Meth and skin picking: Formication and excoriation disorder

Published November 7, 2024 · 6 min read · Updated April 2026

Reviewed for accuracy by licensed clinical professionals.

Meth-related skin picking (excoriation) is one of the most visible signs of chronic methamphetamine use and results from both neurological and psychological mechanisms.

Why it happens

Formication: the tactile hallucination of bugs crawling under the skin. Dopamine dysregulation producing compulsive repetitive behaviors. Dry skin from dehydration. Slowed wound healing from malnutrition and immune suppression.

The damage

Open sores that become infected. Scarring from repeated picking. Cellulitis and abscess formation. Social stigma from visible wounds.

Treatment

Cessation stops the formication and compulsive behavior. Wound care for existing lesions. Antipsychotic medication for persistent hallucinations. CBT for compulsive picking behaviors. Skin improvement is one of the most visible early recovery changes.
