If you're a judgemental ass deep down, chances are you either always will be or you're going to have to be the one to change your mindset. I'm a judgmental bitch when it comes to certain things, I won't lie, but I do think recognizing it is key. I once dated a guy that said, "Ew seriously?? That's worse than smoking cigarettes!!" when I told him I smoked weed... told me it was a HUGE turn off and couldn't really come up with a good reason.
I think there's a stigma associated with the whole "pot head" thing that makes non-smokers assume we're all just a bunch of air headed lazy asses that sit around all day living off unemployment, masturbating while we smoke a bowl or something lol. I'm graduating this year with a BS in marketing and IT with a 3.2 GPA from a good university. I have 2 jobs and take my future seriously. And I smoke a lot. haha
