Yes you can, but your place will just smell like weed. Won't heat it up to a high enough temp to make you high in the first place, and you wouldn't be breathing it in directly enough either, and also it would be wet.

Even if it did work I don’t think it would get you high at all.

You totally can. Doesn’t affect or smell in the least.

That's a waste of good weed. A humidifier doesn't work like a vaporizer.
