Hi. I have been working out a lot in the past few months and sometimes I'll get a whiff of some weed sometimes stronger than others. Now there has never been any weed in the area of the house nor is smoking allowed in my house. It smells like unburnt weed. I have looked everywhere around where the smell is and can't find anything. A couple days ago I took a towel out of the dryer and used it to wipe sweat off of me and then I smelled the weed again. I didn't smell it before I wiped the sweat off of me so I smelled the towel and it reeked of weed. Can sweat smell like weed?
