Under federal law (applicable in all states) it is illegal for a person to knowingly or intentionally manufacture, distribute, or dispense a controlled substance—or to possess a controlled substance with the intent to manufacture, distribute, or dispense it. It is also illegal to create, distribute, or dispense a counterfeit substance, or to possess a counterfeit substance with the intent to distribute or dispense it.

The term controlled substance means a drug or other substance—or an immediate precursor to the drug or other substance—that is included in schedule I, II, III, IV, or V of the relevant portion of the United States Code (statute). See 21 U.S.C. §841.

The term counterfeit substance means a controlled substance (or its container or labeling) that—without authorization—bears the trademark, trade name, or other identifying mark, imprint, or number of a manufacturer, distributor, or dispenser other than the person or persons who in fact manufactured, distributed, or dispensed the substance. In other words, a counterfeit substance is falsely represented to be manufactured or distributed by an another (presumably authorized) manufacturer, distributor, or dispenser.

It is also illegal for a person to knowingly or intentionally manufacture, distribute, or dispense a controlled substance—or to possess a controlled substance with the intent to manufacture, distribute, or dispense it—under state law. As under federal law, state laws usually classify substances in groups or schedules that determine which substances are included in the definition of controlled substances, and the potential penalties or punishments for distributing them.

Criminal charges and penalties for these offenses vary from state to state and are usually located in a state’s statutes.

Under both federal and Arizona state law, it is illegal to knowingly or intentionally manufacture, distribute, dispense, or possess with intent to manufacture, distribute, or dispense a controlled substance. Controlled substances are classified into schedules I through V, with Schedule I substances being considered the most dangerous and having a high potential for abuse with no accepted medical use. The classification of these substances is outlined in 21 U.S.C. §841 for federal law and mirrored in Arizona's statutes. Additionally, it is illegal to create, distribute, or dispense counterfeit substances, which are drugs that are falsely represented as being produced by an authorized manufacturer. In Arizona, the penalties for these offenses can be severe and vary depending on the schedule of the controlled substance involved, the quantity, and other factors such as distribution near school zones or to minors. These regulations are designed to control the misuse of drugs and to prevent the illegal drug trade.
