In the early part of the last decade, methamphetamine use in the Castro in San Francisco was called “the second epidemic” because gay men were having unprotected sex while high. But new research from The Journal of Acquired Immune Deficiency Syndromes or JAIDS, shows meth use by San Francisco gay men has declined considerably. Why? Was it the public service campaign? Or a generational shift? And is it really declining or are people reluctant to tell the truth due to a stigma now? Marilyn Pittman talks with the lead author of the JAIDS study, Henry Raymond, of the SF Dept. of Public Health, and Matthew Bajko of the Bay Area Reporter. Airs 7pm Pacific Thursday March 7th.
