Substance abuse, also known as drug abuse, is the use of a drug in amounts or by methods which are harmful to the individual or others.It is a form of substance-related disorder.Differing definitions of drug abuse are used in public health, medical and criminal justice contexts. See Application Note 8. Case 178/84. Physical properties include color, density, hardness, and melting and boiling points. When using a spectrophotometer to determine concentration of a sample solution of unknown concentration by UV/VIS spectroscopy, a calibration line must first be created. Other features used to determine the purity of substances are vapor pressure, refractive index and density for gases, liquids, and solids respectively. Judgment of the Court of 12 March 1987. In the case of a controlled substance that is not specifically referenced in this guideline, determine the base offense level using the converted drug weight of the most closely related controlled substance referenced in this guideline.
