Crystal meth, short for crystal methamphetamine, is a powerful and highly addictive stimulant drug. It appears as clear, bluish-white crystals and is often smoked, snorted, or injected. The drug affects the central nervous system, leading to increased energy, alertness, and euphoria, but it can also cause severe health issues. Long-term use of crystal meth can lead to serious physical and mental health problems, including addiction, heart issues, and severe dental problems often referred to as "meth mouth." Additionally, it can result in significant changes in behavior, including aggression and paranoia, impacting relationships and daily life.
