Sleep disturbances have been linked to multiple maladaptive outcomes including mental health consequences, increased risk of medical conditions, and cognitive performance deficits. While improvements in sleep have been a motivation behind cannabis use, research is largely inconsistent regarding the relationship between cannabis and sleep. In a recent study, it was found that currently using cannabis was associated with worse subjective sleep quality. A higher frequency of edibles use was also associated with worse subjective sleep efficiency, lower sleep duration and quality. Having higher CBD concentrations also led to better sleep efficacy and duration, although this was significantly affected by age with older adults seeing the largest effect.
