Megan is a health and wellness advocate, and cancer survivor, who knows first hand the medicinal benefits of CBD products.  She has enjoyed a long career in hospitality and customer service and has worked in the cannabis space with producers, processors, and retailers.  She brings insight from working with medical patients and recreational customers alike.  Her goal is to continue to educate people on the use of CBD.


We are passionate about the healing potential of cannabis and the promise of blockchain.  The dis-intermediation and decentralized nature of distributed ledger technology is a natural fit for "gray markets" and is helping support those on the forefront of the wave of legalization sweeping the globe.

We are proud to have a role in supporting this transformation and see it as a harbinger of both greater freedom personal freedom and direct-to-consumer transactions. 

Envisioned as a means of pricing as well as a proxy for the "spot price" of cannabis extracts, Cannabium is evolving thanks to the team behind it and while functioning as a means of payment for online cannabis transactions, is now positioned to be recognized for what it represents: quality products at great prices.
