The stench of alcohol and weed is the stench of failure
Everyone I knew who was heavily into that stuff ten years ago is either dead or whining about not having money for food and housing. They'd rather sit around and do drugs. They do nothing to improve their lives and cry about how the world is unfair and how things should be free.
It also doesn't help that when a newbie comes in smelling of that stuff at work it's pretty much guaranteed that they're only going to work for a month and then screw everyone over by quitting the company.
Then there's the people in shops and eateries. The loudest Karens who harass others usually reek of one or the other.
I thought alcohol and weed were supposed to calm a person down and improve them. If being a lazy, entitled, Karen who gives into their mental issues is at the end of that path then I refuse to take part in any of it.
