Cannabis tea (aka weed tea, pot tea, ganja tea or a cannabis decoction) is a cannabis-infused drink prepared by brewing various parts of the cannabis plant in hot or cold water. Cannabis tea is commonly recognised as an alternative form of preparation and consumption of the cannabis plant, more popularly known as marijuana, pot, or weed. This plant has long been recognised as an herbal medicine employed by health professionals worldwide to ease symptoms of disease, as well as a psychoactive drug used recreationally and in spiritual traditions. Though less commonly practiced than popular methods like smoking or consuming edibles, drinking cannabis tea can produce comparable physical and mental therapeutic effects. Such effects are largely attributed to the THC content of the tea, levels of which are drastically dependent on individual preparation techniques involving volume, amount of cannabis, and boiling time. Also in common with these administration forms of cannabis is the heating component performed before usage. Due to the rather uncommon nature of this particular practice of cannabis consumption in modern times (in contrast to historical use), the research available on the composition of cannabis tea is limited and based broadly around what is known of cannabis as it exists botanically.
According to a recent study on cannabinoid concentration and stability in preparations of cannabis oil and tea, a boiling period of fifteen minutes was found to be sufficient in order to reach the highest concentrations of cannabinoids in tea solutions. However, preparation of cannabis oil in the study was found to ensure a higher stability of cannabinoids than that which was found in preparation of cannabis tea.
It is advisable to decarboxylate ones cannabis beforehand to ensure a sufficiently psychoactive tea. Using coconut milk instead of dairy milk is also an option. One can add spices such as cardamom, nutmeg, saffron, vanilla, almond and more. Let the tea simmer for 5-10 mins, longer if using non decarboxylated material.
Cannabis tea was used for centuries in folk medicine as it was thought to be a treatment for rheumatism, cystitis, and various urinary diseases.
