Effects of cannabis

The short-term effects of cannabis are caused by many chemical compounds in the cannabis plant, including 113 different cannabinoids, such as tetrahydrocannabinol, and 120 terpenes, which allow its drug to have various psychological and physiological effects on the human body. Different plants of the genus Cannabis contain different and often unpredictable concentrations of THC and other cannabinoids and hundreds of other molecules that have a pharmacological effect, so the final net effect cannot reliably be foreseen.

Acute effects while under the influence can sometimes include euphoria or anxiety.
