3.       Synergisms and antagonisms among ingredients.

4.       Deterrent or antagonistic effects of the non-controlled ingredients.

5.       Usefulness of and need for the drug in medical therapy. (Information source may include reports of the companies manufacturing preparations; containing the substance in question including its salts, isomers, esters, ethers and salts of isomers, esters, ethers where such chemical designation is possible on the chemical evaluation of said drug with emphasis on the psychic and/or physiological dependence liabilities.

6.       International and foreign listings of dangerous drugs such as:
