You're coughing because THC is an irritant to mucus membranes. That's not smoke you're inhaling, so don't worry; if it were, you'd be having the same problems as you did when you smoked joints or blunts.

Those vapors may make you cough a bit, but they are far from smoke, which is essentially poison with THC mixed in.

Peace.
dannyboy420 Reviewed by dannyboy420 on . why does vapor make me cough? I have a box vaporizer, the VaporTower. I'm not sure if what I'm inhaling is actually vapor, or a mix of vapor and smoke, or just smoke. I know I get a lot of air along with the smoke/vapor. The hits seem to reach pretty deep in the lungs because I cough a lot, even more than I do from smoking. The spent weed isn't charred, it's just brownish green, so I guess I'm not burning it... and my throat is never sore after vaping, as it is after smoking. But it does seem to really choke me up.
