My ejiice is menthol only, nearly odorless. As my cloud drifted over my bro-n-laws head I asked him if he could smell it, he replied “sorta sweet”.
I’ve vaped while a patient in the hospital. If the cloud evaporated before someone came in they didn’t know. I’ve vaped on no smoking or vaping tour buses blowing the cloud towards me floor..... nobody had a clue. Restaurants, towards the floor, no problem
