A review of cannabis allergy in the early days of legalization.

Cannabis allergy is a burgeoning field; consequently, research is still in its infancy and allergists' knowledge surrounding this topic is limited. As cannabis legalization expands across the world, it is anticipated that there will be an increase in cannabis use. Thus, we hypothesize that a concomitant rise in the incidence of allergy to this plant can be expected. Initiatives aimed at properly educating health care professionals are therefore necessary. This review presents the most up-to-date information on a broad range of topics related to cannabis allergy. Although the clinical features of cannabis allergy are becoming more well described and recognized, the tools available to make a correct diagnosis are meager and often poorly accessible. In addition, research on cannabis allergy is still taking its first steps, and new and potentially groundbreaking findings in this field are expected to occur in the next few years. Finally, although therapeutic approaches are being developed, patient and physician education regarding cannabis allergy is certainly needed.

Cannabis-related allergies: An international overview and consensus recommendations.

Cannabis is the most widely used recreational drug in the world. Cannabis sativa and Cannabis indica have been selectively bred to develop their psychoactive properties. The increasing use in many countries has been accelerated by the COVID-19 pandemic. Cannabis can provoke both type 1 and type 4 allergic reactions. Officially recognized allergens include a pathogenesis-related class 10 allergen, profilin, and a nonspecific lipid transfer protein. Other allergens may also be relevant, and recognition of allergens may vary between countries and continents. Cannabis also has the potential to provoke allergic cross-reactions to plant foods. Since cannabis is an illegal substance in many countries, research has been hampered, leading to challenges in diagnosis since no commercial extracts are available for testing. Even in countries such as Canada, where cannabis is legalized, diagnosis may rely solely on the purchase of cannabis for prick-to-prick skin tests. Management consists of avoidance, with legal issues hindering the development of other treatments such as immunotherapy. Education of healthcare professionals is similarly lacking. This review aimed to summarize the current status of cannabis allergy and proposes recommendations for the future management of this global issue.

Impact of cannabis knowledge and attitudes on real-world practice.

BACKGROUND: Increased cannabis consumption worldwide challenges allergists because of an upsurge in cannabis allergy and need to discuss cannabis with patients. OBJECTIVE: To determine the knowledge, attitudes, and practices regarding cannabis among allergists and their approach to recognizing and diagnosing suspected cannabis allergy. METHODS: The International Allergist Canna Knowledge, Attitudes, and Practices Survey was completed by members from 3 International Allergy Societies. Survey questions included the following: 13 on cannabis attitudes, 7 on cannabis knowledge, and 4 on real-world allergy practices. Knowledge level was dichotomized and Statistical Package for the Social Sciences TwoStep Cluster Analysis grouped participants by attitudes. Multivariate analysis determined the relationship of knowledge and attitude to practice delivery. RESULTS: Of 570 eligible surveys started, 445 (78.1%) were completed. Participants were 49.7% of female sex, 65.9% aged 24 to 56 years, approximately 70% in practice for more than or equal to 10 years, and 29.2% practicing in an area where cannabis use is illegal. Of the respondents, 43.1% reported consulting on patients with suspected cannabis allergy and 54.7% had undertaken skin prick testing, in vitro cannabis testing, or both. Statistically significant differences were found between the 3 societies for most variables analyzed. Analysis of attitudes revealed 3 clusters named Traditional, Progressive, and Unsure. Those with more progressive attitudes toward cannabis and who had more knowledge were more comfortable speaking to patients about cannabis and more often asked patients on how often and how they used cannabis (all P < .001). CONCLUSION: Varying knowledge and attitudes toward cannabis affecting comfort communicating with patients about cannabis were found in members of 3 allergy societies supporting the need for more cannabis research and education.

Cannabis attitudes and patterns of use among followers of the Allergy & Asthma Network.

