Methamphetamine (meth) is a powerful and highly addictive stimulant that dramatically increases brain activity and energy levels. Often known as crystal meth, it causes an intense surge of dopamine, creating short-term euphoria—

but at the cost of long-term mental and physical health.

Over time, meth alters the brain’s chemistry, making it harder to feel pleasure without the drug. This cycle of intense highs and severe crashes fuels compulsive use and rapid addiction. Though a limited form of meth may be prescribed medically (Desoxyn), most street meth is illicitly produced and dangerously potent—often smoked, snorted, injected, or swallowed.
