability, stigma, law? Really anything can get the best of some people. And addictive tendencies and biochemistry varies heavily from person to person, but everyone knows that.
I'll just be really vague and unhelpful: high powered GABAnergic drugs, high powered CNS stimulants, high powered opioid analgesics, highly potent or dissociative hallucinogens, high powered...other psychoactive stuff...uh...but where does one draw the line and categorize 'high powered' for that matter?
The first drug I ever did (minus beer n cigs) was heroin, so I can't say there is any drug I promised myself I wouldn't do (actually it was quite the opposite), EXCEPT the ones I knew weren't going to do anything pleasant in the first place, so I wouldn't waste my time on them (the only drug I still use that is completely fucking useless: nicotine.

)
There, I tried to answer a really difficult and subjective question with the least amount of typing.
