How are drugs classified into schedules I-V?

Drugs are classified into schedules I-V based on their medical use, potential for abuse, and the likelihood of causing dependence or harm. This classification system is established by the Controlled Substances Act and is intended to help regulate the availability of substances based on their risk profiles.

Schedule I drugs, for example, are considered to have a high potential for abuse and no accepted medical use, such as heroin or LSD. Conversely, Schedule V drugs have a lower potential for abuse and are recognized for their medical applications, like some cough preparations that contain limited amounts of narcotics. This framework underscores the importance of assessing both the therapeutic benefits and the risks associated with drug use, facilitating informed decisions in healthcare and law enforcement.

Factors such as popularity, cost, or the manufacturing company do not play a role in this classification, as the schedules are strictly focused on the drug's effects and potential for misuse.
