What it is
Methamphetamine is a powerful and highly addictive stimulant. Its crystalline form is often called "ice" or "crystal meth", and it may also be sold as a powder or paste. It speeds up the messages between the brain and the body. It is an illegal drug, and what is sold is often impure or mixed with other substances, making each use unpredictable and dangerous.
How it affects you
Methamphetamine causes a large, rapid release of dopamine, producing an intense rush of energy and confidence. This is followed by a difficult "comedown".
- Effects: intense alertness, euphoria, fast heartbeat, raised body temperature, reduced appetite, and the urge to keep moving or talking.
- Comedown / crash: exhaustion, low mood, anxiety, irritability, and strong cravings that can last for days.
- Higher doses can cause aggression, paranoia, hallucinations, and a temporary loss of touch with reality (drug-induced psychosis).
Why it is so addictive
The intense high and the crash that follows can drive people to use again quickly, and dependence can develop fast. Over time, the brain produces less of its own dopamine, so everyday life can feel flat or joyless without the drug, which makes stopping extremely hard without support.
The dangers
- Overdose, with risk of stroke, heart attack, seizures, and dangerously high body temperature.
- Severe mental health effects: paranoia, psychosis, anxiety, and depression.
- Long-term physical harm, including damage to the heart, teeth ("meth mouth"), and significant weight loss.
- Mixing it with other drugs or alcohol greatly increases the risk of harm.
Signs it may be a problem
- Strong cravings, or needing the drug to feel okay.
- Using more to get the same effect, or being unable to stop.
- Big changes in sleep, weight, mood, finances, or relationships.
