Prevalence of Cannabis Use Among Young People in the European Union

(Prevalence of Cannabis Use Among Young People in the European Union) "The most prevalent illicit drug in all ESPAD countries is cannabis. On average, 16 % of the students have used cannabis at least once in their lifetime (Table 7a). The country with the highest prevalence of cannabis use was the Czech Republic (37 %). High prevalence rates (30% or more) were also reported in France, Liechtenstein and Monaco.

Changes In Cannabis Consumer Market Due To Changes In Dutch Coffee Shop Policies

(Changes In Cannabis Consumer Market Due To Changes In Dutch Coffee Shop Policies) "Considerable changes have taken place on the cannabis consumer market in the south of the Netherlands between 1 May (the start of the enforcement of the B- and I-criteria) and October-November 2012:
"• Drug tourists mostly disappeared.
"• The number of visits to coffee shops decreased drastically (Nijkamp & Bieleman, 2013).

Effects of State Medical Marijuana Laws (MMLs) on Youth Marijuana Use

(Effects of State Medical Marijuana Laws (MMLs) on Youth Marijuana Use) "We found no evidence of intermediate-term effects of passage of state MMLs on the prevalence or frequency of adolescent nonmedical marijuana use in the states evaluated, with 2 minor exceptions. From 2003 through 2009, adolescent lifetime prevalence of marijuana use and frequency of daily marijuana use decreased significantly in Montana, as compared with a more modest decrease in lifetime prevalence and an increase in daily frequency observed in Delaware (Ps = .03).

Youth Medical Marijuana Use and Unmet Health Needs

(Youth Medical Marijuana Use and Unmet Health Needs) "Of key importance in the findings are the unmet health needs of these youth. Health issues such as depression, insomnia, and anxiety were significant problems that interfered with these youths' ability to function at school, maintain relationships with family and friends, and feel that they could live a normal life. The level of distress associated with these health concerns, along with the lack of effective interventions by heath care providers and family members appeared to leave them with few alternatives.

Attitudes of US 12th Graders Toward Legalization of Marijuana, 2013

(Attitudes of US 12th Graders Toward Legalization of Marijuana, 2013)
"• Table 8-8 lists the proportions of 12th graders in 2013 who favor various legal consequences for marijuana use: making it entirely legal (42%), a minor violation like a parking ticket but not a crime (25%), or a crime (21%). The remaining 13% said they 'don’t know.' It is noteworthy just how variable attitudes about this contentious issue are.

Cannabis Use and Diet

(Cannabis Use and Diet) Marijuana use is associated with higher daily caloric intake. In the NHANES III and CARDIA study, heavy cannabis users had ;20% higher calorie intake than nonusers (25,26). The increase in calories was from higher intake of all macronutrients. Specifically, the frequency and amount of consumption of soda, cheese, salty snacks, pork, and alcohol was higher in cannabis users. Consistent with other studies, the quality of diets consumed by cannabis users was poor (27).

Impact of Medical Marijuana Laws (MMLs) on Cannabis Use by Youth

(Impact of Medical Marijuana Laws (MMLs) on Cannabis Use by Youth) "We replicated the findings of Wall et al. (2) that marijuana use was higher in states that have passed MMLs, and our analysis suggests this is unlikely to be a causal association. Our difference-in-differences estimates suggest little detectable effects of passing MMLs on marijuana use or perceived riskiness of use among adolescents or adults, which is consistent with some limited prior evidence on arrestees and emergency department patients (17).

Cannabis Consumption, THC Levels, Performance Impairment

(Cannabis Consumption, THC Levels, Performance Impairment) "It is difficult to establish a relationship between a person's THC blood or plasma concentration and performance impairing effects. Concentrations of parent drug and metabolite are very dependent on pattern of use as well as dose. THC concentrations typically peak during the act of smoking, while peak 11-OH THC concentrations occur approximately 9-23 minutes after the start of smoking. Concentrations of both analytes decline rapidly and are often < 5 ng/mL at 3 hours.

Motor Vehicle Accident Risk From Cannabis Use and Estimated Wait-Time Before Driving

(Motor Vehicle Accident Risk From Cannabis Use and Estimated Wait-Time Before Driving) "Cannabis use impairs cognitive, memory and psycho-motor performance in ways that may impair driving.10 Recent data suggest that approximately 5% of Canadian drivers/adults report driving after cannabis use in the past year.39 Large-scale epidemiological studies using different methodologies (e.g., retrospective epidemiological and case control studies) have found that cannabis use acutely increases the risk of motor vehicle accident (MVA) involvement and fatal
