GMFA, the leading gay men’s health organisation, and Burrell Street Sexual Health Clinic, the largest and most comprehensive NHS sexual health service in London, are joining forces to give gay men advice to make their chems use safer. The number of gay men using drugs while having sex, particularly G, mephedrone and crystal meth, has increased in recent years. These drugs lower inhibitions, enhance sexual arousal and are mostly cheap and easy to get, often leading to sexual risk-taking. When misused or dosed incorrectly, these drugs can be harmful to gay men’s physical, sexual and mental health. This is why GMFA and Burrell Street are launching Safer Chems – a campaign and web resource to reduce the harms of chemsex.
