It's the flavored shit the dudes with douche flutes blow giant clouds with all day.

Not saying there aren't bullshit harmful weed ones, there definitely are. But again, they're probably the flavored bullshit made with low quality terpenes and shit. Just research your brands and sources. I'd bet the weed vape producers are probably more cognizant about what they make their shit with than the nicotine vape producers.
