1. Inebriates may exhibit drunken comportment, showing staggering gait and neuromotor incoordination; their judgment may be impaired with slower or inappropriate responses to stimuli resulting, for example, in higher rates for motor vehicle accidents: more than half of all fatally injured drivers had positive blood alcohol levels (4; Table 25) and over 90% of all traffic offenses in Canada were alcohol-related, consisting mostly of driving while impaired offenses (4; Table 33). Similar disturbances of behavior may be exhibited by persons “high” on drugs.
2. The manufacture, trade, and consumption of psychoactive substances is regulated by national laws and regulations, and by international treaties: for example, the annual list of licit manufacture and trade of certain psychoactive drugs is regulated by the International Narcotics Control Board of the United Nations, and the health effects of alcohol, tobacco, and other drugs are closely monitored by the World Health Organization (annual).
