What does meth smoke smell like?

I moved to a new building that I really love, except for an odor that periodically filters into my master-bathroom. It smells like my neighbors are burning something. The smell is not cigarettes, pot, incense, etc. Meth is the only drug I have no knowledge of the smell of it being smoked. If someone could please explain what meth does smell like when it is burning I would really appreciate it.

Meth smoke is odorless, only experienced users can detect the slight scent of it.

A sweet smell mixed with the smell of burning plastic. It could also be the smell of someone smoking crack. It could be just me, but I seem to reit tasting a bit like burnt marshmallows.

i have only done meth once but it smelled like the vitamin aisle at a drug store.

It depends on what kind of meth your smoking because I've had crank that gags me because of the iodine used in it, and its horrible and i cant smoke. Then other crank that taste alright usually because it was made with red phosphorus and you don't need that much iodine. I d think it depends on your taste buds. But i think it smells like a mild cat piss.