BACKGROUND: Cannabis use in patients with allergy/asthma, a high-risk group for adverse effects to cannabis, is unknown. OBJECTIVE: To determine the patterns of use and attitudes toward cannabis in patients with allergy/asthma. METHODS: An anonymous online survey on cannabis attitudes and use was conducted through the Adult Allergy & Asthma Network. The Asthma Control Test assessed asthma burden. Cluster analyses determined group phenotypes and factor analyses condensed cannabis subjective effects into similar response patterns. RESULTS: A total of 88 of 489 respondents (18.0%) currently use cannabis with most at the age of less than 50 years old, of female sex, and of White race. Of the noncannabis users (N = 401), 2.5% reported cannabis allergy. Cluster analysis revealed that a liberal attitude toward cannabis was associated with current cannabis use (P < .001). Among current cannabis users, 40.9% of their physicians inquired on cannabis use; only 37.5% of users wanted to discuss cannabis. In addition, 65.9% used cannabis for medical or medical/recreational purposes. Cannabinoids used were tetrahydrocannabinol (33.0%), cannabidiol (19.3%), or both (47.7%). Smoked and vaped cannabis were reported by 53.4% and 35.2%, respectively. Furthermore, 51 cannabis users (58.0%) reported current asthma with 39.2% uncontrolled; of these, 50% smoked cannabis. Compared with current participants with asthma not using cannabis, those currently using cannabis experienced similar levels of asthma control, quality of life, and frequency of asthma exacerbations. Positive effects were endorsed more than negative effects to cannabis (P < .001). Moreover, 19.3% of cannabis users reported coughing that was associated with smoking cannabis (P < .001). CONCLUSION: Cannabis was used by less than 20% of the respondents with positive effects more frequent than negative effects. Half of cannabis users with uncontrolled asthma smoke cannabis, but only a minority of the physicians inquire about its use.

A Call to Commemorate International Holocaust Remembrance Day, January 27, in All Health Science Schools.

This viewpoint proposes why and how Holocaust Remembrance Day, January 27, should be honored in all health professions schools. A public letter, from which this viewpoint is adapted, has been endorsed by over 50 teachers of medicine, ethics, and history.

Teaching Health Professions Students About the Holocaust.

The legacy of health professionals' roles in the Holocaust is fundamental to understanding modern health care ethics, but teaching it is difficult. The University of Colorado Center for Bioethics and Humanities has developed a program that addresses 4 main pedagogical challenges of this content. This article identifies 3 core lessons and proposes 5 specific learning objectives related to health professionals' involvement in the Holocaust for any health professional training program.

Attitudes about cannabis mediate the relationship between cannabis knowledge and use in active adult athletes.

BACKGROUND: Little is known about how cannabis knowledge and attitudes impact cannabis use behavior. OBJECTIVE: To test the knowledge-attitudes-behavior paradigm in active adult athletes. DESIGN: The Athlete Pain, Exercise, and Cannabis Experience (PEACE) Survey, a cross-sectional survey study, used social media and email blasts to recruit participants and SurveyGizmo to collect data. PARTICIPANTS: Self-defined active adult athletes (n = 1161). MAIN MEASURES: Knowledge about cannabis was evaluated with four questions. Attitudes toward cannabis was evaluated with 11 questions. The attitudes questions were used in a TwoStep Cluster analysis in SPSS to assign group membership by attitudes. Chi-square was used to determine if there were differences in cluster membership by demographic factors and if knowledge about cannabis differed by cluster membership. Regression analysis was performed to determine if cannabis attitudes mediated the relationship between cannabis knowledge and cannabis use. KEY RESULTS: A three-cluster solution was the best fit to the data. The clusters were named Conservative (n = 374, 32.2%), Unsure (n = 533, 45.9%), and Liberal (n = 254, 21.9). There was a significant difference among the clusters for all 11 attitudes items (all p < 0.001). Attitude cluster membership was significantly different by age (p < 0.001), primary sport (p < 0.05), and knowledge about cannabis (p < 0.001). Athletes in the liberal cluster answered the knowledge questions correctly most often. Attitudes mediated the relationship between cannabis knowledge and cannabis use [Never (32.4%), Past (41.6%), Current (26.0%)] with athletes in the liberal cluster showing more knowledge and greater likelihood to be a current cannabis user (p < 0.001). Among current cannabis users there were differential patterns of cannabis use depending on their attitudes and knowledge; liberal athletes tended to co-use THC and CBD and used cannabis longer. (p < 0.001). CONCLUSIONS: Cannabis education needs to consider attitudes about cannabis, especially among those who might benefit from medical cannabis.

