Can state or local police arrest me for using medical marijuana in Las Vegas, Nevada?
Once the Nevada State Health Division admits you into the Nevada Medical Marijuana Program, and as long as you abide by their strict guidelines (discussed in later questions), then neither you nor your caregiver can be prosecuted in Nevada for marijuana possession, cultivation, trafficking, possession of paraphernalia, or aiding and abetting with the possession and production of marijuana. However, if you or your caregiver ever strays from these guidelines, then you may be prosecuted for possession and related crimes. (NRS 453A.200)
Furthermore, being admitted into the Nevada Medical Marijuana Program doesn’t diminish your responsibility to follow public health and safety laws: You may never sail, fly or drive under the influence of medical marijuana, you may never possess a firearm in public under the influence of medical marijuana; and you may not even go on an amusement park ride if you’re under the influence of medical marijuana. (NRS 484.379, 488.400, NRS 493.130, NRS 202.257, NRS 455B.080)
Can federal authorities arrest me for using medical marijuana in Las Vegas, Nevada?
Yes, but chances are the feds will not come after you. Although the federal government still fails to recognize the legality of medical marijuana programs and may therefore arrest you for possessing medical marijuana in Nevada, no card-holding member of the Nevada Medical Marijuana Program has been arrested yet!
Currently, the Drug Enforcement Administration is focusing its efforts on large-scale drug traffickers, not individuals and their caregivers licensed by their state to use medical marijuana. So as long as the state of Nevada has granted you the right to use medical marijuana, you probably won’t face federal prosecution.
