occasionally when I get stoned i get a red rash on my chest and neck. It's not a raised rash, just skin pigmentation. It only happens to me when I smoke weed, but not everytime. I smoke weed everyday for the past 3 years and the rash has happened (so I know of) Atleast 20 times. But it's only when I smoke weed. Does this happen to anyone else?! I can't even explain it to people and tell them why I have a rash. "Oh it's Cuz I just smoked weed"
Probably an adverse reaction to something used in the weed those particular times... fertilizers... pest sprays... who knows
I've had a few rashes after smoking over the years...typically they appear the next morning around my crotch area, though...
