Look if you don’t smoke weed and he or she does, cool out. Weed isn’t a big deal.
Weed isn’t poisonous. It’s not addictive. And it’s only barely illegal. Well, it’s still very much illegal, but most cops will admit they don’t care.
If they seem lazy, it’s not the weed. Someone who is motivated will be motivated, and someone who isn’t won’t be. Weed is just something easy to blame.
If you smoke weed and they don’t but they have a big problem with it, sit down and talk with them, and if they won’t budge, decide if it’s worth quitting for them. If not, move on and find yourself someone who doesn’t care.
It’s just weed.
