There is always a risk.... Unless you live in a state that allows you to grow for medicinal purposes. So the answer is YES~!! Today I was in my barn and 2 helicopters flew by really low which pisses me off ( because they are not supposed to do that if you have livestock and I have horses ) They were doing a grid. Looking for weed. Luckily I harvested mine yesterday. AGAIN....YES IT IS A RISK~!!
