- Alcohol, tobacco and cannabis use among ninth grad...
First results of the EnCLASS survey among 2 000 ninth grade students.
In the first quarter of 2021, 1 972 fourth year students ("troisième" -grade 3 in France- would be the equivalent of secondary school in the UK or grade 9 of Junior High School in the United States) responded to a specific issue of the national adolescent health and substance use survey (EnCLASS) in middle and high schools.
The survey asked adolescents about their initiation to tobacco, alcohol and cannabis and, using new questions, about heavy episodic drinking, problematic cannabis use, methods of acquiring tobacco and alcohol, introduction to nitrous oxide and gambling practices.
