Smoking in particular is so baffling to me. A legal and lucrative business with no positive effects at all. At least with alcohol or drugs you can feel happier, calmer, more hyped, and so on, the only positive effect of it is literally caused by the lack of nicotine in your body. It's crazy how it's still legal, though I understand why. The fact they are status symbols of some sort is damaging our society for sure, as it's seen as a cool thing to consume drugs, cigarettes, alcohol and so on. I hate fat shaming with all my might, but the upside is that people are pushed into trying to not be overweight. The negative perception around overweight people is a huge counter to the phenomenon. This doesn't happen enough with the rest, where smoking or drinking every other day is considered "cool". And yes, I had my fair share of drunk nights. I'd personally limit such substances even more, outright banning cigarettes and possibly even limiting alcohol rather than legalizing more drugs. I know that people who want to self-destruct can always find other solutions to do so, but I don't see why it should be made cheap and easy, if not even socially cool. But I understand the reasoning behind the legalizing, too.
