Crystal meth significantly increases the risk of a number of other health problems, including HIV/AIDS, Hepatitis B and C, and other sexually transmitted diseases.

Crystal meth is especially ominous for gay men from several points of view with regard to HIV. First, because it increases sexual arousal, disinhibits behavior, reduces impulse control, and disrupts logical thinking, it tremendously increases the risk of unsafe sexual practices which expose the crystal user to HIV and other sexually transmitted infections. This results, as documented in numerous studies, in high rates of anal sex, low rates of condom use, multiple sex partners, sexual marathons, and anonymous sex, all of which increase risk of transmission.

For men who are already HIV positive, meth provides a dangerous form of "cognitive escapism." Over time many such men experience social isolation, reduced sexual stamina, reduced energy levels, reduced self esteem, and other medical complications. Meth initially almost magically neutralizes these factors giving a sense of energy, vitality, and social connection. The drug quickly hijacks this sense of well-being, however, leaving the user feeling alone and caught in a spiraling vortex of empty sex and ever increasing drug use.

HIV positive men who use meth are also at risk for developing increased resistance to their HIV medications. There are several theories about this phenomenon. Most significantly, many men who party for extended periods simply don’t take their medications, providing a window for the virus to mutate. Some make valiant attempts to stay on their medication schedule while others simply take periods of "planned nonadherence." Another theory for increased HIV drug resistance in men who use meth is that meth increases body metabolism, resulting in a “window” between doses in which the virus can mutate.

Men using meth who also take ritonavir (Norvir) should be aware that their blood levels of meth can quickly increase to toxic levels because these two drugs are metabolized by the same enzymatic system. Just as Norvir acts as a booster for other HIV medications, it can boost the amount of meth in the bloodstream with dangerous consequences.

Meth use causes risky sexual behavior that exposes the user to a number of other health concerns besides HIV. These include Hepatitis C, Hepatitis B, and other sexually transmitted diseases such as syphillus and gonorrhea. It is very important to know your status regarding these health concerns. Get tested for your health and that of your partners.
