(COMMUNITY FORUM) You have to look in sub–Saharan Africa to find HIV transmission rates as high as those among gay men who use crystal meth. The teeth-twisting, face-chewing synthetic central-nervous-system stimulant is hugely addictive, cheaply made, and perfect for those who like a side of personal destruction with their euphoria. The full title for this forum is "Deconstructing Tina: Why Are We Dying for Crystal Meth?" Great question. Panelists include former users and someone from the Snohomish County Police Department.
