[kimchibanana]

i just made a few vaporizers with lightbulbs and i have a drug test coming up so i cant smoke gunja. how can i test if it works can i use tabacco and when i do smoke weed does it give off a scent besides regular weed smell?

Never smoked out of one, but it supposivly leaves no smell. You smoke the vapor, not the smoke. So I think it smells more like steam than smoke. Thats why vaporizers are so good, no smell and better for your lungs
