The problem is , They themseleves may think good dude and leave you aloneWhen we had our fence replaced they not only recognized the plants, they commented on the "amazing smell" coming from the wall vent in my shop. So I gave them a tour, and about an ounce each. I doubt they will be ripping me off any time soon (not counting the cost of the fence), but if I need some warranty work they might fight over who gets to come over to do the work.
But its the friends who they smoke the weed with and tell where they got it from due to the quality of your good smoke , There by lies the problem.
