Amphetamines, whether taken for treatment of depression, for weight control, or illicitly for recreation, can cause severe anxiety to the point of panic. This extreme reaction is also possible with illicit drugs such as cocaine, phencyclidine (PCP), and the hallucinogens (LSD, mescaline). It is possible that these drugs stimulate brain receptors associated with anxiety, making panic attacks more likely. Marijuana causes increased heart rate that can lead to a severe anxiety reaction.

Alcohol withdrawal can produce nervousness, rapid heartbeat, confusion, high blood pressure, and panic as well as other symptoms. Too rapid withdrawal from antidepressants, narcotics, sedatives, barbiturates, benzodiazepines (Valium, Librium, etc.), or beta blockers can cause symptoms such as anxiety, rapid heartbeat, high blood pressure, and panic, especially after longterm use.
