Among individuals with asthma and allergies who use cannabis, more than half said they aren’t willing to discuss their use of cannabis with their doctor and their doctor doesn’t ask, according to recent research at the annual meeting of the American Academy of Allergy, Asthma, and Immunology, held virtually this year.
In an online survey of respondents with asthma and allergies in the Allergy & Asthma Network, 88 of 489 (18.0%) reported cannabis use. Of these respondents, 37.5% said they wanted to discuss their cannabis use with their doctor, 51.1% said they would not want to, and 11.4% reported they were unsure. In addition, 40.9% of respondents said their doctor inquired about cannabis use, while 51.1% said their doctor did not bring up cannabis use at all, either through a verbal discussion or on an intake form.
To date, there has not been much research on use of cannabis among patients with allergies and asthma, Joanna S. Zeiger, MS, PhD, of the Canna Research Foundation in Boulder, Colo., said in her presentation. “This is a group with whom route of administration could have broad adverse effects. Smoking or vaping cannabis in this population could lead to increased symptoms of cough and wheeze, as well as increased use of asthma medications and exacerbations of their disease.”
Dr. Zeiger and colleagues recruited 489 respondents for the AAN Pain, Exercise, and Cannabis Experience Survey study through social media channels between May 2020 and September 2020. In the survey, the researchers asked questions about the nature of the respondent’s cannabis use (medical, recreational, or both), the types of cannabinoids used (tetrahydrocannabinol [THC], cannabidiol [CBD], or both), the route of administration (capsule, edible, oil/tincture, smoke, spray, topical, or vaporizer), and subjective effects. Most of the respondents reported using both THC and CBD, with smoking, edibles, and vaping being the most comment route of administration.
Of the 88 respondents who said they currently used cannabis, 60.2% were aged less than 50 years, 72.4% were women, and 71.6% were White. A majority of respondents had been using cannabis for 3 or more years (54.5%) , used it less than one time per day (60.2%), and used it for pain (68.2%). Current asthma was reported in 51 respondents (58.0%), and 39.2% had uncontrolled asthma. Half of those respondents with uncontrolled asthma reported smoking cannabis, and 25.0% reported coughing because of cannabis. Both THC and CBD were used by 47.7% of respondents; 33% reported THC use alone, while 19.3% used CBD alone.
Reported effects of cannabis use
The most common positive effects of using cannabis reported among respondents were that it helped with sleep (66 respondents), calmed them down (60 respondents), reduced pain (60 respondents), or decreased anxiety (59 respondents). Many respondents who reported positive effects were using both THC and CBD. For example, respondents who reported using cannabinoids for calming, 46.7% reported using both, compared with 36.7% who used THC only and 16.7% who used CBD only. Among respondents who reported that cannabis helped them sleep, 51.5% used both THC and CBD.
Regarding adverse effects, there were no significant differences based on use of THC or CBD, but 31.9% of respondents who said they smoked cannabis and 4.9% of respondents who used cannabis through a route of administration that wasn’t smoking reported they coughed with their cannabis use (P < .001). No respondents reported anaphyalaxis, although, among individuals who did not use cannabis, 2.5% reported a cannabis allergy.
‘Cannabis allergy is real’
Commenting on the research, Gordon L. Sussman MD, allergist, clinical immunologist, and clinical professor of medicine at the University of Toronto, said the survey is a thorough questionnaire that is likely representative of attitudes about cannabis in the United States and countries where cannabis is not broadly legalized.
Cannabis allergy, however, is not uncommon, and “is something that people should be aware of,” he said. “Cannabis IgE allergy is real, is probably fairly common, and is something that [clinicians] should be asking about routinely.”
One limitation of the research was not knowing the number of people who declined to answer the survey, as there may be a bias in the results toward people who want to answer the questions, compared with those who did not want to answer. “When you do a survey, only a certain number of people are going to answer, and [you also want input from] people that don’t answer,” Dr. Sussman said.
Dr. Sussman acknowledged it can be difficult to get patients to admit cannabis use, even in countries like Canada where it is legal. Surveys like the one administered by Dr. Zeiger and colleagues are “the first step” to getting updated assessments of cannabis attitudes and recommendations. “The next step is doing an international survey, so you get different countries’ viewpoints and perspectives,” he said.
This study was supported by the Allergy & Asthma Network and the Canna Research Foundation. Three authors are affiliated with the Canna Research Foundation. Dr. Sussman reported no financial conflicts of interest. Dr. Sussman participates in the International Cannabis Allergy KAP Collaboration, a group founded by one of the coauthors, William Silvers, MD, but Dr. Sussman was not involved with this study.
