Chemsex among gay men

We have just launch our new research report (and Exec Summary) on chemsex.

It uses existing survey data on drug use, 30 in-depth interviews with gay men, key informant interviews and focus groups to examine: the context of chemsex; the impact oof drugs on sex and the potential role of chemsex in HIV and STI risk behaviour.
