Amphetamines and Methamphetamines are commonly referred to as "speed" or "uppers". These drugs are stimulants that increase activity in the central nervous system, leading to increased energy, alertness, and euphoria. They can be taken orally, inhaled, or injected, and are often abused to enhance performance or stay awake for long periods of time. Amphetamines are legally prescribed for attention deficit hyperactivity disorder (ADHD) and narcolepsy, while methamphetamine is classified as an illicit drug.

Amphetamines work by increasing the release and blocking the reuptake of certain neurotransmitters, such as dopamine, norepinephrine, and serotonin. This leads to an increase in their concentration in the brain, which affects mood, energy levels, and the body's response to stress. Methamphetamine, being a more potent and longer-lasting form of amphetamine, produces a more intense and longer-lasting high, making it more addictive and potentially more harmful.

Amphetamines and methamphetamines can have several short-term and long-term effects on the body. In the short-term, these drugs can cause increased heart rate, elevated blood pressure, decreased appetite, dilated pupils, and increased energy and focus. However, they can also lead to insomnia, agitation, paranoia, and even psychosis in some cases. Long-term use can result in addiction, cardiovascular problems, dental issues (often referred to as "meth mouth"), and neurological damage. It's important to note that the severity of these effects can vary depending on the dose, frequency of use, and individual factors.
