Meet Jason: a college educated documentary film producer, cat parent of two, and one of San Francisco's top drug dealers.

After Jason's world falls apart in LA, he moves to Berkeley for a fresh start with his kid brother. Just one problem: his long-closeted Adderall addiction has exploded into an out-of-control crystal meth binge. Within weeks, Jason plunges into the sprawling ParTy n' 'Play subculture of the Bay Area's gay community. It is a wildly decadent scene of drugs, group sex, and criminals, and yet it is also filled with surprising characters, people who are continually subverting Jason's own presumptions of the stereotypical tweaker.

Soon Jason becomes a dealer on the pretense of researching this tweaker world for a project that will carry him, like a life raft, back to the shores of a normal life. But his friendly entrepreneurial spirit and trusting disposition disarm clients and rival dealers alike. The money begins to roll in as demand increases to frightening levels. Suddenly, Jason is in control of the entire crystal meth market for San Francisco's gay community, even as he finds himself nodding off behind the wheel of his car, or walking down the sidewalk. As friends and family work frantically to steer him towards recovery, Jason resists, chasing something else: a sleepless nirvana fueled by sex, drugs, and the Tweakerworld.

With painful honesty, Jason Yamas has crafted a landmark narrative that is not just a personal account of addiction, but a portrait of a vulnerable, largely undocumented community of people who, for many reasons, have been marginalized to the point of invisibility.
