Background/ introduction
Recreational drug (RD) use is increasing in men who have sex with men (MSM) and increases sexual risk taking behaviour and possibly increasing attendances for PEPSE.

Aim(s)/ objectives
To identify Club drug use during PEPSE attendances in MSM in 2013/4 compared to 2015. 

Methods
Review PEPSE (MSM) attendance during two 4-month periods: November 2013 to February 2014 and March 2015 to June 2015.

Results
152 MSM attended for PEPSE: 51 in 2013/4 and 101 in 2015. The median age was 31(18-79) years. Documentation of Club drug use during PEPSE episode increased significantly from 27/51(53%) in 2013/14 to 100/101(99%) during 2015 (p<0.001). Club drug use during PEPSE episode increased significantly from 9/51(18%) in 2013/4 to 41/101(41%) in 2015 (p<0.005). There were no significant changes in the Club drugs being used: gamma-Butyrolactone(GBL), Mephedrone and Crystal Meth being the most frequent reported. 

Discussion/ conclusion
Episodes of unsafe sex leading to access of PEPSE appear to be more associated with Club drug use in 2015 than in 2013/4 and our documentation of this has improved. Identification of Club drug use in MSM is an important harm intervention.

In 2015, MSM accessing PEPSE is significantly more associated with club drug use than 2013/2014.
