I have a bit of a theory that vaping flower gives the lungs some protection from the carcinogenic shit put off by wildfire smoke and other air pollution. Cuz you know, if the plant itself gives you protection from itself for smoking it, that means vaporizing it puts you one step ahead.Right now the air quality in Oregon (and California and Washington) sucks. No, I mean really sux! This article from San Francisco about sums up the situation. NYT article on smoke in SF.
But you know, if you cultivate marijuana, for example the regulation four plants we are allowed here in Oregon, it is very likely that like me you have in your possession one or more very robust charcoal filters and powerful fans to run air through them in order to scrub odors from a favorite plant as it blooms. That, along with a decent HEPA filter can make the air indoors a bit of alright. So, as I always tell people: cultivating weed is good for your health!
