" Around one in 25 adults (4.0%) aged 16 to 59 said they had taken a drug in the last month. This equates to around 1.3 million people. The proportion is similar to the previous year (4.3% in the 2015/16 CSEW) and is statistically significantly lower than those observed a decade ago in the 2006/07 survey (6.0%) and when CSEW measurements began in 1996 (6.7%) (Appendix Tables 1.03 and 1.04; Figure 1.5).

Estimated Prevalence of Last-Year Drug Use Among Young Adults in England and Wales: Proportion Of 16-24 Year Olds Who Report Using Selected Substances In The Previous Year (In Percent)
"The level of last year ecstasy use by adults aged 16 to 59 in the 2016/17 survey (1.3%, or around 439,000 people) was similar to the previous year (1.5%, or around 492,000 people). There have been small but statistically significant falls compared with a decade ago (1.8% in 2006/07) and the start of measurement by the survey in 1996 (1.7%). Generally, the proportion of 16 to 59 year olds using ecstasy in the last year has been relatively flat throughout the lifetime of the survey, fluctuating between one and two per cent since measurement began in 1996 (Figure 1.4).

"Between 2007 and 2012 in the set of the Portuguese population there was a general decrease in lifetime prevalence6 (any illicit drug from 12% to 9.5%) and recent use (any illicit drug from 3.7% to 2.7%), with the exception of ecstasy and LSD, whose lifetime prevalence remained the same and LSD use in last 12 months increased slightly.
Lifetime, last year and last month prevalence (per cent) of cannabis use in different age groups for men and women in Sweden, 2004-2012
"Two per cent of the men and 0.9 per cent of the women reported some type of illicit drug use in the past 30 days, corresponding to approximately 53,000 men and 24,000 women or a total of 77,000 people. Adding to this the 50,000 people who in the past 30 days had used prescription medicine without a doctor’s prescription, the total figure increases to 127,000 people. The population study indicates that the highest proportion of regular drug use is found among young men between the ages of 15 to 24, while the highest proportion among women is observed in the ages of 25 to 34.
"In 2013, an additional cross-sectional study of drug use was conducted in a nationally representative sample of the population in Sweden (Ramstedt, 2014). A total of 15,576 individuals (59.3% of the total sample) participated in the study and 10.5% reported that they had used an illicit drug or used some prescription medication in a non-prescribed way during the past 12 months. In this study, cocaine and amphetamines were the most common illicit substance reported after cannabis.
