Johan Obel and Clemens Boeninger run the Drug Store — the UK’s foremost and finest seller of CBD. And if you don’t know what CBD is, you soon will — the cannabis extract is behind one of the biggest new industries of this century, and it's being applied in a huge amount of treatments and supplements. The market around it, meanwhile, is predicted to be worth some $22 billion by 2022.

For two young guys, Johan and Clemens are annoyingly switched on, and their ideas around start ups are applicable to anyone interested in starting a business. Enjoy the episode.

Our thanks again to Mark's Club for playing hosts. Excellent olives.
