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

Prevalence and Frequency of Cannabis Use Among Youth in Greece, by Gender

(Prevalence and Frequency of Cannabis Use Among Youth in Greece, by Gender) "More students have repeated cannabis use (3 times or more; 7.8%) than they have only used 1-2 times (5.6%). Boys repeated cannabis use in significantly higher proportions compared to girls (11.1% and 4.4%, respectively). Repeated cannabis use (as opposed to 1-2 times use) increases after the age of 16. Finally, students in Athens and Thessaloniki repeat cannabis use in significantly higher proportions compared to other areas (10.6%, 11.1%, and 5.4%, respectively) (Table 2.2)."

Feasibility of DRUID Approach and of 0.5g/L BAC Risk Threshold

(Feasibility of DRUID Approach and of 0.5g/L BAC Risk Threshold) "Any threshold discussion should address the question if the DRUID approach to determine risk threshold as equivalents to 0.5g/L alcohol is feasible. From a scientific point of view it can only be justified to accept the same risk for all psychoactive substances (including alcohol). From a political point of view the determination of risk thresholds as equivalents to 0.5g/L alcohol might be questionable, because a BAC of 0.5g/L is not a legal limit in all European countries.

Persons Entering Treatment for Cannabis Use in Hungary 2011

(Persons Entering Treatment for Cannabis Use in Hungary 2011) "In 2011 the number and proportion of clients entering treatment because of cannabis use did not change substantially as compared to the year before. A total number of 3,321 persons started treatment or joined some sort of indicated prevention programme (preventive-consulting service), 543 persons (16%) voluntarily and 2,985 persons (91%) as an alternative to criminal procedure. Among cannabis users 2,492 persons (81%) entered treatment for the first time in their lives.

Home Cannabis Cultivation

(Home Cannabis Cultivation) "A recent overview of the research and police data on cannabis cultivation in Belgium and The Netherlands (Decorte 2010), pointed to the fact that the small-scale home growers constitute an important segment of the Belgian cannabis market. These small-scale home growers are more and more working in a professional way. However, they are not necessarily profit-oriented. Reasons for this increase in small-scale growing of cannabis could be the dissatisfaction with the cannabis products sold in the Dutch coffee shops (Decorte 2010)."

Number of Medical Marijuana Users in Canada

(Number of Medical Marijuana Users in Canada) "Among those who used cannabis, 17.7% (representing about 420,000 Canadians or 1.6% of the Canadian population aged 15 years and older) reported doing so for medical purposes. Prevalence of use for medical purposes was similar between male and female cannabis users (17.3% versus 18.4%, respectively), while more than one in five (21.8%) cannabis users aged 25 years and older reported using it for medical purposes, representing 1.5% of all adults in this age group.
