Appetite Loss
The 'munchies' are real, and dronabinol is FDA-approved for AIDS-related wasting — but cancer-cachexia trials found no benefit.

What the research says
THC's ability to stimulate appetite is real, but the clinical evidence is narrower than the folklore. Dronabinol (synthetic THC) is genuinely FDA-approved for appetite loss and weight loss in AIDS wasting syndrome. In cancer cachexia, however, the trials did not hold up: a 2021 meta-analysis of 5 trials (934 patients) found no significant benefit of cannabinoids for appetite in cancer cachexia, and the largest phase III trial of dronabinol (243 patients) found no difference from placebo. The mechanism (CB1 receptor activation, changed taste perception) is real and well-understood — the puzzle is why it hasn't translated into measurable benefit in the populations most studied.
The honest caveats
The approved evidence is for synthetic THC in specific wasting conditions, not for 'I lost my appetite this week.' For cancer- or illness-related appetite loss, dronabinol is a legitimate option to raise with a doctor. For everyday appetite support, low-dose THC before meals is a common approach — but higher doses make the side effects worse without adding appetite.
Compounds to explore
These are the compounds — terpenes and cannabinoids — that the research connects to this condition. They are starting points for reading a COA or choosing a product, not prescriptions. Each has its own guide with more detail.
Cannabinoid THC The appetite-stimulating cannabinoid — dronabinol is FDA-approved for this in HIV/AIDS wasting. Terpene limonene Can brighten food's taste and smell for some. Cannabinoid d8-THC A pharmacologic review notes appetite effects similar to d9-THC at lower strength — a milder option worth knowing about.
