Dive Brief: 

• Colorado last week became the first U.S. state to legalize the recreational use of marijuana for those over 21, opening up a whole new landscape for brands and marketing. 
• Some media companies have been hesitant to take on marijuana-based brands because of state laws restricting marijuana advertising on any media that has over 30% of audience under the age of 21. 
• Yelp and Foursquare are allowing marijuana-based companies to list their businesses, but are banning those establishments from purchasing advertising.

Never before in the time of digital media has the drug been legal and the fact that is only in certain parts of the country complicate things. Those media companies that embrace the marijuana brands stand to make a lot of money so it's worth investigating.
