Margaret Haney, PhD, Associate Professor of Clinical Neuroscience at Columbia University, et. al, in their Aug. 15, 2007 study titled "Dronabinol and Marijuana in HIV-Positive Marijuana Smokers: Caloric Intake, Mood, and Sleep," published in the Journal of Acquired Immune Deficiency Syndromes, stated:

“As compared with placebo, marijuana and dronabinol [a synthetic pill form of THC] dose dependently increased daily caloric intake and body weight in HIV-positive marijuana smokers… Effects of marijuana and dronabinol were comparable, except that only marijuana (3.9% THC) improved ratings of sleep.

Conclusions: These data suggest that for HIV-positive marijuana smokers, both dronabinol (at doses 8 times current recommendations) and marijuana were well tolerated and produced substantial and comparable increases in food intake.”
