But the whole 'hurt people hurt people' thing is very true, and giving them repeated free hits only does more damage to everyone in the long run.
Addicts miss good old (nice high) heroin, medical staff miss good old (easy to deal with) heroin, but we've gotten so good at keeping (relatively) low-harm heroin out, everyone ends up on this garbage nobody even likes. Addicts hate it (you have to stay standing or you pass out and wake up sick), it's rotting limbs off, and it's just gonna get worse.
