Read a potential LPT, for weed, don't let your landlord or boss know unless they are #420. It's legalized, but society still frowns down on it. Thoughts?

Depends on your lease agreement. If there's a no-smoking clause then your landlord has reason to be upset if you smoke inside the place. That's never stopped me, just be discrete and courteous to your neighbours (don't stink up the place).

Otherwise, it's none of their business. Even if it were illegal.
