Las Vegas is a palace built to giant temples of entertainment. And now the city will also hold the world's biggest temple to marijuana. The world's largest marijuana dispensary in the world will open in Las Vegas on Thursday. The dispensary is called Planet 13, and in typical Vegas fashion features giant LED Lotus Flowers on top of the building, a LED water fountain, a graffiti wall where people can use lasers to write on it and there will supposedly be 47 wide-screen TVs throughout the facility. Planet 13 will be 2,300 square feet and will bring in an estimated 2,000 customers each day.
