Dextromethorphan affects the brain by acting on the central nervous system, specifically targeting NMDA receptors. This action can lead to suppression of the cough reflex. In higher doses, it can produce euphoria or hallucinations due to its effect on neurotransmitter systems in the brain, which is why it’s sometimes abused. However, misuse can result in serious side effects like dizziness, confusion, or even brain damage.
