I'm not a great fan of the 'if life gives you lemons make lemonade' philosophy. It was a wretched experience for me and I was able to grow from it. It's not a good path and no one ever deserves it.
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.
