They do contain enough THC to give you a buzz, from smoking 2 grams before I was buzzed for only 10-15 minutes and my mind was not very active so it felt like a very shitty buzz. Many people also get headaches from smoking the leaves. The leaves are also VERY bitter, you will probably puke if you take a huge bong rip(and it will leave your bong and resin with a disgusting taste). I have also failed at making cannabutter with mature males, they only seem to work for compost and pollen. I have never tried smoking the balls because of my allergies, and smoking balls is just wrong. Also, I have never tried eating male plants but I'll let somebody else experiment with that
If you're bored or seek revenge maybe you can plant the males in somebody's yard and watch the cops raid their house.
In your case I'd just kill them and chop them into tiny bits then flush them down the toilet, you'll be happy to see them go.
