It smells terribly, exposes others to negative health effects without consent and is one of the biggest causes of littering. Simply put it is a major nuisance with no benefits apart from profits for the tobacco/drug industry and addicts getting their high.
Could probably extend that to anywhere around minors in general too.
So where would smokers go? They can’t smoke indoors except for their own home - what about work? Are they allowed to go to events or concerts? Can they eat at restaurants? Where can they smoke?
Go talk to a grandma who can’t quit. Tell her she can’t go to a park. Or outdoors anywhere there is the possibility of no people. “Go be alone Nana, no one wants you near them.”
Suppose you just want to pick in a minority and this one is socially acceptable. You’re making sweeping statements about a type of person who may be trying to escape but are tied by addicted. It’s not racism but the underpinnings of bullying are there. Let smokers have some place they can relax or else you will make militant smokers who feel the pressure of everyone around them but unable to do anything about it.
Stop finding new types of people to piss off with unwarranted subjugation.
On their own private property or designated smoking spots (which should be away from people and high-traffic pedestrian areas).
There should definitely be publicly funded measures to help people get rid of these addictions (ideally to no or very little charge). In the long run it’d save the public (and former smokers) a lot of health and money.
It takes a bit of effort to shake an addiction but especially with the right tools it’s very doable.
“Just be happy”
Get granny some nicotine pouches. She probably doesn’t want to smell like cigarettes either. In the same way you can get your THC without making your whole area smell like brocolli-diarrhea by using gummies and the like, the world would appreciate you finding other ways to ingest your drugs than to stink up the space we all have to share.
