Cannabis: Miracle Medicine or Dangerous Drug? review – weeding out the truth

This documentary on the pleasurable highs and puritanical prejudices around cannabis use was lively and educational - even when its presenter got the munchies

It is the best and the worst time to have a documentary that requires you to balance two contradictory thoughts in your head; we are out of practice. We are a bit too mono, in everything, these days. But the latest instalment of the flagship science show Horizon, presented by the wisely chosen Javid Abdelmoneim - a doctor who wears his intelligence lightly and always looks to take the audience with him - encourages us to do so.

In Cannabis: Medical Miracle or Dangerous Drug? (BBC Two), Abdelmoneim disentangles the facts-so-far from the myths that have grown up around cannabis - and, since legislation changed last year, the over-the-counter products that contain it - with a view to discovering where he, as a doctor, should stand.
