The psychosis is manifested by hallucinations, delusions, and paranoia. Bizarre, sometime violent, behavior is exhibited by those with amphetamine psychosis.
Symptoms usually disappear within a few weeks after drug use stops.
Withdrawal Symptoms Amphetamines have the potential to produce tolerance, which means that increased amounts of the drug are needed to achieve the desired effects. Withdrawal symptoms can occur when use of amphetamines is stopped abruptly. The length and severity of the depression is related to how much and how often amphetamines were used. These affect serotonin, the neurotransmitter in the brain that deals with both depression and drug craving. Sedatives such as Dalmane, chloral hydrate, Librium, phenobarbital, or even Valium are used, very carefully, on a short-term basis to treat anxiety or sleep disturbance problems.
