Central nervous system (CNS) stimulants are drugs that act on the brain and spinal cord to increase alertness, attention, and energy. These drugs work by increasing the activity of certain chemicals in the brain, such as dopamine, norepinephrine, and serotonin.
CNS stimulants are commonly used to treat medical conditions such as attention deficit hyperactivity disorder (ADHD), narcolepsy, and obesity. They are also used recreationally for their stimulating effects, such as increased energy, euphoria, and enhanced cognitive performance.
When used as prescribed and under medical supervision, CNS stimulants can be safe and effective. However, misuse or abuse of these drugs can lead to serious health problems, such as addiction, high blood pressure, heart disease, stroke, seizures, and psychosis. It is important to use CNS stimulants only as directed and to talk to a doctor if you have any concerns about their use.
