Abuse unit

Texas law defines "Abuse unit" thus (Health and Safety Code, Title 6, Subtitle C, Chapter 481, Subchapter A, Section 481.002): (A) except as provided by Paragraph (B): (i) a single unit on or in any adulterant, dilutant, or similar carrier medium, including marked or perforated blotter paper, a tablet, gelatin wafer, sugar cube, or stamp, or other medium that contains any amount of a controlled substance listed in Penalty Group 1-A, if the unit is commonly used in abuse of that substance; or (ii) each quarter-inch square section of paper, if the adulterant, dilutant, or carrier medium is paper not marked or perforated into individual abuse units; or (B) if the controlled substance is in liquid or solid form, 40 micrograms of the controlled substance including any adulterant or dilutant. The most well-known substance in "Penalty Group 1-A" is LSD. The term "Abuse unit" is used in order to fairly prosecute possession or manufacture of drugs that are usually dosed with blotter paper (and other hard-to-measure mediums).
