What are the side effects of amphetamines?
Amphetamines increase the user’s heart rate, breathing rate, and blood pressure rate, and they dull the sensations of hunger and fatigue. The mouth usually becomes dry, and both swallowing and urination are difficult. The user’s pupils become dilated, and reflexes become faster. Oftentimes the user experiences rapid speech followed by slurred speech. Extremely high doses may cause users to flush or become pale and cause a rapid or irregular heartbeat, loss of coordination, and even physical collapse. Amphetamine injections can cause such an intense increase in blood pressure that a high fever, a stroke, or heart failure may result. Anxiety, delirium, hallucination, restlessness, and irritability are also acute toxic effects of amphetamine use.
