Note that I was telling what the government does, not what is my opinion on this.

If I was steering the wheel, I’d just ban all drug consumption in public spaces, but allow non-destructive ones in personal spaces (your property), which includes tobacco and weed. I’d probably also limit the alcohol limit in drinks to something like 11%, so no absolut vodkas or smirnoffs as those tends to cause serious brain damage, which in return affects everyone around who have to deal with your vegetable state even when sober

Disclaimer: I’m from east europe and alcohol consumption is kinda out of control for most people (yes, most people according to my experience)
