No, he's the one who injected 'roids into his sphincter but the thread is gone now.

OK sorry bud, we are having too much fun at your expense.

Two different types of plants don't just graft to eachother. They have to be in the same family at least, and even then grafting is not usually successful unless they are the same species. The "fruit salad" trees don't generally do too well, with one or more of the grafts failing within a year.

That being said, you may be able to get the gene responsible for THC into a virus or bacteria, and get that into another plant somehow. But if a laboratory is going to do that, they either have some kind of permit to carry out research on cannabis, or they don't mind operating illegally, either way, they have no reason to find an alternative method to produce THC.
