Plans are to use one of those machines like the Arizona Lottery. The ping pong balls it pop out will determine which of the 486 applicants are going to walk away with a certificate that awards them permission to be one of the 126 sites where marijuana can be sold. Some areas of the state have no applicants. But the district on the east side of Flagstaff, for example, has 13 alone. State health director Will Humble said just being one of those chosen today is not a license to immediately start selling the drug.
