What this bill does
Plain-language analysis by the nonpartisan Legislative Reference Bureau
Under current law in the Uniform Controlled Substances Act, carfentanil is listed as a synthetic opiate under Schedule II. Under this bill, carfentanil is listed as a fentanyl analog under Schedule I. A person who manufactures, distributes, or delivers, or possesses with the intent to manufacture, distribute, or deliver, a fentanyl analog is guilty of a felony, the classification of which is based on the amount involved. If the amount is 10 grams or less, the person is guilty of a Class E felony; if the amount is more than 10 grams but not more than 50, the person is guilty of a Class D felony; and if the amount is more than 50 grams, the person is guilty of a Class C felony.
Because this bill creates a new crime or revises a penalty for an existing crime, the Joint Review Committee on Criminal Penalties may be requested to prepare a report.
