Cannabis tea is a very common way of consuming cannabis orally. Tea is relatively easy to make. There is no need for additional specialised equipment. Cannabis tea does not look like cannabis, nor does it produce smoke or vapor. Therefore, it allows the user to consume it in public (e.g. at work, family visit) without drawing much unwanted attention.
Studies have shown that an average cup of cannabis tea contains about 5 times more THC-acid than THC. The reason is that the temperature of boiling water is not as high as the temperature of cannabis when vaporized or smoked. Contrary to popular beliefs, the concentration of THC and CBD in fresh or dried cannabis plants is very low. Instead, cannabis mostly contains cannabinoid acids. When sufficient heat is applied to the plant, THC-acid will convert into THC, and CBD-acid will convert into CBD.
Due to the high amounts of acidic cannabinoids and low amounts of converted cannabinoids, it is likely that cannabis tea works in a different way. However, at this point it is not clear what the effects are exactly, as this has never been tested.
