Cannabis against neuropathic pain

The study by Berman and his colleagues on 48 patients with neuropathic pain from damage of the brachial plexus already published as an abstract in the journal Anaesthesia in 2003 was now published as an article in the journal Pain.

Patients had received two different cannabis extracts in a double-blind crossover trial consisting of three 2-week periods. Both extracts decreased pain and improved sleep. The effects were moderate although mostly statistically significant.
