"Tweaker" is a slang term for a person who compulsively uses stimulant drugs, most commonly methamphetamine. The name derives from the "tweaking" phase of addiction, characterized by intense paranoia, repetitive behaviors, and prolonged sleep deprivation. Physically, users often display dilated pupils, rapid speech, and skin sores, while their mental state can shift rapidly from extreme euphoria to irritability or hallucinations. #tweaker #usa #newyork | Teddy Young | Facebook
