psychoactive drugs
Psychoactive drugs are substances that affect the brain's function, altering mood, perception, and behavior. They work by interacting with neurotransmitters, which are chemicals in the brain that transmit signals between nerve cells. These drugs can be natural, like caffeine and marijuana, or synthetic, like prescription medications and recreational drugs. Depending on their type, they can produce effects ranging from relaxation and euphoria to anxiety and hallucinations. While some psychoactive drugs have medicinal uses, others can lead to addiction or adverse health effects when misused. Their impact on individuals can vary widely based on factors like dosage and personal sensitivity.
