Meet the Yelp for Medical Marijuana Dispensaries

After California legalized the sale of medical marijuana, hundreds of thousands of people were left hunting down doctors willing to give them prescription cards and searching for local dispensaries--which have the habit of closing abruptly or being buried with invisible signage. One entrepreneur wondered why there wasn't a better way. 

"I realized that these dispensaries could use internet marketing," says Justin Hartfield, CEO of Weedmaps.com. "I was like, wait a minute. Yelp doesn't have any dispensaries. Why don't I make a portal for dispensaries? I could optimize it myself, get the No. 1 on Google. When people click through and see my awesome website, they'll come back next week when they want more weed."
