variations of this thread have been posted multiple times but i have a few specific questions about it. 1. how is the smell? me and my roommate sometimes smoke 7-10 grams in a night. if we were to vape the equivolent of this with the mflb with a towel under the door, fan, sploof, blowing it out the window. how bad would it smell during and after the sesh in our dorm and out in the halls. and does it smell like burnt popcorn? 2. how efficiant is it? like i said me and my roommate can smoke alot in a smoke sesh how much weed aprox. would we need to get us to the same level as 7 grams.
