MEMORANDUM AND JUDGMENT
Petitioner, a prison inmate, was found guilty of using a controlled substance after two tests on petitioner's urine yielded positive results for the presence of opiates. Contrary to petitioner's contention, the misbehavior report, positive test results and testimony presented at the hearing provide substantial evidence of petitioner's guilt (see, Matter of Aviles v. Selsky, 264 A.D.2d 883). Furthermore, given the testimony of the correction officer who conducted the urinalysis tests and documentary evidence presented at the hearing, we reject petitioner's challenge to the sufficiency of the chain of custody and adequacy of the testing procedures used (see, Matter of Rivera v. Goord, 258 A.D.2d 858; Matter of Medina v. Goord, 249 A.D.2d 655). Petitioner's remaining contentions, including his speculative claims that the request form was fabricated and that he was denied relevant documentary evidence, have been reviewed and found to be unpersuasive.
Cardona, P.J., Crew III, Peters, Graffeo and Lahtinen, JJ., concur.