Cannabis: An Emerging Occupational Allergen?

Cannabis is the most commonly used psychoactive drug. In recent years, Cannabis access has expanded for both medicinal and non-medicinal has grown. This is also marked with an increasing number of individuals gaining employment in this emerging industry. In this article, we briefly discuss the health hazards associated with Cannabis exposure with an emphasis on the potential for allergic reactions in workers who handle and process Cannabis plant.

Occupational Allergies to Cannabis.

Within the last decade there has been a significant expansion in access to cannabis for medicinal and adult nonmedical use in the United States and abroad. This has resulted in a rapidly growing and diverse workforce that is involved with the growth, cultivation, handling, and dispensing of the cannabis plant and its products. The objective of this review was to educate physicians on the complexities associated with the health effects of cannabis exposure, the nature of these exposures, and the future practical challenges of managing these in the context of allergic disease. We will detail the biological hazards related to typical modern cannabis industry operations that may potentially drive allergic sensitization in workers. We will highlight the limitations that have hindered the development of objective diagnostic measures that are essential in separating "true" cannabis allergies from nonspecific reactions/irritations that "mimic" allergy-like symptoms. Finally, we will discuss recent advances in the basic and translational scientific research that will aid the development of diagnostic tools and therapeutic standards to serve optimal management of cannabis allergies across the occupational spectrum.

Clinical observations and seven-and-one-half-year follow-up of patients using an integrative holistic approach for treating chronic sinusitis.

CONTEXT: Despite the widespread popularity of alternative medical approaches to respiratory and allergic disorders, there is a lack of scientific substantiation of their benefits. OBJECTIVE: Assessment of the therapeutic benefit of an integrative holistic approach to the treatment of chronic sinusitis. DESIGN: Patients began a 5-month program consisting of 5 evening sessions of 2 hours each in October of 1999. SETTING: The program was held in the offices of one of the authors (WSS). PATIENTS: Ten patients of an allergist-immunologist specialist (WSS), symptomatic despite aggressive conventional treatment for their chronic sinusitis, were recruited to participate in an integrative holistic medical education and treatment program consisting of 5 sessions and evaluated at a 1-year follow-up. Sessions consisted of education in lifestyle and indoor-air modification, nasal hygiene, and treatment with fluconazole. Eight of 9 subjects were located and provided feedback 7 years and 6 months later, in June 2007. MAIN OUTCOME MEASURES: Health-related quality of life (QOL) was assessed using the short-form QOL survey (SF-12) and rhinitis QOL by the Rhinitis Quality of Life Questionnaire (RQLQ). RESULTS: No significant differences emerged in the SF-12 or mini-RQLQ scores comparing visit 2 with visit 1. Statistically significant improvement for physical and mental subscales of the SF-12 emerged comparing the results of visit 4 with visit 2 after the addition offluconazole treatment to the regimen, persisting through an additional year of follow-up. Feedback at 7.5 years confirmed marked long-term improvement in chronic sinusitis symptoms compared to their pre-study condition.

Age related differences in cannabis use and subjective effects in a large population-based survey of adult athletes.

