In News: Sonali Phogat (Actor and a Politician) who was recently killed by giving the recreational drug methamphetamine on the eve of her death.

The stimulant drug
- Methamphetamine — meth for short — is a powerful, highly addictive stimulant that affects the central nervous system, and is used to treat attention-deficit hyperactivity disorder (ADHD) and narcolepsy, a sleep disorder.
- Crystal methamphetamine or crystal meth is a form of the drug that looks like glass fragments or shiny, bluish-white rocks.
- It is chemically similar to amphetamine.
- Methamphetamine can be smoked, swallowed in the form of a pill or tablet, snorted, and injected after dissolving the powder in water or alcohol.
- Methamphetamine can lead to myocardial infarction (heart attack); it can cause stroke.
- The drug can affect the heart, the brain, and the kidneys. It can result in the blood pressure shooting up suddenly. So, it is a very dangerous drug if there is an overdose.
Effect on the brain
- Meth raises the amount of dopamine in the brain.
- Dopamine, a natural chemical, plays a role in body movement, motivation, and reinforcement of rewarding behaviours.
- The ability of the drug to rapidly release high levels of dopamine in reward areas of the brain strongly reinforces drug-taking behaviour, making the user want to repeat the experience.
Role in heart attack
- Methamphetamine on its own might not cause the heart attack but it can result in a cardiac arrest if consumed in an excess quantity.
- The recreational drug can lead to over sedation, which can affect the organs, including the heart.
- It affects the cardiovascular system by triggering blood vessel spasms and life-threatening spikes in blood pressure.
- It can also increase plaque in the arteries and rewire the heart’s electrical system.
- It leads to narrowing and spasms in the blood vessels, rapid heart rate (tachycardia), high blood pressure, and death of cardiac muscles.
