Insomniacs who received nightly sublingual administration of a cannabinoid extract managed to get more and better sleep, suggests a new Australian study.
Investigators found that the extract was “well-tolerated and improves insomnia symptoms and sleep quality in individuals with chronic insomnia symptoms,” notes a study abstract, published online this month in Sleep.
Participants included those who had been experiencing chronic insomnia symptoms for at least three months. They received either the extract or a placebo over a two-week period.
Comparing the effects of the extract to a placebo, researchers considered self-reports from participants, measurements of sleep onset latency, wake after sleep onset, total sleep time and sleep efficiency, and self-reports of sleep quality and feeling rested upon waking. One person did not finish the study. The remaining participants, the vast majority of whom were female, did not report any serious adverse outcomes. There were, however, 40 mild, non-serious, adverse events — 36 of those involving subjects being administered the extract — “with all but one resolving overnight or soon after waking,” the study abstract reports.
