That's what that smell is! There's a house on our road a bit over 1/4 mile away, and sometimes I smell a faint skunkiness as we walk by. I know they grow pot there.the odor of the local pot harvesting(almost smells like skunk)
The house that sold last summer was owned by a retired couple in their 70s. He grew pot, actually asked us one time if we wanted any.

That made them laugh. No, he didn't, and they thought it funny that he had some.
