In this regard, the Court of Appeals has instructed that “the test for determining whether an item is dangerous contraband is whether its particular characteristics are such that there is a substantial probability that the item will be used in a manner that is likely to cause death or other serious injury, to facilitate an escape, or to bring about other major threats to a detention facility’s institutional safety or security” … . Notably, “the distinction between contraband and dangerous contraband” does not turn upon “whether an item is legal or illegal outside of prison . . . [as] [i]t is obvious that an item, such as a razor, may be perfectly legal outside prison and yet constitute dangerous contraband when introduced into that unpredictable environment” … . Similarly, as our case law makes clear, the item in question need not be inherently dangerous in order to qualify as dangerous contraband. Indeed, although weapons are perhaps the most commonly recognized source of dangerous contraband in a prison setting … , courts have — applying the Finley test — reached the very same conclusion with respect to other items made, obtained or possessed by prison inmates, including illegal quantities of drugs …, a disposable Bic lighter …  and hand-drawn maps or knotted links of wire that could be used to facilitate an escape …. Although the majority in Finley did not expressly address this issue, Judge Pigott opined in his concurrence/dissent that, “[i]f the contraband at issue is not inherently dangerous . . . , the People must present specific, competent proof from which the trier of fact may infer that use of the contraband could potentially create a dangerous situation inside the facility” … . As a cell phone admittedly is not an inherently dangerous item, the question is whether the People adduced sufficient proof to establish the cell phone’s potential to be used in such a pernicious manner as to elevate it to the level of dangerous contraband. People v Green, 2014 NY Slip Op 03303, 3rd Dept 5-8-14

As noted by County Court, contraband will be considered dangerous under the statutory definition as long as it endangers the safety of “any person” (Penal Law § 205.00 [4]). Inasmuch as the heroin possessed by defendant clearly endangered his own safety, and he freely admitted that he used it to harm himself, there was legally sufficient evidence from which the jury could reasonably conclude that it constituted dangerous contraband and we do not find that the verdict was against the weight of the evidence… . People v Verley, 2014 NY Slip Op 07208, 3rd Dept 10-23-14
