Initial experiences with medicinal extracts of cannabis for chronic pain: Results from 34 ‘N of 1’ studies
Three Cannabis Based Medicinal Extracts ( CBMEs ) for sublingual use became available in 2000 . A total of 34 ‘ N of 1 ’ studies were undertaken using this novel therapy for patients with chronic , mainly neuropathic , pain and associated symptoms to explore efficacy , tolerability , safety and dosages . Three CBMEs ( Δ9 Tetrahydrocannabinol ( THC ) , Cannabidiol ( CBD ) and a 1 : 1 mixture of them both ) were given over a 12‐week period . After an initial open‐label period , the CBMEs were used in a r and omised , double‐blind , placebo controlled , crossover trial . Extracts which contained THC proved most effective in symptom control . Regimens for the use of the sublingual spray emerged and a wide range of dosing requirements was observed . Side‐effects were common , reflecting a learning curve for both patient and study team . These were generally acceptable and little different to those seen when other psycho‐active agents are used for chronic pain . These initial experiences with CBME open the way to more detailed and extensive studies
