Harvard is honoring singer Rihanna as the university's 2017 Humanitarian of the Year. Although best known for singing songs like 'Work' and 'Diamonds', Rihanna is heavily involved in humanitarian causes.

“Rihanna has charitably built a state-of- the-art center for oncology and nuclear medicine to diagnose and treat breast cancer at the Queen Elizabeth Hospital in Bridgetown, Barbados,” Harvard Foundation Director S. Allen Counter said in a statement. "She has also created the Clara and Lionel Foundation Scholarship Program [named for her grandmother and grandfather] for students attending college in the U.S. from Caribbean countries, and supports the Global Partnership for Education and Global Citizen Project, a multiyear campaign that will provide children with access to education in over 60 developing countries, giving priority to girls and those affected by lack of access to education in the world today.”

The Bahamian star is also one of the most visible cannabis consumers in America today and a legalization advocate. And by demonstrating that you can enjoy a puff and still achieve great success - including 8 Grammy awards and numerous multi-platinum albums on top of the Harvard Humanitarian award --Rihanna challenges the lingering stigmas and stoner stereotypes associated with cannabis use.

And mary jane repays the favor by giving Rihanna plenty of musical inspiration.
