"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).

from 2.5 percent (or 5.9 million people) to 2.0 percent (or 5.5 million people).
