Smokers can't and don't smell themselves. True for tobacco, cannabis, meth, or anything that is habitually smoked by someone. Their brains desensitize them to the odor.

I didn't realize this until I quit tobacco in my 20's and then went to the bar with my friends. Boy oh boy, I couldn't believe how bad I smelled the next day after being around tobacco smoke all night, and I realized that I had unknowingly smelled like that all the time before I quit.

And whether or not you realize it, there are stoners around you in daily life all the time. Only the slobs reek of bong water and dank bud.
