The short-termeffects of cannabis are caused by many chemical compounds in the cannabis plant, including 113[clarification needed] different cannabinoids, such as tetrahydrocannabinol (THC), and 120 terpenes,[1] 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,[2][3] so the final net effect cannot reliably be foreseen.
Acute effects while under the influence can sometimes include euphoria or anxiety.[4][5] Although some assert that cannabidiol (CBD), another cannabinoid found in cannabis in varying amounts, may alleviate the adverse effects of THC that some users experience,[6] little is known about CBD's effects on humans.[7][8]Cannabinoid receptor antagonists have previously been tested as antidotes for cannabis intoxication with success, reducing or eliminating the physiological and psychological effects of intoxication.[9] Some of these products are currently in development as cannabis antidotes.
