To mark World Water Day, on March 22nd Solidarités International and its agency BDDP Unlimited will roll out a campaign to build awareness of the scourge of undrinkable water.

The proliferation of marijuana edibles for both medical and recreational purposes is giving rise to a cottage industry of baked goods, candies, infused oils, cookbooks and classes that promises a slow burn as more states legalize the practice and awareness spreads about the best ways to deliver the drug. Edibles and infused products such as snack bars, olive oils and tinctures popular with medical marijuana users have flourished into a gourmet market of chocolate truffles, whoopie pies and hard candies as Colorado and Washington legalized the recreational use of marijuana in the past year.
