Understanding Meth

Learn about meth addiction and substance use disorder

Methamphetamines, a Schedule II drug, are a far more potent class of an amphetamine drug that are sometimes prescribed to treat narcolepsy and ADHD under the trade name Desoxyn. More commonly methamphetamine is a street drug that stimulates the usage of the central nervous system and the brain in a similar fashion to speed. Methamphetamines are available in two forms. As a white powdered crystal-like substance, and large crystal chunks, leading to the name “crystal meth.” Meth is also known by other names such as “chalk,” “crank,” “glass,” “tweak,” “crystal,” and, “tina.”

Meth can be taken orally, snorted, injected, or smoked, all producing various levels of a euphoric high, “rush,” and intense alertness. Snorting or orally ingesting meth creates a high without the rush. Smoking crystal meth, which is a purer form of the illegal drug, produces a very intense high and rush lasting between 4-12 hours. Following usage, methamphetamine is rapidly absorbed into the bloodstream and distributed to most parts of the body, including the central nervous symptom, producing effects similar to that of other stimulants, such as cocaine. Methamphetamine crosses the blood-brain barrier with greater ease that other stimulants, creating a longer-lasting high and, conversely, higher damage to the body, including damage to the brain and CNS. Methamphetamines are some of the most addictive substances in the world with many meth addicts stating that they have become addicted to the illegal substance after one usage.

Methamphetamine is a synthetic chemical that is commonly manufactured in illegal, makeshift laboratories using ordinary and inexpensive materials. The materials used to manufacture methamphetamines are highly dangerous. Meth lab cooks use derivatives from over-the-counter amphetamines such as pseudoephedrine and increases their potency by adding chemicals such as battery acid, drain cleaner, anhydrous ammonia, lantern fuel and antifreeze. Many meth cooks die in explosions in their meth labs. The production of one pound of methamphetamines creates five pounds of toxic waste.

Methamphetamines are extremely addictive in part because the drugs hyper-stimulate the pleasure pathways of the brain. When the drug is discontinued, many meth addicts begin to experience anhedonia, or the inability to feel pleasure, which can lead to relapse. This dangerous cycle is what leads many meth addicts to experience brain damage and damage to vital organs as their addiction progresses.

Methamphetamine addiction is treatable with the right combination of therapies and withdrawal techniques.


Meth addiction statistics

Methamphetamine addiction is a growing problem in the United States and worldwide. The United Nations Office on Drugs and Crime estimated that each year, the worldwide production of amphetamine-like stimulants at nearly 500 metric tons each year, with over 24 methamphetamine abusers. In 2008, the US estimated that over 13 million individuals aged 12 and over have abused methamphetamine – 549,000 of these are regular abusers of methamphetamines. This number is increasing exponentially each year.

Causes and Risk Factors

Causes and risk factors for meth addiction

Addiction to methamphetamines is not caused by a single factor; researchers believe the addiction is a disease caused by many factors working together. Some of the most common causes include:

Genetics: Individuals who have a first-degree relative, such as a parent or sibling, who are addicted to a substance such as methamphetamines are at a higher risk for developing addictions later in life.

Biological: Certain individuals may be born with a defect in the pleasure/reward system of the brain, which can leave individuals being unable or under-able to feel pleasure. Meth has powerful effects on the pleasure center of the brain, which may be why certain individuals become addicted to meth.

Environmental: Individuals who grow up in chaotic home environments where addiction runs amok are at greater risk for developing addictions later in life. In addition, individuals who begin to abuse drugs at earlier ages are at a greater risk for addiction to more hardcore drugs.

Psychological: It’s been postulated that individuals who are suffering from addictions to substances such as methamphetamines are attempting to self-medicate the symptoms of an underlying mental illness.
