Stimulansi

Stimulansi, also known as stimulants, are a class of psychoactive drugs that increase alertness and attention, as well as elevate mood, energy, and arousal. They work by affecting the central nervous system, primarily by increasing the levels of neurotransmitters such as dopamine, norepinephrine, and serotonin. Common examples of stimulants include caffeine, nicotine, amphetamines, and cocaine.

These substances can be consumed in various ways, including ingestion, inhalation, injection, or transdermal application. The effects of stimulants can vary greatly depending on the specific drug, the dosage, and the individual's physiology and psychological state. Short-term effects often include increased heart rate, blood pressure, and body temperature, along with reduced appetite and a feeling of euphoria.

While stimulants can be used for medicinal purposes, such as treating conditions like attention deficit hyperactivity disorder (ADHD) and narcolepsy, they also carry risks. Recreational use can lead to addiction, tolerance, and withdrawal symptoms. Overconsumption can result in serious health consequences, including cardiovascular problems, anxiety, paranoia, and psychosis. Long-term use can have detrimental effects on mental and physical health. The legal status and availability of stimulants vary widely by jurisdiction.
