MEMORANDUM AND JUDGMENT
Petitioner challenges a determination finding him guilty of violating the prison disciplinary rule prohibiting the unauthorized use of a controlled substance after his urine twice tested positive for the presence of cannabinoids. Contrary to petitioner's contention, the misbehavior report, the two positive urinalysis test results and the testimony presented at the disciplinary hearing provide substantial evidence of his guilt (see Matter of Gonzales v. Selsky, 301 A.D.2d 1019, 1020; Matter of Irons v. Goord, 283 A.D.2d 705). Petitioner's assertion that the medications he was taking at the time of the urinalysis testing resulted in false positive results was countered by testimony of a nurse at the facility's medical unit, as well as by that of a representative from the manufacturer of the urinalysis testing system who opined that the medications in question were incapable of producing false positive test results for the presence of cannabinoids (see Matter of Woods v. Selsky, 291 A.D.2d 773; Matter of Rowe v. Goord, 289 A.D.2d 764).
We reject the contention that petitioner was improperly denied the right to call certain witnesses as the testimony they had to offer would have been either redundant to that given by other witnesses or irrelevant (see Matter of Madison v. Goord, 273 A.D.2d 557, 558). The remaining contentions raised herein have been examined and found to be unpersuasive.
Cardona, P.J., Crew III, Spain, Mugglin and Lahtinen, JJ., concur.
ADJUDGED that the determination is confirmed, without costs, and petition dismissed.
