Metampetamiini

Metampetamiini is a synthetic stimulant drug that affects the central nervous system. It is chemically related to amphetamine but is more potent and has a longer-lasting effect. Metampetamiini can be produced in powder form, which is typically white and crystalline, or as a crystalline rock known as "crystal meth."

The drug is most commonly taken by smoking, snorting, injecting, or orally. Upon ingestion, metampetamiini triggers the release of dopamine, a neurotransmitter associated with pleasure and reward. This surge in dopamine leads to intense euphoria, increased energy, alertness, and a decreased need for sleep and food.

However, the effects are often followed by a "crash" characterized by fatigue, depression, and irritability. Chronic use of metampetamiini can lead to severe health problems, including dental decay ("meth mouth"), skin sores, paranoia, hallucinations, anxiety, and significant psychological dependence. It can also cause cardiovascular issues such as rapid heart rate and high blood pressure, increasing the risk of stroke and heart attack. The drug is highly addictive, and withdrawal symptoms can be severe and prolonged. In many countries, metampetamiini is a controlled substance due to its high potential for abuse and associated dangers.
