What are the risks of amphetamine and methamphetamine abuse?
Amphetamine and methamphetamine abuse can cause serious cardiovascular problems, visual hallucinations, tremors, loss of coordination, and, in extreme cases, death from stroke or heart failure.
Furthermore, a recent study found that 26 former methamphetamine users showed losses of neurons and other brain chemical abnormalities even after abstaining for an average of four months. The report concluded that these glitches lend evidence for long-term cognitive problems, and the death of neurons that release dopamine may contribute to ongoing depression in chronic users who have kicked the habit.
Chronic intravenous abuse can cause permanent blood vessel damage, and needle sharers are at a greater risk for contracting infectious diseases such as AIDS. Paranoia, anxiety, and sudden bursts of aggression may also occur in those addicted to injected methamphetamine (perhaps because it is often mixed with PCP).
These psychological symptoms can lead to homicidal or suicidal thoughts, and anecdotal evidence points to methamphetamine abusers showing more violent tendencies than cocaine abusers.
