ABSTRACT
OBJECTIVE: Older adults represent the fastest growing demographic of cannabis users, and they endorse cannabis use for a variety of reasons including modulation of chronic pain, mental health symptoms, and sleep concerns. However, current evidence leaves questions of efficacy unanswered among these groups. Goals of the present study were to examine the hypothesis that medical cannabis (MC) use will, at the daily level, predict lower pain, depression, anxiety, and improved sleep.
METHOD: A final sample of 106 MC users were recruited nationwide (ages 55-74, 66.67% female, 82.86% white). A fully within-subject multilevel structural equation model was conducted with use patterns and symptomology broken into four temporal epochs. MC use, operationalized as subjective intoxication (Epoch 1), averaged across the day was used to predict subsequent pain, anxiety, and depression levels (Epoch 2), which were then used to predict sleep that night (Epoch 3), then subsequent pain, anxiety, and depression the following day (Epoch 4) prior to initiation of MC use.Results: Subjective intoxication predicted lower post-use pain, anxiety, and depression. Subjective intoxication is related to lower anxiety and better sleep the following night.
CONCLUSIONS: These findings provide evidence of momentary improvements in pain, anxiety, depression, and indirect benefits for sleep quality. In combination with other findings, the results advance our understanding of the efficacy and limitations of MC among older adults. Findings are limited by MC measurement and sample homogeneity (primarily White, non-Hispanic female). Future research should seek to further measurement of use and corresponding effects and examine expectancy effects in aging clinical populations.
