'Speed' May Cause Long-Term Damage to the Brain
- Methamphetamine is an illegal, recreational drug also known as meth, speed,
crank, crystal, glass, chalk, or ice.
- Researchers have found that former meth users experience long-term brain
damage, and it is unknown whether the damage can ever be reversed.
- The finding may explain why meth users can have long-lasting behavioral
problems, such as violence, psychosis, and personality defects, for years after
the last time they used the drug.
