Meet our Medical Advisory Board

CannaCraft’s main goal for all our brands is to create the safest and most effective cannabis products possible. As one of the largest vertically integrated cannabis companies in the country CannaCraft is also uniquely position to make meaningful, positive changes towards improving cannabis education, research and honing-in on the most effective formulations to elicit targeted effects. However, we realize that for the best outcomes we need to actively seek advice from experts with diverse perspectives – to make the best products we need to work with the best people!

This thought is what led to the creation of CannaCraft’s Council of Cannabis Clinicians (CCCC). The CCCC engages in direct dialogue with CannaCraft’s in-house scientists, executive leadership team and Board of Directors. It gives us an avenue to learn more about the patient experience with cannabis products and provides guidance about how we can continually improve our brand’s products and ourselves to be the best that we can be.

Our CCCC members were all hand-picked as experts in diverse disciplines of cannabis science and medicine. Please, meet our members!
