Signs and Symptoms of Use

• Mood changes
• Impaired concentration
• Impaired mental functioning
• Swings between apathy and alertness

In addition to the physical effects, users report feeling restless, anxious and moody. Higher doses intensify the effects. Persons who use large amounts of amphetamines over a long period of time can develop an amphetamine psychosis that includes hallucinations, delusions and paranoia. These symptoms usually disappear when drug use ceases.
