    *Notes to Drug Quantity Table:

    (A) Unless otherwise specified, the weight of a controlled substance set forth in the table refers to the entire weight of any mixture or substance containing a detectable amount of the controlled substance. If a mixture or substance contains more than one controlled substance, the weight of the entire mixture or substance is assigned to the controlled substance that results in the greater offense level.

    (B) The terms “PCP (actual)”, “Amphetamine (actual)”, and “Methamphetamine (actual)” refer to the weight of the controlled substance, itself, contained in the mixture or substance. For example, a mixture weighing 10 grams containing PCP at 50% purity contains 5 grams of PCP (actual). In the case of a mixture or substance containing PCP, amphetamine, or methamphetamine, use the offense level determined by the entire weight of the mixture or substance, or the offense level determined by the weight of the PCP (actual), amphetamine (actual), or methamphetamine (actual), whichever is greater.

    The terms “Hydrocodone (actual)” and “Oxycodone (actual)” refer to the weight of the controlled substance, itself, contained in the pill, capsule, or mixture.

    (C) “Ice,” for the purposes of this guideline, means a mixture or substance containing d-methamphetamine hydrochloride of at least 80% purity.

    (D) “Cocaine base,” for the purposes of this guideline, means “crack.” “Crack” is the street name for a form of cocaine base, usually prepared by processing cocaine hydrochloride and sodium bicarbonate, and usually appearing in a lumpy, rocklike form.

    (E) In the case of an offense involving marihuana plants, treat each plant, regardless of sex, as equivalent to 100 grams of marihuana. Provided, however, that if the actual weight of the marihuana is greater, use the actual weight of the marihuana.

    (F) In the case of Schedule I or II Depressants (except gamma-hydroxybutyric acid), Schedule III substances, Schedule IV substances, and Schedule V substances, one “unit” means one pill, capsule, or tablet. If the substance (except gamma-hydroxybutyric acid) is in liquid form, one “unit” means 0.5 milliliters. For an anabolic steroid that is not in a pill, capsule, tablet, or liquid form (e.g., patch, topical cream, aerosol), the court shall determine the base offense level using a reasonable estimate of the quantity of anabolic steroid involved in the offense. In making a reasonable estimate, the court shall consider that each 25 milligrams of an anabolic steroid is one “unit”.

    (G) In the case of LSD on a carrier medium (e.g., a sheet of blotter paper), do not use the weight of the LSD/carrier medium. Instead, treat each dose of LSD on the carrier medium as equal to 0.4 milligrams of LSD for the purposes of the Drug Quantity Table.

    (H) Hashish, for the purposes of this guideline, means a resinous substance of cannabis that includes (i) one or more of the tetrahydrocannabinols (as listed in 21 C.F.R. § 1308.11(d)(31)), (ii) at least two of the following: cannabinol, cannabidiol, or cannabichromene, and (iii) fragments of plant material (such as cystolith fibers).

    (I) Hashish oil, for the purposes of this guideline, means a preparation of the soluble cannabinoids derived from cannabis that includes (i) one or more of the tetrahydrocannabinols (as listed in 21 C.F.R. § 1308.11(d)(31)), (ii) at least two of the following: cannabinol, cannabidiol, or cannabichromene, and (iii) is essentially free of plant material (e.g., plant fragments). Typically, hashish oil is a viscous, dark colored oil, but it can vary from a dry resin to a colorless liquid.

    (J) Fentanyl analogue, for the purposes of this guideline, means any substance (including any salt, isomer, or salt of isomer thereof), whether a controlled substance or not, that has a chemical structure that is similar to fentanyl (N-phenyl-N-[1-(2-phenylethyl)-4-piperidinyl] propanamide).

    (K) The term “Converted Drug Weight,” for purposes of this guideline, refers to a nominal reference designation that is used as a conversion factor in the Drug Conversion Tables set forth in the Commentary below, to determine the offense level for controlled substances that are not specifically referenced in the Drug Quantity Table or when combining differing controlled substances.
