Serious criminal records, because they sell drugs? Sounds like a circular argument: Drugs screw up your life, because they’re illegal and you’ll get busted and then have a criminal record, which will haunt you forever, and therefore, drugs should be illegal to deter people from falling into this exact trap. But wait - if the harm comes only from the illegality, then that isn’t a harm that is prevented by prohibition, it’s caused by prohibition.
Oh that was just the beginning if it. A lot of them had burglary (stealing other people’s stuff so they could pawn it and get money for dope), theft by check (kiting bad checks at grocery stores to buy dope), family violence (as a result if being high and getting into an argument with their wives and beating the crap out of them), possesion and possesion with intent to sell, criminal mischief (damaging other people’s property during altercations), DUIs and DWI’s (which caused damage to other people’s vehicles), among others if I were to look them back up again.
There’s a lot of fallout from drug use. The user usn’t the only victim. The only people that I’ve ever known that justified drug use were either casual drug users, addicts, or drug dealers.
