Controlled Substance

Primary tabs

A "controlled substance" means a drug, substance, or immediate precursor defined by State and Federal Controlled Substances Act. The Uniform Controlled Substances Act was drafted to maintain uniformity between the laws of the several states and those of the federal government. Under the Controlled Substances Act, it is unlawful, inter alia, for any person to manufacture, sell, prescribe, distribute, dispense, administer, possess, have under his or her control, abandon, or transport a controlled substance, except as expressly provided by the Act.

A "controlled substance analog" is a substance the chemical structure of which is substantially similar to the chemical structure of a controlled substance. A controlled substance analog is treated the same as a controlled substance for purposes of the criminal law.

Substances controlled under the Controlled Substances Act include:

●     Opiates, fentanyl derivates, and opium derivatives, including heroin

●     Hallucinogenic substances, including LSD

●     Systemic depressants and other depressants

●     Stimulants

●     Substances produced directly or indirectly by extraction from substances of vegetable origin, or independently by means of chemical synthesis, or by a combination of extraction and chemical synthesis, including opiates, stimulants, and depressants

●     Narcotics

●     Anabolic steroids

●     Anticonvulsants

●     Synthetic cannabinoids

Special Cases

●      Although marijuana is a controlled substance under the Federal Controlled Substances Act, the mere use of marijuana is not a federal offense. See also Medical Marijuana.

●      Under the Uniform Controlled Substances Act, alcohol is not a controlled substance.
