Methamphetamine is a highly addictive synthetic drug that mimics the effects of adrenaline. It provides an initial rush and sustained high when inhaled or injected, but leads to negative health effects and addiction. Extended use can cause paranoia, aggression, and psychosis. Meth is associated with family violence, accelerated tooth decay ("meth mouth"), sores that take long to heal, transmission to babies through the womb or breastfeeding, and increased risk of disease from unsafe drug use and sex practices while under the influence. A mother in Indiana was arrested for child neglect after leaving her children at home with the dead body of a man she had used meth with.
