Matter of Sanchez-Cornejo, 25 I. & N. Dec. 273 (BIA 2010)

Texas conviction of delivery of a simulated controlled substance, as defined by 482.001(4) of the Texas Health and Safety Code, is not an aggravated felony drug trafficking offense because federal law does not punish distribution of a non-controlled substance in place of a real controlled substance; the violation is, however, a controlled substances offense for purposes of triggering removability under INA 237(a)(2)(B).

For NY Controlled Substance Convictions the sale of actual controlled substances may not be a crime related to a controlled substance. See U.S. v. Minter, No. 21-3102 (2d Cir. 2023).
