What is the prescription drug that contains THC

I would love to get prescribed to whatever its called for various reasons. First, and most importantly I could have THC in my system legally and avoid violating my probation..... Okay that is the only the only reason ha ha. But, I know that doctors prescribe it for sleeping disorders and I guess that I kind of have sleeping issues. I think that I could get an online prescription pretty easily, but I need to do some research. So what is the actually name of the drug??

There's currently two drugs, one is just synthetic THC I think, see marinol.com. The other is only legal in a few places, I think Europe and Canada. It's more like a marijuana extract. But if you had a prescription for one of these you could just smoke weed as well because you would test posistive regardless.
