Green Dragon is a tincture made by leaching the buds, leaves, or stems of the cannabis plant in a high-proof alcohol. The THC dissolves into the alcohol resulting in a dark green or brown liquid. The liquid is very potent and is usually dropped under one's tongue or it can be mixed with a variety of foods. In strictest terms, Green Dragon can be classified as an alcoholic beverage, but its primary purpose is to deliver cannabis compounds to the user. It is usually not intended for consumption in amounts which would be typical for most distilled spirits, such as the 50 ml shot.

Baking or "drying" the dry buds and leaves prior to adding them to the alcohol in either method increases the potency of the resulting preparation. This drink will not be visible in a urine test for up to three hours, however then it will wear off causing a positive urine test. Green Dragon stays in a person's system for about 3-4 weeks maximum before a urine test can be passed successfully.
