In heavy-ion collisions at RHIC and the LHC, a suppression of the nuclear modification factor for jets along with other strongly interacting particles has been observed relative to proton-proton collisions. To unambiguously determine if this suppression is due to the creation of a strongly interacting medium of de-confied partons referred to as the Quark-Gluon Plasma, or due to Cold Nuclear Matter effects, a "control experiment" is required. Proton-lead collisions serve as this control experiment, because these colli- sions are expected to be sensitive to cold nuclear matter effects while not producing a QGP at this collision energy ({591}sNN = 5.02 TeV). Presented in this defense are the first measurements of charged + neutral jets in p-Pb collisions using the ALICE detector at the LHC. Measurements of CNM effects are done via the nuclear modification factor for jets: RpPb, RCP, and the jet structure ratio. Measurements of the jet spectrum along with a detailed and proper discussion of the statistical, systematic, and normalization uncertain- ties will be presented. Also a comparison of RpPb and RCP measured in this analysis to other measured RpPb and RCP from ATLAS and CMS will be presented. All the measurements performed in this analysis indicate that no strong cold nuclear matter effects are observed in p-Pb collisions using the ALICE detector at the LHC.
