Methamphetamines are a stimulant that travels to the part of the brain that releases ‘dopamine’; the chemical that is key to human pleasure. The more dopamine released, the better the person feels.

Methamphetamines have the ability to trigger an excessive production of dopamine in the brain. In fact, one dose of methamphetamines can release more than 1200 units of the chemical producing a rush that is six times more than the body can produce and three and a half times more than cocaine. The high can last for up to 12 hours, but with this prolonged high is inevitably followed by a huge fall.

The long term effects of methamphetamines on the brain are not fully understood. However, scientists have managed to find out that over time addicts will fail to experience any pleasure at all, with or without the drug. This is because methamphetamines can permanently damage the neurons in the brain that produce dopamine. Eventually methamphetamine users go from having too much dopamine to having none at all.
