LAS VEGAS (AP) — Las Vegas could soon add recreational marijuana to its list of vices if Nevada approves a Nov. 8 referendum on cannabis.

Supporters see pot as a fitting alternative for tourists tired of $15 cocktails and hangovers. But weed proponents will have to win over closely divided voters and a risk-averse gambling industry.

In spite of their libertine reputation, Nevada's rigorously regulated casinos are known to err on the conservative side to avoid scandalizing the middle-aged tourists who are their bread and butter.

The ballot initiative would not allow municipalities to put blanket bans on marijuana. It would also bar consumption in buildings that are open to the public. Local governments could restrict the locations of dispensaries, and city-dwellers would be effectively banned from growing their own pot.
