Shoot, ive eaten canna butter made from a male that was awesome. Can also make a concentrate outa those leaves with alcohol or make some ice hash. Wont be no where near the same amount as what you would get off of female trim with popcorn buds and sugar leaves in the mix but reg leaves off of male or female plants seem to be about the same thc concentrate to me, just alot less finished product. If you have bucket loads of those leaves (stems work well as well) and dont mind alittle labor you deff will get something notable off those and should be good smoke if it was a good strain and ripe plants.
