What is the definition of a controlled substance?

A controlled substance is defined specifically as a drug or chemical whose manufacture, distribution, possession, and use are regulated by the government under controlled substances laws. This definition primarily includes scheduled drugs, with a focus on narcotics, stimulants, depressants, and hallucinogens that have a high potential for abuse and dependence.

Scheduled drugs are classified by their potential for abuse and accepted medical use, ranging from Schedule I substances, which have no accepted medical use and a high potential for abuse, to Schedule V substances, which have lower potential for abuse. The regulation ensures that these substances are used safely and responsibly in healthcare settings.

In contrast, over-the-counter drugs and any prescription drugs do not inherently fall under the category of controlled substances. Over-the-counter medications are available without a prescription and may not carry the same level of regulatory scrutiny due to their lower potential for abuse. Prescription drugs, while they may include controlled substances, can also encompass medications that are not classified as controlled.

Thus, the definition of a controlled substance is specifically tied to the regulatory framework surrounding scheduled drugs, particularly narcotics. This distinction is important for understanding the legal implications and responsibilities associated with handling such substances in the practice of respiratory care and other healthcare fields.
