Drug Use Comparisons Between EU and US
"On average, 7% of the ESPAD students stated that they had used marijuana or hashish during the past 30 days. As a proportion of the group reporting lifetime use, this corresponds to roughly four in ten. The highest rates of past-30-days cannabis use are found in the two neighbouring countries of France and Monaco (24% and 21%, respectively), followed by the United States (not an ESPAD country) (18 %) and the Czech Republic and Spain (not an ESPAD country) (15% each). In these top countries, about 10% of all students had used cannabis at an average frequency roughly corresponding to at least once a week during the period in question (3–5 times or more in the past 30 days). This proportion is considerably larger than the average for all ESPAD countries (4%)."
