Understanding Meth Addiction

Learn about meth addiction

Methamphetamine, or meth, addiction is a type of substance use disorder that involves consistent consumption of increasing amounts of meth. Meth is a drug in the class of stimulants, which are substances that cause a sharp increase in energy levels and elevated mood.

Using meth causes an individual to experience signs and symptoms that have an impact on the body and the mind. Several mental and physical effects that are related to the use of this stimulant include meth craving, tolerance, and withdrawal. Cravings for meth occur when an individual has a strong urge or desire to consume the substance. The desire and search for this substance often impairs an individual’s ability to complete typical daily tasks and responsibilities.

Tolerance to meth develops as a result of an individual regularly consuming the substance in increasing quantities. At that point, the body develops a dependence on the substance. When an individual no longer consumes large quantities of meth or entirely stops using meth, the body responds by entering a state of withdrawal.

It is important to note that meth is one of the most addictive substances, with some cases of meth addiction developing less than one week after initial use. For these reasons, it is vital to seek appropriate care quickly if you believe that you or a loved one may have developed a meth addiction.
