I go the other way. I want it all to be legal as long as everyone knows what they are getting into. If an adult wants to poison them self it's none of my business. As long as you arent hurting anyone but youself. Personally, I have never smoked, touched a drug, and only had 5 drinks in my life time.
I personally have no issue with people smoking them as long as they do it in moderation.
This is coming from someone who has a close friend that once went through 10 ciggarretes a day when we were both in college (this was like late 2016).
I was indifferent to ciggarretes being banned until i've noticed some of my close friends becoming completely addicted to them (a cousin of mine also had a bad smoking addiction). Now, if they ever do get banned, I have no regrets saying that's no loss for me.
But if people want to buy them then I'm not gonna stop them. I just hope they know what they're putting in their bodies at the end of the day.
