Marijuana is legal in Las Vegas for adults 21 and over. Nevada legalised recreational cannabis by ballot measure and licensed retail sales began in July 2017. Buying requires a valid government-issued photo ID and must happen at a state-licensed dispensary.

You cannot legally smoke weed in a Las Vegas hotel room. Nevada bans cannabis consumption in public, in vehicles and in casinos, and Strip resorts prohibit it in their own policies because they hold federal gaming licences. Legal consumption in Las Vegas means a private residence or a state-licensed consumption lounge.

You cannot legally take cannabis bought in Las Vegas out of Nevada. Crossing a state line with cannabis is a federal offence regardless of the law at either end, which covers driving to California or Arizona and flying out of Harry Reid International Airport.
