What are controlled substances?
A controlled substance is any type of drug that the federal government has categorized as having a higher-than-average potential for abuse or addiction. Such drugs are divided into categories based on their potential for abuse or addiction. Controlled substances range from illegal street drugs to prescription medications.
What are precursor chemicals?
Precursor chemicals are chemicals that are essential to the production of a controlled substance. Precursor chemicals have a wide legitimate use in the production of consumer goods such as pharmaceuticals, fragrances, flavouring agents, petroleum products, fertilizers and paints. For example, ephedrine and pseudoephedrine, commonly used in cold and decongestant medicine, are precursor chemicals that are used to produce methamphetamine.
