Gay 'chemsex' is fueling HIV epidemics in Europe, experts warn

Chemsex refers to the use of drugs such as crystal meth to enhance sexual arousal and performance. Experts say it's pervasive in some European cities.

A surge in "chemsex" parties, where people spend days getting high on drugs and having sex with scores of partners, is re-fueling epidemics of HIV among gay men in European towns and cities, doctors say.

Despite much higher risks of contracting the virus that causes AIDS, as well as other sexually transmitted infections (STIs), users search online "hook-up" apps like Grindr for tags such as "high and horny" or "party and play" to find others wanting drug-heightened and often anonymous and unprotected sex.

The result, AIDS experts say, is that in cities across Europe, HIV is spreading rapidly among men who have sex with men — leading to concentrated epidemics in hard-to-reach groups.

"Chemsex is very pervasive now — it's a growing phenomenon," said Rusi Jaspal, a professor of psychology and sexual health at De Montfort University in the British city of Leicester who has been studying the spread of HIV and the chemsex scene.

At a London conference hosted by the International Association of Providers of AIDS Care (IAPAC), the group's president Jose Zuniga, described chemsex as a "challenge of proportions we cannot fully comprehend at this time."

Chemsex is characterized by the use of drugs such as crystal meth, mephedrone and GHB, or gamma-hydroxybutyric acid, to enhance sexual arousal, performance and pleasure.

A subset of chemsex is known as "slamsex", where partygoers self-inject drugs rather than taking them as pills or via pipes.

The drugs "reduce inhibitions and increase feelings of horniness or lust," Jaspal said, and contribute to "a perfect storm" in groups with high HIV rates for the virus to spread.

In a small study published in 2014 of people attending HIV clinics in England and Wales, 30 percent of HIV-positive men surveyed reported chemsex in the previous year, and 10 percent said they'd engaged in slamsex.

HIGH-RISK BEHAVIOR

Ignacio Labayen de Inza, a chemsex specialist who works at several UK clinics and online as a counsellor for men seeking help, says "things have got much worse" since then.

"It's not just a UK thing," he told Reuters during the IAPAC conference. "It's in Amsterdam, Berlin, Munich, Rome, Kiev, Moscow, Helsinki — and in many of what people call 'gay destinations,' like (Spain's) Ibiza, Torremolinos, the Canary Islands."

A Spain-based study last year found that of almost 750 HIV-positive men surveyed, 60 percent reported having unprotected anal sex and 62 percent had been diagnosed with an STI. Rates of infections and high-risk sexual behavior were higher among the 30 percent who reported having engaged in chemsex or slamsex.

Globally, the fight against HIV and AIDS has made dramatic progress in the past decade. According to the UNAIDS agency, 1.7 million people were newly infected with HIV in 2018, a 16 percent drop since 2010, driven mostly by reducing HIV rates in Africa.

But progress is stalling and the epidemic is tightening its grip in key groups. UNAIDS says more then half of new HIV cases in 2018 were in minority or marginalized groups such as men who have sex with men, transgender people and sex workers.

The human immunodeficiency virus that causes AIDS can't be cured, but can be kept in check for decades with cocktails of highly effective antiviral medicines. It's partly this advance that is behind the high-risk practice of chemsex, said de Inza.

"People are not scared any more of HIV," he said. "Many people I see say they think 'it's only a matter of time anyway, so I might as well have some fun.'"

Shannon Hader, deputy director of UNAIDS, says the key to limiting chemsex and its consequences is to get the right protection messages and methods to those who need them.

Encouraging use of HIV prevention drugs known as PrEP, or pre-exposure prophylaxis, is one effective step, she said, and can give people who have chemsex some control over their health.

"In this epidemic, we always have to be looking for what's coming next that we're not addressing," she told Reuters. "And with PrEP, we need to ensure we're not missing people in the chemsex environment."
