Review Meta Analysis
Efficacy, tolerability and safety of cannabis-based medicines for cancer pain : A systematic review with meta-analysis of randomised controlled trials.
The importance of medical cannabis and cannabis-based medicines for cancer pain management needs to be determined. ⋯ Very low quality evidence suggests that oromucosal nabiximols and THC have no effect on pain, sleep problems and opioid consumption in patients with cancer pain with insufficient pain relief from opioids. The complete manuscript is written in English.

The law on the amendment of the narcotics law and other regulations, which was accepted by consensus by the German Parliament, significantly expanded the options for the use of cannabis-based medicinal products. In individual cases, already approved cannabis-based medicinal products can also be prescribed outside the approved indication at the expense of the statutory health insurance funds (GKV). The cost of treatment with cannabis flowers and extracts as well as dronabinol, which are not approved under the drug law, will also be covered by the GKV upon application. ⋯ In addition, physicians are obliged to participate in an accompanying survey. To this end, they must send data to the Federal Institute for Drugs and Medical Devices providing information about treatment with cannabis-based medicinal products. When prescribing medical cannabis products as defined in the Act of 6 March 2017 amending the law on narcotic drugs and other regulations, physicians assume a special responsibility that goes far beyond the responsibility for the use of authorized finished medicinal products.

An online questionnaire about cannabis medication (CAM) was sent to German pain therapists 1 year after the introduction of the new act "Amendment to drug and other regulations" of 06.03.2017. ⋯ The study shows an information deficit in knowledge and handling of selected CAM among physicians. Given the high rejection rate, there may also be a knowledge gap on the side of the health insurances. From a certain number of patients upwards, the non-interventional accompanying survey required by law was deemed to be barely practicable from both a time and an economical point of view.

In Germany, physicians who prescribe cannabis-based medicines at the expense of the statutory health insurance are obliged to take part in an accompanying survey. Pain was the most commonly reported diagnosis, making an interim evaluation for the indication of pain feasible. ⋯ Physicians should comply with their legal obligation to participate in the accompanying survey. Pain is by far the most common diagnosis in cannabis drugs. For about one third of these patients, physicians reported a clear improvement in pain. Due to the amount of data hitherto and the limitations in the accompanying survey, the results should not be overinterpreted in terms of efficacy and should always be related to existing reviews. The lower age and higher proportion of men among patients treated with cannabis flowers were remarkable. At 37.6%, the overall drop-out rate was high. The most frequent side effects related to vigilance and are therefore highly relevant in terms of driving ability, work ability and risk of falling. For a differentiated evaluation of treatment success, more data needs to be available.
