Methamphetamine enters the brain and triggers a cascading release of dopamine, serotonin and norepinephrine. It is highly active in the mesolimbic reward pathways of the brain, inducing intense euphoria, with risk for addiction. To a lesser extent, methamphetamine acts as a dopaminergic and adrenergic reuptake inhibitor with high concentrations serving as a monoamine oxidase inhibitor. Users may become hypersexual or obsessed with a task, thought or activity. Withdrawal is characterized by excessive sleeping, eating, and major depression, often accompanied by anxiety and drug-craving.[2] Methamphetamine users may take sedatives such as benzodiazepines as a means of easing their "come down", anxiety or enable them to sleep.[3]
