Methamphetamine addiction is characterized by a physical and emotional dependence on a stimulant medication commonly referred to as meth or crystal meth. This drug triggers chemicals in the brain that are responsible for creating pleasure and can quickly cause a person to feel unable to function without it. Signs of a methamphetamine addiction may include decreased appetite, obsessive behavior, and agitation. Prolonged use of this drug is known to result in significant tooth decay. Hair loss, heart problems, and psychosis are common long-term effects of a methamphetamine addiction.
Many people begin using methamphetamines out of curiosity or as a way to boost energy levels. Those who wish to lose weight may also be attracted to this type of drug. The initial rush and boost of energy quickly disappear, causing the person to crash or feel tired and depressed. In an effort to recreate the original feeling, more of the drug may be taken, often leading to a dependence referred to as a methamphetamine addiction. Over time, more and more of the drug is required, frequently causing a potentially fatal overdose situation.
Immediately after using meth, a feeling of euphoria is common. High energy levels and increased productivity are possible, adding to the initial appeal. These effects fade rapidly and often transition into feelings of agitation or irritability. The drug user may become hostile and combative and may even begin to lie and steal from loved ones in order to continue with the addiction. Rapid weight loss, tooth decay, and behavior changes are among the most noticeable signs of a methamphetamine addiction.
Mental and emotional changes tend to worsen over time as the methamphetamine addiction continues. Confusion, impaired judgment, and risky sexual behavior are often seen among addicts. A person who is normally kind and relaxed may suddenly pick fights and seem to be constantly on edge. Obsessive behavior such as frequent hand washing or constant concern about appearance is a common development. Psychosis may develop and may involve hallucinations, delusions, and paranoia.
Long-term use or increased dosages can have extremely damaging effects on the body. Decreased appetite caused by this drug may lead to eating disorders or malnutrition. The teeth may become so decayed that infections develop that, if left untreated, can cause abscesses, which may cause the infection to move into the bloodstream. Methamphetamine usage makes the heart work harder, leading to complications such as high blood pressure or increased heart rates, which can be fatal.
