Shisha experimentation decrease in Parisian high school students

Paris sans tabac sounded the alarm in 2007, while more than a third of students in schools and colleges of Paris had experienced shisha, when a decade earlier the product was ignored by students. We assessed how this evolved consumption for the last 6 years. Methods : A PST surveys with anonymous questionnaire are conducted every year in February on a random cluster sample of 2 % of students in schools and colleges of Paris with the help of the Rectorat of the Academy of Paris. Results: 19 744, 12 to 19 years-old schoolchildren were interviewed in 2008-2013. The experimenters shisha rate increased from 24.8 % in 2008 to 34.7% in 2009, 36.2 % in 2010 to reach a peak of 42.4 % in 2011. This rate decreased recently to 41.1 % in 2012 and 38.2 % in 2013. The decline of the experiment is the most important among 12-15 year-old schoolchildren who are always particularly responsive to new modes. Experimentation shisha which was 16.8 % in 2008 to that age, increased to 25.5 % in 2011 then after a peak down to 19 % in 2013. In boys the rate of ever used increased from 37.6% in 2008 to reach a peak at 46 % in 2011 then decrease to 39.9 %, while among girls we observed a lower rate of experimentation than in boy and increased from 32.4% in 2008 to 38.7 % in 2011 and down to 36.0 % in 2013 after a peak of experimentation. Conclusions: shisha which appeared in the new century as an early experimental tool to smoke, no longer progressing and seems even regression in high school students in Paris.
