you will get baked as shit when you hit the vaporizer the first time. after consuming a large amount of munchies that would never go together(marshmallows, peanut butter, and triscuits) and he hit the vape and got sick and turned green, mostly due to the food. and it does have a bit of a smell, it is afterall the thc which gives off the weed smell anyways, but like the other guy said, its very faint, and will go away on its own, though a little spray never hurt anyone or any room correct?
