Cannabinoid hyperemesis syndrome (CHS) is recurrent nausea, vomiting, and cramping abdominal pain that can occur due to prolonged, high-dose cannabis use. [4] [5]CHS is associated with frequent (weekly or more often), long-term (several months or longer) cannabis use; synthetic cannabinoids can also cause CHS.
The short-term effects of cannabis are caused by many chemical compounds in the cannabis plant, including 113 [clarification needed] different cannabinoids, such as tetrahydrocannabinol, and 120 terpenes, [1] which allow its drug to have various psychological and physiological effects on the human body.
Over time, the marijuana gateway hypothesis has been studied more and more. In one published study, the use of marijuana was shown not a reliable gateway cause of illicit drug use. [68] However, social factors and environment influence drug use and abuse, making the gateway effects of cannabis different for those in differing social circumstances.
This is a partial list of herbs and herbal treatments with known or suspected adverse effects, either alone or in interaction with other herbs or drugs. Non-inclusion of an herb in this list does not imply that it is free of adverse effects.
The earliest systematic studies of physiological effects of cannabis-derived chemical were conducted in the 1920's (see Fig. The number of publications about marijuana/cannabis). The level or research activity in this area remained relatively low and constant until 1966, when a 10-fold increase in publication activity occurred within 10 years.
Marihuana prensada ('pressed marijuana') is a cannabis-derived product widespread among the lower classes of South America, [189] especially from the 90s. Locally it is known as "paraguayo" or "paragua", since its main producer is Paraguay. [190] Marijuana is dried and mixed with binding agents that make it toxic and highly harmful to health. [191]
While the Waldos story is history among many in the marijuana subculture, other rumors about 420’s origins have popped up over the years. Some say 420 is police code among officers for someone ...
Most cannabis drug tests yield a positive result when the concentration of THC-COOH in urine exceeds 50 ng/mL. [10] Urine testing is an immunoassay based test on the principle of competitive binding. Drugs which may be present in the urine specimen compete against their respective drug conjugate for binding sites on their specific antibody.
