METH: Here's the statement in context: "No population has seen more damage from this drug than gay men.

It has only been recently that researchers have been able to connect the dots between crystal and an increase in HIV/AIDS cases. A recent study in California showed that 25% of occasional crystal users and 40% of chronic users were HIV positive."
