Abstract Although increasing rates of cannabis use and cannabis use disorder (CUD) are well documented among veterans, little is known about their use of cannabis specifically for medicinal purposes. The present study characterizes such use and compares veterans reporting cannabis use for medicinal (n = 66) versus recreational (n = 77) purposes on (a) sociodemographic factors, (b) psychiatric disorders (posttraumatic stress disorder [PTSD], major depressive disorder [MDD], and CUD), (c) other substance use, (d) reasons for cannabis use and cannabis-related problems, and (e) physical and mental health. Participants were veterans deployed post 9/11/2001 recruited from a...

Abstract Background: The political climate around Cannabis as a medicine is rapidly changing. Legislators are adopting policies regarding appropriate medical applications, while the paucity of research may make policy decisions around conditions for which Cannabis is an effective medicine difficult. Methods: An anonymous online survey was developed to query medical Cannabis users about the conditions they use Cannabis to treat, their use patterns, perception of efficacy, and physical and mental health. Participants were recruited through social media and Cannabis dispensaries in Washington State. Results: A total of 1429 participants identified as medical Cannabis users. The most frequently reported conditions for which they used Cannabis were pain (61.2%),...

The benefits of medicinal cannabis (MC) can be maximized if clinicians educate patients about dosing, routes of administration, side effects, and plant composition. However, little is known about clinicians’ knowledge and practices in Washington State. Methods: An anonymous online survey assessed providers’ MC knowledge, beliefs, clinical practices, and training needs. The survey was disseminated through health care providers’ professional organizations in Washington State. Descriptive analysis compared providers who had and had not authorized MC for patients. Survey results informed the...

Abstract Background Regulatory changes are increasing access to both medical cannabis and cannabis in general. As such, understanding patterns of recreational and medical cannabis use is a high public health priority. Objectives Patterns of cannabis use (recreational and medical), other substance use, and psychiatric symptoms were characterized in a large sample of community adult cannabis users in Canada, prior to federal cannabis legalization. Methods This was a self-report assessment of 709 cannabis users (Mean age = 30.19 (11.82) years; 55.01% female). Patterns of overall substance use and psychiatric symptomatology were compared based on recreational/medical cannabis status. Results Overall, 61.4% of participants endorsed exclusively recreational use, while 38.6% reported some level of medical use. Of all medical...

However, little published data is known about the extent of medicinal cannabis use and the characteristics of patients using cannabis on doctor’s prescription. This study describes a retrospective database study of The Netherlands. Methods Complete dispensing histories were obtained of all patients with at least one medicinal cannabis prescription gathered at pharmacies in The Netherlands in the period 2003–2010. Data revealed prevalence and incidence of use of prescription cannabis as well as characteristics of patients using different cannabis varieties. Results...

Abstract Introduction Strong patient interest in the use of medicinal cannabis to treat various clinical indications has sparked global legislative changes. Practitioners are vital in implementing regulatory changes and facilitating patient access to medicinal cannabis, however, little is currently known about the factors influencing practitioners' uptake. Recent rapid increases in practitioner applications to prescribe medicinal cannabis in Australia provides a unique backdrop to examine the current factors influencing prescribing behaviours. This qualitative study examined Australian practitioners' perspectives on prescribing medicinal cannabis to provide a comprehensive exploration of the potential factors influencing uptake in clinical practice. Methods Seventeen semi-structured interviews were conducted with Australian health-care...

Abstract Cannabis is a plant that is cultivated worldwide, and its use is internationally regulated, but some countries have been regulating its medicinal, social, and industrial uses. This plant must have arrived in Peru during the Spanish conquest and remains widely cultivated illicitly or informally to this day. However, new regulations are currently being proposed to allow its legal commercialization for medicinal purposes. Cannabis contains specific metabolites known as cannabinoids, some of which have clinically demonstrated therapeutic effects. It is now possible to quantitatively measure the presence of these cannabinoids in dried inflorescences, thus allowing for description of the chemical profile or “chemotype” of...

Abstract Background Preclinical studies demonstrate that cannabinoid-mediated antinociceptive effects vary according to sex; it is unknown if these findings extend to humans. Methods This retrospective analysis compared the analgesic, subjective and physiological effects of active cannabis (3.56–5.60% THC) and inactive cannabis (0.00% THC) in male (N = 21) and female (N = 21) cannabis smokers under double-blind, placebo-controlled conditions. Pain response was measured using the Cold-Pressor Test (CPT). Participants immersed their hand in cold water (4 °C); times to report pain (pain sensitivity) and withdraw the hand (pain tolerance) were recorded. Subjective drug ratings were also measured. Results Among men, active cannabis...

Abstract Background Cannabis legalization has enabled increased consumption in older adults. Age-related mental, physical, and physiological changes may lead to differences in effects of cannabis in older adults compared to younger individuals. Objective To perform a scoping review to map the evidence regarding the health effects of cannabis use for medical and non-medical purposes in older adults. Methods Electronic databases (MEDLINE, Embase, PsycINFO, Cochrane Library) were searched for systematic reviews (SRs), randomized controlled trials (RCTs) and non-randomized/observational studies (NRSs) assessing the health effects and associations of cannabis use (medical or non-medical) in adults ≥ 50 years of age. Included studies met age-related inclusion criteria...

Abstract Purpose This study aimed to characterize the prevalence and correlates of cannabis use and the methods and reasons for use among recently diagnosed cancer survivors in a population sample within Washington state. Methods We identified individuals diagnosed with invasive cancers in the prior 6 to 17 months from April 2020 to December 2020 using the Seattle-Puget Sound Surveillance, Epidemiology, and End Results (SEER) cancer registry. Participants (n = 1,515) completed a questionnaire, including demographics, medical history, cannabis use, and other substance use. Cancer characteristics and date of diagnosis were obtained from SEER registry data. We calculated weighted prevalence...
