(A) Opium and opiate, and any salt, compound, derivative, or preparation of opium or opiate, excluding apomorphine, dextrorphan, nalbuphine, nalmefene, naloxone, and naltrexone, and their respective salts, but including:
(ii) Unless specifically excepted or unless listed in another schedule, any of the following opiates, including their isomers, esters, ethers, salts, and salts of isomers, esters, and ethers, when the existence of the isomers, esters, ethers, and salts is possible within the specific chemical designation, except dextrorphan and levopropoxyphene:
(iii) Unless specifically excepted or unless listed in another schedule, any material, compound, mixture, or preparation that contains any quantity of the following substances having a stimulant effect on the central nervous system:
(iv) Unless specifically excepted or unless listed in another schedule, any material, compound, mixture, or preparation that contains any quantity of the following substances having a depressant effect on the central nervous system, including its salts, isomers, and salts of isomers when the existence of the salts, isomers, and salts of isomers is possible within the specific chemical designation:
(v)
(c) Schedule III:
(i) Unless specifically excepted or unless listed in another schedule, any material, compound, mixture, or preparation that contains any quantity of the following substances having a stimulant effect on the central nervous system, including its salts, isomers whether optical, position, or geometric, and salts of the isomers when the existence of the salts, isomers, and salts of isomers is possible within the specific chemical designation:
(ii) Unless specifically excepted or unless listed in another schedule, any material, compound, mixture, or preparation that contains any quantity of the following substances having a depressant effect on the central nervous system:
(v) Unless specifically excepted or unless listed in another schedule, any material, compound, mixture, or preparation containing limited quantities of any of the following narcotic drugs, or their salts calculated as the free anhydrous base or alkaloid:
(vi) Unless specifically excepted or unless listed in another schedule, anabolic steroids including any of the following or any isomer, ester, salt, or derivative of the following that promotes muscle growth:
(d) Schedule IV:
(ii) Unless specifically excepted or unless listed in another schedule, any material, compound, mixture, or preparation that contains any quantity of the following substances, including its salts, isomers, and salts of isomers when the existence of the salts, isomers, and salts of isomers is possible within the specific chemical designation:
(iv) Unless specifically excepted or unless listed in another schedule, any material, compound, mixture, or preparation that contains any quantity of the following substances having a stimulant effect on the central nervous system, including its salts, isomers whether optical, position, or geometric isomers, and salts of the isomers when the existence of the salts, isomers, and salts of isomers is possible within the specific chemical designation:
(e) Schedule V:
(i) Any compound, mixture, or preparation containing any of the following limited quantities of narcotic drugs, or their salts calculated as the free anhydrous base or alkaloid, which includes one or more non-narcotic active medicinal ingredients in sufficient proportion to confer upon the compound, mixture, or preparation valuable medicinal qualities other than those possessed by the narcotic drug alone:
