I'm not qualified to advise anyone on how they'll react to a substance, but I find the stats for cocaine addiction interesting. Perhaps the stats include crack cocaine, which is meant to be highly addictive and is something I'll never try, but I don't know what the big fuss is about cocaine. I've tried it a few times, it makes you feel more confident but otherwise isn't much of a 'trip'. Perhaps people become dependent on that artificial confidence.
