Meth is a dangerous drug on its own, but when it’s combined with other substances the potential risks increase. According to research by the U.S. National Library of Medicine (NLM), polysubstance use involving meth can lead to unsafe behaviors among people that belong to a high-risk group for sexually transmitted diseases. In 2009, the NLM surveyed 341 HIV-positive men and found that 65 percent engaged in unsafe, unprotected sex when under the influence of meth combined with another substance.
Partygoers made polysubstance use involving meth more common. When people are at night clubs or raves, they’ll typically combine any drugs available and other people may combine drugs as they become more intoxicated. Men, in particular, may combine meth with prescription medication that helps with sexual performance, like Viagra, because meth may cause erectile dysfunction.
