MONTEVIDEO, Uruguay (AP) — President Jose Mujica says Uruguay's legal marijuana market will be much better than the system in Colorado, which doesn't track the drug after sale. And he says the medical marijuana laws many U.S. states have adopted are based on "hypocrisy" because they enable people to fake illnesses to get prescription weed.

Mujica also predicted Friday that Uruguay's system will be much tougher on drug users, and more effective in combatting illegal drug trafficking.

Mujica, who will visit President Barack Obama in the White House on May 12, says his government will license and regulate the entire marijuana business, enforcing pot possession rules as well as limits on production and sales so that violators get punished and addicts get help.

Online ad industry wrestles with how to handle bumper crop of new ad budgets

Pot is legal in Colorado but not on Google and Twitter. At least not yet.

A million-dollar-a-day industry is budding out West, but marketers are trying to grapple with how to advertise the once illegal weed. Digital advertising giants like Google and Twitter aren’t open to sponsored search ads or tweets from small-business marijuana shops. Apple restricts that kind of content on its mobile app store. As a result, “potrepreneurs” will need to get creative in a hurry.

The entire industry is still exploring how to navigate the regulations —public policy and private-company restrictions— of marketing marijuana.
