There has been an emerging practice across the world when people use psychoactive or illegal drugs when having sex to feel less self-conscious, known as chemical sex or “chemsex.” A new report shows that people who practice chemsex are at high risk of severe health problems, and clinics might not be able to provide treatments for potential patients.

There has been a significant increase in the number of people practicing chemsex in the previous years, according to the editorial published in the British Medical Journal. It has also been found to be common in homosexual men.

The report shows that experts need to provide a necessary approach to stop "chemsex" as people under the influence of illegal drugs during sex potentially have high risk of having sexually transmitted diseases and developing mental health problems due to drug use.

The researchers said that people practicing chemsex tend to experience “losing days,” or being unable to sleep or eat for about 72 hours. Experts say that it could also severely harm their general health.

In chemsex, people tend to use drugs such as mephedrone, crystal meth, gamma-butyrolactone (GBL) and gamma-hydroxybutyrate (GHB), which are commonly referred as "party drugs." Users said that they use the drugs to feel less self-conscious during sex.

The report was guided by the London NHS Foundation Trust and was written by sexual health and substance abuse specialists from London. The findings come from the analyses of London-specific surveys of drug use during sex involving more than 181,000 homosexual men in Europe.

The researchers also reviewed how doctors and nurses would provide the necessary treatment support for the party drugs users. They have found that medical experts only have little information about chemsex.

“A greater integration between sexual health providers and drug clinics is necessary to guarantee the best support for people affected by chemsex.” Jamie Willis, co-author of the study, told IFL Science. The lack of information could highly influence medical personnel to give advice for people struggling from the impacts of using drugs for sex.

London has been found to be one of the places with a large number of people practicing chemsex cultures in Europe. However, other countries such as the U.S. and Australia reportedly have the similar trends, according to IFL Science.

According to the charity Antidote, between 2013 and 2014, about 64 per cent of drug users in London reported that they have used party drugs for sex.
