Question

Quizplus · Accepted Answer

Methamphetamine is a stimulant that increases the release and blocks the reuptake of dopamine, leading to a buildup of dopamine in the synapses. This is similar to cocaine, which also increases dopamine levels through similar mechanisms. Opiates, such as heroin, bind to the opioid receptors in the brain, leading to a decrease in pain perception and increased feelings of pleasure, but they do not directly increase dopamine levels in the same way that methamphetamine and cocaine do. Marijuana primarily acts on the cannabinoid receptors in the brain, leading to a range of effects such as altered perception, mood changes, and increased appetite, but it does not have a direct impact on dopamine levels.
