To be clear, I hate seeing people sleep on the street. It's terrible, but they don't have good options.
What’s an unmentioned but relevant issue to me is how things like MDMA and ketamine (users are less harmed and harmful than with alcohol) are lumped in with hardcore opioid and meth abuse. There’s “hard”drugs and then there’s HARDdrugs.
I’d rather see the really hardcore stuff not even sold in specialized stores with the other stuff, but rather directly distributed through places similar to methadone clinics. They can give whoever wants the drug the full PR on how this substance very likely will get a grip on you and demolish your life. Clinics themselves are quite grim, making the whole atmosphere around recreational use less enticing. And you can put a higher age limit like 21 or even 24 on it.
