"Lifetime cocaine use increased in 2010/11 compared to 2006/7, but last-year use remained stable (Table 2.2.3). The proportion of adults who reported using cocaine (including crack) at some point in their lives increased from 5.3% in 2006/7 to 6.8% in 2010/11. The proportion of young adults who reported using cocaine in their lifetime also increased, from 8.2% in 2006/7 to 9.4% in 2010/11. As expected, more men (9.9%) reported using cocaine in their lifetime than women (3.8%).
"The proportion of adults who reported using cocaine in the last year remained reasonably stable at 1.7% in 2006/7 and 1.5% in 2010/11. The proportion of young adults who reported using cocaine in the last year did not vary significantly, being 3.1% in 2006/7 and 2.8% in 2010/11. The proportion of adults who reported using cocaine in the last month remained stable at 0.5%."
