Methamphetamine is a highly addictive, simulant drug that affects your central nervous system in the form of a white powder or pill. Crystal methamphetamine is a form of the drug that looks like glass fragments or shiny, blueish white rocks. Methamphetamine can cause a rapid and/or irregular heartbeat, increased blood pressure and body temperature, and other effects on your brain, and can cause severe depression, psychosis, and anxiety in withdrawal. Dangerous, synthetic opioids such as fentanyl are sometimes added to street methamphetamine without the user knowing, leading to a greater risk of overdose death.
