Meth explores the rising wave of crystal methamphetamine use within the gay population. Through the reflections of a dozen gay men, we learn of the drug's allure, its promise, and why its popularity is soaring. Some of the men in the film are current users, and they share their life with us while under the constant influence of "Tina." Other interviewees are former denizens of "Tina World," who have managed to crawl back from the depths to which their addictions brought them. Throughout, Meth is an unflinching look at the devastating effects of addiction to this very serious drug.
