Amphetamines (including speed) are a group of stimulant drugs used to stay awake, energised and alert.
Speed, also known as amphetamines, is a stimulant drug that is used to increase alertness, focus, and energy. It is often used to treat conditions such as attention deficit hyperactivity disorder (ADHD) and narcolepsy, a sleep disorder that causes excessive daytime sleepiness.
Speed is available in several forms, including tablets, capsules, and as a powder that can be inhaled or injected. When taken in high doses or used recreationally, it can produce a feeling of euphoria and can be addictive.
Long-term use of amphetamines can lead to a number of negative side effects, including insomnia, weight loss, and irregular heart rhythm. It can also increase the risk of mental health problems, such as anxiety and psychosis.
It is worth noting that amphetamines are classified as controlled substances in many countries and are illegal to use without a prescription.
