Methamphetamine (Meth) —What It Is and What It Does
Methamphetamine is a drug that causes over-stimulation of the body’s nerve endings to increase energy and focus, elevate one’s moods and produce false feelings of euphoria. Much like the effects of cocaine on the brain’s dopamine receptors, methamphetamine clicks into dopamine receptor docks to let the brain know it should release dopamine. When adolescents take this drug, the repercussions on the brain and body are immediate and substantial, with a high risk for long term damage.
The high point or “rush” from methamphetamine typically peaks minutes after taking it and can last for up to 12 full hours. Because the high quickly ebbs after the initial euphoria, users often take more of the drug within a single session creating a “binge” habit necessary to extend the high. The contrast between the extreme high and extreme low when taking meth only serves to strengthen the addiction.
