context_page_description: The effects of cannabis are caused by chemical compounds in the cannabis plant, including 400 different cannabinoids such as tetrahydrocannabinol, 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 that the final net effect cannot reliably be foreseen.
  Acute effects while under the influence can include euphoria and anxiety. Although some assert that cannabidiol, another cannabinoid found in cannabis in varying amounts, may alleviate the adverse effects of THC that some users experience, little is known about CBD's effects on humans. The well-controlled studies with humans have a hard time showing that CBD can be distinguished from a placebo or that it has any systematic effect on the adverse effects of cannabis. When ingested orally, THC can produce stronger psychotropic effects than when inhaled.
