Nausea (general)

Nausea not caused by chemotherapy. The strong evidence is specific to chemotherapy — this is weaker ground.

Limited evidenceWeak evidence from fair-quality studies, or mixed findings.

What the evidence says

Extrapolated from the chemotherapy-induced nausea finding. Not separately established by NASEM for general nausea.

The substantial NASEM evidence for cannabinoid antiemetics is specifically about chemotherapy-induced nausea and vomiting. Nausea from other causes has not been established in the same way.

There is an important counter-risk. Long-term heavy cannabis use can cause cannabinoid hyperemesis syndrome — cyclical severe vomiting, often relieved temporarily by hot showers. Because cannabis normally treats nausea, people frequently respond to CHS by using more, which makes it worse. The only definitive treatment is stopping cannabis.

What to ask for

This is a starting point, not a prescription. Take it to a licensed dispensary and ask to see the batch certificate of analysis.

Cannabinoids

  • THC

    The main intoxicating compound in cannabis. It drives most of what people mean by "high," and it is also the cannabinoid behind most documented therapeutic effects.

Terpenes to look for

Commonly present in products people choose for this. Terpene effect claims are preclinical — this is a way to find a product again, not a promise about how it will feel.

  • Limonene

    Bright citrus, lemon and orange rind

  • Myrcene

    Earthy, musky, faintly sweet

Formats

  • Vape cartridgeOnset 1–10 min · lasts 2–4 h

    Concentrated cannabis oil in a battery-powered cartridge. Discreet, potent, and easy to over-do.

  • FlowerOnset 1–10 min · lasts 2–4 h

    Dried cannabis, smoked or dry-herb vaporised. Fast onset makes it the easiest format to titrate.

  • TinctureOnset 15–90 min · lasts 4–8 h

    Liquid extract dosed by dropper. The most precise way to titrate an oral dose in small increments.
