Prevalence of Cocaine Use by Age

"The proportion of 15-64 year-olds who have used cocaine at least once has significantly increased three-fold in 15 years, from 1.2% in 1995 to 3.6% in 2010. It increased by a third between the last two Health Barometer surveys. Use in the previous year almost doubled between 2005 and 2010 among 15-64 year-olds, from 0.5% in 2005 to 0.9% in 2010 (Table 2.2), a statistically significant increase. First time use usually takes place at the average age of 23.1 years.
"The age bracket mostly affected by cocaine use is young adults, with use becoming less frequent with increasing age. The proportion of cocaine lifetime users is highest amongst 25-34 year-olds (7.7% of the total, 11.2% of men, 4.4% of women). Fewer members of older generations have used the product at least once during their lifetime.
"Similarly, use during the year primarily affects 15-24 year-olds (1.8% of the total, 2.6% of men, 1.0% of women) then decreases and becomes practically nil from the age of 55 onwards."
