In 2017, 7.6% of the Swiss population aged 15 to 64 said that they had already taken an illegal substance (excluding cannabis). In 2002, this figure was 3.2%. Considerably more men (9.9%) than women (5.2%) consume illegal drugs. 1.5% of the Swiss population (aged 15 to 64) took illegal drugs in the past 12 months.      

This indicator is part of the Monitoring System Addiction and NCD (MonAM) of the Federal Office of Public Health (FOPH).

The consumption of illegal substances such as heroin, cocaine, amphetamines, ecstasy and LSD can have various negative effects. For example, their use can lead to risky behaviour, have a negative effect on memory and mental health and lead to serious addiction and physical harm. In addition to the negative effects on the consumer themselves, people close to the addicted person are also often under enormous strain.

The indicator provides information about the extent of the consumption of illegal substances in the population and on groups at risk.

Definition

This indicator was calculated on the basis of data from the Swiss Health Survey.

It shows the percentage of 15 to 64 year-olds living in private households in the Swiss population, who have consumed illegal substances (excluding cannabis).

The indicator is based on the DURECONS* index from the Swiss Health Survey. It should be noted that the total sum of the individual substances (for lifetime prevalence) does not show the share of people in the population who have once taken an illegal substance. The reason for this is that there are people who indicate that they have taken more than one substance.
