i remember that episode, it was funny as hell!!
But seriously, i was watching HGTV and they showed how you could take a plant and cut it about 4 to 5 inches above the ground, then cut a slit into the center of it about an inch. then you take another plant, say a clone for instance, and insert it into the slit, and tape it up with some cloth or something. then it will grow the plant which was inserrted. the people on the show said to keep it in the same species, but also stated it would probably work with different species.
the problem with this is, what produces the THC? i think it is the roots, so with my above mentioned method, you would have to use the root ball and base stem of a marijuana plant to produce the THC. now the kicker. you have to insert something which is edible or ingestible, if to try it at all. i mean you would not want to insert something, or cross breed something for that matter, which is not healthy or good to put into the human body.
sure, tobacco is good and bad, but nicotine is proven to be addictive. so you may want to use something more like strawberrys, or a fruit or vegetable to keep the health of your body in mind. dont get me wrong, i will put some fucked up shit in my body, but i know it is fucked up when i put it in there. i would be hesitant to put something into my body which i was unsure of altogether.
