"Methamphetamines" Natural Recordings by Native Speakers
Methamphetamines are a type of highly addictive and illegal drug that can produce feelings of intense happiness, energy, and alertness. They are also known as "speed" or "crystal meth" and are usually taken orally, snorted, or injected. Methamphetamines work by releasing high levels of dopamine, a neurotransmitter that regulates feelings of pleasure and reward, in the brain, leading to a rapid increase in heart rate, blood pressure, and body temperature. Long-term use of methamphetamines can cause significant physical and psychological damage, including cardiovascular problems, malnutrition, and psychosis.

Methadone is a synthetic opioid medication used to treat opioid use disorder (OUD), also known as addiction to heroin or other opioids. It works by attaching to the opioid receptors in the brain, but unlike other opioids, it does not produce a "high" and does not activate the brain's reward system.

It can also be used as a pain medication, particularly for individuals who have developed tolerance to other opioids.

It is often caused by exposure to certain drugs, including local anaesthetics and antimalarials, as well as other toxic substances. In severe cases, methaemoglobinaemia can be life-threatening, requiring immediate medical treatment.
