In another, much smaller study, presented in 2004, researchers interviewed 12 gay men in New York with MRSA. Eleven of them had used crystal meth in the previous three months. Do 11 out of 12 gay men use crystal? Of course not. Eleven out of 12 gay men with MRSA did! Also, 11 of them shaved their body hair. No anal sex needed for transmission!
