Y50: Central nervous system stimulants, not elsewhere classified

Central nervous system stimulants, not elsewhere classified, refer to a group of substances or drugs that primarily act on the central nervous system, which includes the brain and spinal cord. When these substances are introduced into the body, they significantly enhance or accelerate the activities of the central nervous system, leading to increased alertness, attention, energy, and even elevated mood. Some common examples of these substances may include certain medications and recreational drugs, while some are not specifically defined under other categories. Common symptoms associated with the use of these substances can range from increased heart rate, high blood pressure, insomnia, to rapid breathing, and even severe mood swings. Over time, repeated misuse of these substances can lead to a variety of health issues such as heart disease, mental health disorders, and addiction. They are typically transmitted through ingestion, inhalation, or injection. Different stimulants can impact the body differently, and the progression of associated impairments or disorders heavily depends on the individual's usage pattern, health condition, and the specific substance involved.
