Amphetamines are stimulants that are often prescribed to patients with attention deficit disorder or attention deficit hyperactivity disorder. These drugs cause the central nervous system to work faster, which helps patients concentrate better for a short period of time.
Amphetamines can be physically and psychologically addictive. Some people take more than is prescribed or take the drugs after they are no longer supposed to be using them. It’s especially important to warn young people not to share this medication with friends who are not prescribed the drug because many young people each year become addicted to street versions of these drugs.
Overuse of these drugs can be fatal. If a person uses the drug for a long period of time, he or she might speed up the system too much. Overdoses and prolonged use can lead to sudden cardiac arrest.
