The most widely-consumed drug in 2019 was cannabis, followed by stimulants such as cocaine or amphetamines. Heroin use remained "marginal", according to a new report published this week.
The Ministry of Health has published its annual RELIS report, which analyses illegal drug use and its effects at national level on a yearly basis.
According to the 2019 report, cannabis consumption has risen slightly since 2014, although its use among people aged 15-34 still lies beneath the European average. Consumption has also risen amongst the youngest members of that category since 2006. Drug commissioner Alain Origer said a particular increase had been observed amongst girls in that age group, while an overall increase of 27% had been reported in those aged 15 to 18.
Amongst the general population, the consumption of risky substances has dropped somewhat. Around 5 in 1,000 people aged 15 to 64 are thought to consume these drugs, compared to 9 in 1,000 back in the year 2000.
Cocaine and drug cocktails are gaining momentum in Luxembourg, said Origer, but the most popular of these more dangerous substances is still heroin. Origer pointed to changes in the way drugs are consumed, moving from injection to inhalation in many cases.
This new trend lowers the risk of overdose or transmission of disease, said Origer. In 2019, just three people reported HIV infections, compared to 21 in 2016. In the last year, six people have died as a result of an overdose, compared to 26 in 2000.
The average age of drug addicts has also risen over the past two decades, from 28 to 34. More people have sought treatment for cannabis addiction in the last 11 years, said Origer, which is partially attributed to the increase in THC percentages over the years - 11% in 2010, compared to around 19% now.
As for drug raids, the amount of cannabis seized by officers rose to 371 kg in 2019. Cannabis was by far the most confiscated drug in 2019, amounting to 70% of all seizures.
