Meth Abuse Causes, Addiction Signs, Symptoms & Side Effects

Methamphetamines (more commonly known by their street name, “meth,” “crystal meth,” and “crank”) is a powerful and addictive stimulant that can be smoked, snorted, eaten, or injected. Due to the psychoactive properties, false confidence, and sense of happiness, people who try methamphetamine quickly develop a desire to continue using. Some users state that they were hooked on meth after they try it once. While initially pleasurable, methamphetamine can destroy a person’s life by burning up the body’s resources and leaving the user with a dependence that is only relieved by using more of the drug.

Methamphetamine is the child of a drug class called amphetamines, both stimulants that can provide users with increased energy, intense desire to chat, and an overall sense of happiness. However, methamphetamines are different than amphetamines because much higher amounts of methamphetamines are able to reach the brain which increases the potency. Meth also gives users a longer and more sustained high which leads to damage to the central nervous system.

Medically, methamphetamine is a Schedule II stimulant with a high potential for abuse. Medical methamphetamine is used to treat narcolepsy and ADHD. Medical methamphetamine is prescribed at a far lower dose than the street version.

Illegal or street methamphetamine is often produced in makeshift laboratories by using over-the-counter, readily-available inexpensive materials. Over-the-counter cold remedies are usually used as a base and are then combined with chemicals like battery acid, drain cleaner, ammonia, and antifreeze. These chemicals are particularly dangerous and many who manufacture methamphetamines are burned or killed during production.

Like cocaine, methamphetamines are produced in two forms: a white powder or clear chunks of rocks. The rock form, crystal meth, is the most pure and potent form of methamphetamine. Crystal meth is commonly used as a “club drug” at raves and nightclubs and is often called “glass” or “ice.” Methamphetamines are often used in a binge and crash manner. This cycle can cause the user to be up for days smoking, snorting, or injecting the drug before crashing from the euphoric feelings. By the time the methamphetamine binge is over, the person has not eaten or slept in days.

The euphoric high experienced by methamphetamine users is caused by a surge of dopamine released into the brain. Over time methamphetamine use destroys dopamine receptors within the brain. This means that a chronic long-term methamphetamine user will not be able to feel pleasure without the use of methamphetamine. Research suggests that these pleasure centers can heal over time, however, the damage to the cognitive abilities of the user may be permanent.

Statistics

Worldwide methamphetamine abuse is becoming an increasingly devastating epidemic. It’s estimated that there are 26 million methamphetamine addicts worldwide. Methamphetamines are now considered to be the world’s most abused drug. This is reflected in current number of methamphetamine addicts in United States, which are estimated to be approximately 1.4 million individuals.

Causes of Methamphetamine addiction

People try illegal drugs for a number of reasons, mostly involving being dissatisfied with their lives. Other reasons people abuse drugs include fitting in with peers and friends, escaping an unpleasant situation, relief from boredom, to rebel from authority, and to experiment. While methamphetamine use is often used to “solve” a problem, the drug abuse and consequences become the problem.

Genetic: research has shown that certain individuals have a genetic predisposition to develop a substance abuse problem or addiction. This is especially true for people who have a first-degree relative, such as a parent or sibling, who are addicted to a substance of abuse.

Biological: some researchers have proposed that methamphetamine abuse may be the result of lower levels of dopamine in the brain. Dopamine is a neurotransmitter that has a large effect on the pleasure feelings we receive from seeing our children or eating a great meal. This biological makeup could make people who abuse methamphetamines desire the euphoric feelings caused by increased levels of dopamine released by methamphetamine use.

Psychological: as many mental illnesses and other conditions can cause a decrease in feelings of happiness, many turn to substance abuse as a means to control their symptoms. In addition, methamphetamine, like other drugs of abuse, leads to the disruption of normal levels of dopamine in the brain, so that over time a methamphetamine user is unable to feel pleasure without using meth.

Environmental: individuals who grow up in in a chaotic home where parents do not show love and affection are more likely to develop a substance abuse problem. Also, children who are exposed to parents who have an addiction to substances such as meth, learn that abusing substances is the proper way to handle stress. In addition, a parent modeling substance abuse normalizes substance abuse, which makes it less scary and more of a normal experience for a child. This can cause problems with addiction later in life.
