Selling drugs can and should in some cases be illegal though
This still doesn’t help. If you make weed illegal to sell but legal to consume, soon you’ll have poor people selling weed and rich folks buying. Guess who ends up in jail though?
I think government should sell all kinds of drug, even hard drugs to addicts. In that process identify these hard drug addicts and help them transition to a life without these drugs through rehabilitation. This will also help pull away the drug money from gangs.
