Cannabis is widely used for chronic pain. However, there is some evidence of an inverse dose–response relationship between cannabis effects and pain relief that may negatively affect analgesic outcomes. In this cross-sectional survey, we examined whether daily cannabis use frequency was associated with pain severity and interference, quality of life measures relevant to pain (eg, anxiety and depressive symptoms), and cannabis use preferences (administration routes and cannabinoid ratio). Our analysis included 989 adults who used cannabis every day for chronic pain. Participant use was designated as light, moderate, and heavy (1–2, 3–4, and 5 or more cannabis uses per day, respectively). The sample was also subgrouped by self-reported medical-only use (designated MED, n = 531, 54%) versus medical use concomitant with a past-year history of recreational use (designated MEDREC, n = 458, 46%). In the whole sample, increased frequency of use was significantly associated with worse pain intensity and interference, and worse negative affect, although high-frequency users also reported improved positive affect. Subgroup analyses showed that these effects were driven by MED participants. Heavy MED participant consumption patterns showed greater preference for smoking, vaporizing, and high tetrahydrocannabinol products. In contrast, light MED participants had greater preference for tinctures and high cannabidiol products. Selection bias, our focus on chronic pain, and our cross-sectional design likely limit the generalizability of our results. Our findings suggest that lower daily cannabis use frequency is associated with better clinical profile as well as lower risk cannabis use behaviors among MED participants. Future longitudinal studies are needed to examine how high frequency of cannabis use interacts with potential therapeutic benefits. Perspective Our findings suggest that lower daily cannabis use frequency is associated with better clinical profile as well as safer use behaviors (eg, preference for cannabidiol and noninhalation administration routes). These trends highlight the need for developing cannabis use guidelines for clinicians to better protect patients using cannabis.

Cannabis is commonly used to manage chronic pain, but cannabis use patterns among individuals with chronic pain, has not been well-characterized. We report cannabinoid, administration route, and product selection preferences among medical cannabis users with chronic pain from an ongoing, online survey. We also examined whether these preferences are affected by differences in sex, intentions behind use (medical only [MED] vs medical + recreational [MEDREC]), and experience with cannabis (novice:1 year vs experienced: ≥1 year). The survey was completed by 1,321 participants (59% female) 76.5% of whom used cannabis every day. 93.4% used 2 or more administration routes and 72.5% used 3 or more. Female, MED, and novice users were less likely to smoke or vaporize (all P.0001), but more likely to rank edibles, tinctures, and topicals as a first-choice administration route than their counterparts. Female and MED users also preferred low THC: high cannabidiol ratios significantly more than their counterparts. Overall, only 2.6% of participants selected cannabis products with input from a medical professional, although 54.9% relied on advice from dispensary employees. More male, MEDREC, and experienced users selected products based on factors that reflected greater comfort with cannabis (eg, smell, visual properties, cannabis variety). The wide variability in cannabis use among these different groups indicates the need for further research to investigate how specific use routines relate to clinical outcomes. PERSPECTIVE: Medical cannabis users with chronic pain show distinct differences in cannabinoid preferences and administration associated with user sex, intentions behind use, and experience with cannabis. This article highlights the wide variability in cannabis preferences among medical cannabis users with chronic pain, which may be relevant for clinical outcomes.

Objective Moderate alcohol consumption has been associated with improved health outcomes including reduced risk of heart disease; however, less is known regarding alcohol's effects on chronic pain. The aim of this study was to assess associations between pain, fibromyalgia symptoms, and moderate alcohol use in a large chronic pain sample. Methods A total of 2,583 new chronic pain patients presenting at a university pain clinic reported alcohol use and completed validated measures; 592 (23%) patients reported drinking, with 502 (85%) classified as moderate drinkers (females ≤7 and males ≤14 drinks/wk). General linear models (GLM) assessed the effects of moderate drinking on pain and symptom outcomes. The sample was stratified by gender and fibromyalgia (FM) status in secondary analyses. Results Moderate alcohol users reported significantly lower FM symptoms (widespread pain and symptom severity), pain severity, interference, anxiety, depression, and catastrophizing, and they reported higher physical function. Similar findings were observed in gender-stratified analysis, minus associations with FM symptom severity in females and anxiety in males. In patients meeting FM criteria, moderate drinking was associated with lower pain severity, interference, and depression, and higher physical function. Results in non-FM patients were similar to the total sample. Conclusions Moderate alcohol consumption in chronic pain patients was associated with decreased pain severity and interference, fewer painful body areas, lower somatic and mood symptoms, and increased physical function. A similar effect was observed in non-FM patients, but to a lesser extent in FM patients, suggesting chronic pain patients with less centralized forms of pain may benefit most from moderate alcohol consumption.

