An "Uncontrolled Substance" refers to any drug or chemical that is not regulated by government laws or agencies. Unlike controlled substances, which are monitored due to their potential for abuse or addiction, uncontrolled substances can be legally obtained and used without strict oversight. This category includes many over-the-counter medications and common household products. These substances may still pose risks if misused, but they are generally considered safer for public use. Examples include certain herbal supplements and non-prescription medications. Awareness of their effects and proper usage is essential to ensure safety and prevent potential health issues.
