about 3-4 weeks ago i got a 4gram bud of nice grass , however it was a small bit damp but still nice to smoke. i smoked a bit and put the rest in a baggy and just left it in my room. but now (3-4 weeks later) a small film a mold has formed around the bud , doesnt smell bad or anything and i still wanna smoke it. but will the mold do harm or kill me or something and is it safe to smoke ?
