Nikotin (Stimulant)
Nikotin is a natural stimulant found in the leaves of the tobacco plant. It acts on the brain by increasing the release of neurotransmitters, which can enhance mood and alertness. While it can create feelings of pleasure and relaxation, it is also highly addictive, leading many users to develop a dependence on it.
When consumed, either through smoking or other methods, nikotin can increase heart rate and blood pressure. Its effects are often short-lived, prompting users to seek more to maintain the desired effects. Long-term use is associated with various health risks, including lung disease and cardiovascular problems.
