Sickle Cell Riddim 

www.scsgghana.org
Sickle Cell Disease is a blood related genetic disorder which affects black people. Reggae music, even though made by all peoples, is made and consumed mostly by black people. That is why Debbie Dibble had this riddim made in hopes that other reggae artistes jump on it, there by helping spread awareness on the condition.
One doesn't necessarily have to make a song about Sickle Cell Disease with the riddim...Just keep the title of the riddim in the title of your song to support the creation of awareness