Chronic pain is common, costly, and challenging to treat. Many individuals with chronic pain have turned to cannabis as an alternative form of pain management. We report results from an ongoing, online survey of medical cannabis users with chronic pain nationwide about how cannabis affects pain management, health, and pain medication use. We also examined whether and how these parameters were affected by concomitant recreational use, and duration of use (novice:1 year vs experienced: ≥1 year). There were 1,321 participants (59% female, 54% ≥50 years old) who completed the survey. Consistent with other observational studies, approximately 80% reported substituting cannabis for traditional pain medications (53% for opioids, 22% for benzodiazepines), citing fewer side effects and better symptom management as their rationale for doing so. Medical-only users were older (52 vs 47 years old; P.0001), less likely to drink alcohol (66% vs 79%, P.0001), and more likely to be currently taking opioids (21% vs 11%, P.0001) than users with a combined recreational and medical history. Compared with novice users, experienced users were more likely to be male (64% vs 58%; P.0001), take no concomitant pain medications (43% vs 30%), and report improved health (74% vs 67%; P = .004) with use. Given that chronic pain is the most common reason for obtaining a medical cannabis license, these results highlight clinically important differences among the changing population of medical cannabis users. More research is needed to better understand effective pain management regimens for medical cannabis users. Perspective: This article presents results that confirm previous clinical studies suggesting that cannabis may be an effective analgesic and potential opioid substitute. Participants reported improved pain, health, and fewer side effects as rationale for substituting. This article highlights how use duration and intentions for use affect reported treatment and substitution effects.

Background Patients are commonly provided tools in the hospital to overcome poor sleep. Whether education on use of sleep tools can impact health outcomes from a patient perspective is not known. Methods We recruited 120 adults admitted to a nonintensive care unit cardiac-monitored floor. All patients received a set of sleep-enhancing tools (eye mask, ear plugs, and a white noise machine) and were randomized to receive direct education on use of and benefit of these sleep-enhancing tools (intervention), or an equal amount of time was spent discussing general benefits of sleep (control). Measurement of several symptom domains was assessed daily by health outcome survey responses, and change from baseline was assessed for differences between groups. Inpatient opioid use and length of stay were also measured. Results Participants randomized to receive the education intervention had a significantly greater decrease in fatigue scores over the 3 days, compared with controls (5.30 ± 6.93 vs 1.81 ± 6.96, t = 2.32, P = .028). There was a trend toward improvements in multiple other sleep-related domains, including sleep disturbance, sleep-related impairment, physical functioning, pain severity, or pain interference (all P >.140). There was no difference in length of stay between intervention and control groups (7.40 ± 7.29 vs 7.71 ± 6.06 days, P = .996). The change in number of opioid equivalents taken did not differ use between the groups ( P = .688). Conclusion In a randomized trial of education in the use of sleep-enhancing tools while hospitalized, patient fatigue was significantly improved, whereas several other patient-reported outcomes showed a trend toward improvements. Implementation of this very low-cost approach to improving sleep and well-being could substantially improve the patient care experience.

Date Presented 4/8/2016 Simple sleep-enhancing education can significantly improve perceptions of sleep quality, wake disturbance, and fatigue in hospitalized adults. Occupational therapists have the opportunity to implement this education in their daily roles. Primary Author and Speaker: Steven Heidt Contributing Authors: J.
