Meth Addiction Symptoms & Warning Signs

Understanding Meth Addiction

Learn about meth addiction & abuse

Methamphetamine, otherwise known as meth, is a potent and strong drug. Meth is categorized in the stimulant category of drugs because the use of it increases the activity of the central nervous system. The category of stimulants includes prescription medications such as Ritalin and Adderall, everyday substances like caffeine, and illicit drugs such as amphetamine, cocaine, MDMA (Ecstasy), and meth. In terms of consumption, meth can be snorted, smoked, or dissolved then injected. When meth becomes present in the body, it produces a strong rush of pleasure. This happens as the brain pumps out more dopamine in response to the drug being in the system, which causes feelings of motivation and pleasure to kick in. These effects can cause individuals to keep abusing meth, which can lead to the development of addiction. What is important to know, however, is that there are several options for treatment for those who have found themselves stuck in the dangerous pattern of meth abuse.


Statistics on meth addiction & abuse

According to the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5), nearly 0.2 percent of individuals ages 12 and older have abused an amphetamine-like stimulant within the past year. Intravenous use is three or four times more common among women than men; however, this difference is only notable in those who inject the substance. The National Survey on Drug Use and Health (NS-DUH), reported data from a 2012 study that showed a higher estimate, stating that nearly 0.4 percent of the population (or 1.2 million people) have used meth within the past year.
