Overall, no, generally I wouldn’t judge someone for smoking, or using drugs. I don’t know their personal circumstances.
However, if I had, or needed to have, some sort of relationship with them (acquaintance, friend, coworker, etc.), these things would impact how likely I am to spend time with them. There are some obvious clarifying questions:
- Does their behaviour affect me or anyone else? How?
- Am I comfortable being around them? Why/why not?
- Is their behaviour lawful?
- General considerations about what type of relationship I have with them, how often I see them, etc.
If their behaviour would negatively impact me, or was illegal, or made me uncomfortable, that would obviously impact my decision to spend time with them.
For example, for a romantic partner, it’s important to me that we have similar lifestyles, so smoking, drinking and drug use wouldn’t fit with that.
As a second example, I don’t like the smell of cigarette smoke or flavoured e-cigarettes, nor do I want the exposure to second-hand smoke or e-cigarette aerosols. I do have some family members that smoke (outside), and while I don’t want to be exposed to it, and will avoid being near them while they do it, they’re still my family, and I love them and don’t judge them for it obviously!
It definitely depends on my relationship with that person. It’s not that my opinion of them would change, rather just what our relationship would look like!
