Methamphetamine (Meth)

Methamphetamine is illegal, addictive, and dangerous. It is often manufactured as a white, bitter-tasting powder or pill or fragments that look like glass or bluish-white rocks. It can be injected, smoked, snorted, or taken orally.

Methamphetamine in Wisconsin

Northwest Wisconsin experienced a surge in methamphetamine use and addiction in the late 1990s and early 2000s. State laws enacted in the mid-2000s restricted access to substances used to produce methamphetamine in home labs. Yet, in recent years, Wisconsin has seen a new surge in methamphetamine use and addiction. Abuse of this drug has spread to the southern and eastern parts of the state. It is growing in popularity because it is less expensive and it has a longer euphoric effect than other illegal stimulants. Today, the majority of the methamphetamine available in Wisconsin is produced in Mexico and transported here by drug-trafficking organizations.

Methamphetamine affects your brain. Meth causes changes in the brain circuits that control reward, stress, decision-making, and impulse control, making it more and more difficult to stop using even when it is having negative effects on your life and health. Frequent use also can lead to tolerance and withdrawal, so you need more of the drug to feel normal. Additional effects of using meth can include anxiety and depression, chronic fatigue, paranoid or delusional thinking, and serious psychological issues.

Methamphetamine affects your body. Meth use increases heart rate, blood pressure, and risk of stroke. Other negative consequences of long-term meth use are extreme weight loss, severe dental problems, and skin sores caused by scratching. Meth use affects the levels of dopamine in your brain. Dopamine is a neurotransmitter. It affects, among other things, movement, motivation, emotions, and feelings of pleasure. Because meth causes a flood of dopamine to the brain, the natural supply gets depleted. Thus, activities that would increase pleasure may no longer do so. This can lead to depression.

Methamphetamine affects your self-control. Meth can cause aggression, violent behavior, and loss of contact with reality.

Methamphetamine affects more than the user. Meth use impacts the user's family and friends. Children found in meth labs may experience emotional, behavioral, and cognitive problems. The chemicals used to produce meth can cause fires and explosions, produce toxic vapors, and damage the environment.
