Dronabinol is synthetic tetrahydrocannabinol or THC, which is the active ingredient of marijuana. It is an FDA-approved cannabinoid and is prescribed as an appetite stimulant, primarily for AIDS, chemotherapy and gastric bypass patients. It was also FDA approved as an anti-nauseant, in order to better address the nausea experienced after chemotherapy treatments. The brand name is Marinol. Users seeking to use the drug recreationally will find the effects to be very different and much less potent than actually using the marijuana plant. This is because only THC is present in dronabinol, while the marijuana plant has many more cannabinoids and ingredients that will get the user high.
I took some dronabinol pills today that I stole from my grandma.
