A greener weed: the UK firm growing carbon-neutral cannabis

Glass Pharms hope its approach could show the way for all kinds of energy-intensive horticulture in the UK

For 26 years, Olivier Dehon worked in the corporate sector, ending up as chief financial officer for Xerox in the UK and Ireland before retiring four years ago. Last month he delivered his first consignment of high-strength cannabis.

Dehon’s dope is legal and above board, produced to supply the UK’s burgeoning market for medical cannabis on prescription. What’s more, Dehon and his colleagues believe it is the first carbon-neutral indoor weed grown anywhere in the world.
