Clinical significance

Cannabis is a derivative of a plant which originates in Asia (Cannabis sativa). The active substance is delta-9-tetra-hydrocannabinol. It is presented in the form of either the leaves, a resin or an oil and can be smoked on its own or mixed with tobacco. Low doses lead to mild intoxication and higher doses can induce sensory hallucination. Dependence is largely psychological. It can be detected for 7 days in the urine of light users (1 to 2 cigarettes per week) and for 21 days in that of regular users (5 cigarettes per day). Abuse is signaled by the presence of metabolites in the urine. Passive inhalation and former use can be distinguished from current, active use on the basis of the level of tetra-hydro-cannabinol.
