MEMORANDUM AND JUDGMENT
Petitioner was found guilty of unauthorized drug use after two EMIT tests yielded positive results for the presence of opiates in his urine. The test results provide substantial evidence to support the determination (see, Matter of Lahey v. Kelly, 71 N.Y.2d 135) and petitioner's claim that the medication he had taken at least 10 days before the tests caused false-positive results was refuted by the testimony of a facility pharmacist (see, Matter of Gasbara v. Selsky, 268 A.D.2d 732). The documentary evidence and testimony of the correction officer who conducted the tests demonstrate the lack of merit in petitioner's claims regarding the chain of custody and testing procedures (see, Matter of Mitchell v. Goord, 272 A.D.2d 696). Petitioner's claims of bias and that the Hearing Officer improperly interviewed a witness are also unsupported by the record, which demonstrates that the determination was based on the testimony and documentary evidence of petitioner's guilt presented at the hearing.
ADJUDGED that the determination is confirmed, without costs, and petition dismissed.
