Methamphetamine increase levels of the neurotransmitter dopamine, which stimulates brain cells, enhancing mood and body movement. Short-Term Effects When methamphetamine is injected or smoked it immediately produces an intensely pleasurable sensation known as a “rush” or a “flash” by releasing high levels of dopamine in the brain. Snorting methamphetamine produces an euphoric sensation, but not a rush. Even taken in small amounts, methamphetamine can cause: • Increased wakefulness. • Increased physical activity. • Decreased appetite. • Increased respiration. • Hyperthermia. • Increased heart rate and blood pressure. • Irregular heart beat. • Cardiovascular collapse. Other effects of meth use on the central nervous system can produce the following symptoms: • Irritability. • Prolonged insomnia. • Confusion. • Anxiety. • Tremors.
