Sexually transmitted infections (STIS) are spread more easily from:
- Anal sex without condoms
- Frequent partner change
- Longer sex sessions
Chems can prolong sex sessions, giving greater opportunity for infections to be passed on. There is also a risk of trauma - abrasions to your penis/anus from repeated friction -causing STIS including HIV and Hepatitis C to be passed more easily.
Some people are 'slamming' (injecting) drugs and getting infections either through sharing equipment or from increased risk taking. Slamming' also increases the risk of overdose and other drug-related harmful effects.