BACKGROUND: There is a paucity of information regarding cannabis use behaviors in adult community-based athletes as most research in athletes has focused on misuse of cannabis in elite, adolescent, university-based athletes. We aimed to determine whether age related differences exist in patterns of cannabis use and subjective effects to cannabis in adult athletes. METHODS: The Athlete PEACE Survey used mainly social media and email blasts to recruit and SurveyGizmo to collect data. Cannabis patterns of use (duration of use, frequency of use, routes of administration, cannabinoid used, concurrent use with exercise), benefits, and adverse effects were reported. Age was reported by decade from 21 to ≥60. Age trends in cannabis use patterns and subjective effects were assessed using linear trend analysis. RESULTS: Of the 1161 participants, 301 (26%) athletes currently used cannabis. Younger athletes compared to older athletes reported significantly more positive and adverse subjective effects to cannabis, used cannabis longer, and used both tetrahydrocannabinol and cannabidiol for medical and recreational purposes. Younger athletes used cannabis concurrently with exercise more often than older athletes and consumed edibles, vaporized, and smoked more than older athletes. CONCLUSIONS: We found age-related cannabis patterns of use and subjective effects to cannabis. Concerns about cannabis mis-use and abuse in athletes maybe overstated with the potential benefits (improved sleep, decreased anxiety, less pain) outweighing the adverse effects (increased anxiety, increased appetite, difficulty concentrating).

Cannabis use in active athletes: Behaviors related to subjective effects.

Cannabis use has not been well characterized in athletes. Studies primarily examine problematic use or its categorization by anti-doping bodies as a banned substance. Patterns of use, reasons for use, and responses to cannabis consumption have not been studied in a community-based sample of adult athletes. The Athlete PEACE Survey examined cannabis use patterns and subjective effects to cannabis in a community-based cohort of adult athletes. We used mainly social media and email blasts to recruit and SurveyGizmo to collect data. 1,161 (91.1%) of the 1,274 athletes taking the survey completed it. Current cannabis use was evaluated by asking "In the past two weeks, have you used marijuana (including THC and/or CBD)?" and cannabis type used was assessed by asking "What do you primarily use THC, CBD, or both?". Cannabis benefits and adverse effects (i.e. subjective effects) and patterns of use were reported. 302 athletes (26%) currently use cannabis of whom 301 had complete data for cluster analysis. Cluster analysis was used to determine cannabis user phenotypes and exploratory factor analysis (EFA) was used to create subjective effects factors. Associations between cannabis user phenotype clusters and the subjective effects factors were explored using multivariate analysis. Cluster analysis identified three statistically distinct cannabis user phenotypes: (1) older athletes who primarily use medical CBD, (2) mixed age athletes who use cannabis mainly recreationally with both THC and CBD use, and (3) mixed age athletes who used cannabis the longest with primary THC and CBD use. EFA showed three subjective effects factors: (1) Well-being, (2) Calm, and (3) Adverse. Mean positive subjective were higher than mean adverse subjective effects (p<0.001). The cluster using THC and CBD showed the highest mean scores for all three subjective effects factors (p<0.001). Athletes who use a combination of THC and CBD exhibited the most benefit to well-being and calm with minimal adverse effects. Our methodology can be used to develop real-world evidence to inform future use of medical cannabis products.

Conducting an Integrative Health Interview.

Complementary medicine incorporates the use of non-evidence-based complementary modalities into conventional (Western) medicine. Alternative medicines are approaches that are used in place of conventional medicine. Integrative medicine is the synthesis of conventional medical treatments with "evidence-based" complementary medical practices. When complementary approaches are incorporated into mainstream health care, it is called integrative health (IH). Among children and adults, IH is common despite not all therapies being safe and/or effective. Clinicians have suboptimal knowledge of their patients' IH use because, in part, they do not know what questions to ask and/or do not have a standard intake form to collect an IH history, as recently demonstrated by an American Academy of Allergy, Asthma, and Immunology membership survey. To address this unmet need, a group of Complementary and Alternative Practice in Allergy Committee members and interprofessional collaborators reviewed the existing literature to locate IH history forms that could assist in identifying patients' IH use. When none was located, the group created 3 templates for the systematic collection and documentation of IH practices: 2 general screening surveys that could be given to patients to complete before an appointment and a third template that provides the clinician with open-ended questions to help uncover IH practices in culturally diverse patient populations. Specialists, already acknowledged as skillful interviewers, can expand their patient-centered expertise by developing their own IH competencies.
