Can a struggling British farm survive by growing one of the UK's most tightly regulated crops?
Medical cannabis in the UK is legal under prescription, but growing cannabis is tightly regulated and requires a Home Office licence. Clarkson couldn't just decide to grow it on Diddly Squat Farm without going through a very strict licensing process.
Some ideas that would fit the show:
Visit one of the UK's licensed medical cannabis growers to see how it's produced.
Explore whether British farmers could benefit from growing medical cannabis under licence, comparing profits with traditional crops.
Investigate the difference between industrial hemp and medical cannabis, since many people confuse the two.
Follow the bureaucracy involved in trying to obtain a licence, which is exactly the kind of red tape Clarkson often highlights.
Speak to patients who rely on prescribed medical cannabis and the doctors and companies involved in supplying it.
