COVID-19 safety protocols for cannabis users
Because of increased risk of respiratory morbidity, clinicians advise that consumption of recreational cannabinoids be scaled back during the course of the pandemic. In light of conflicting news from several media outlets regarding the efficacy of cannabis intake with respect to COVID-19, preexisting users might unwittingly increase their consumption as a preemptive measure against being exposed to the infection. To prevent transmission among users, clinicians should discourage patients from sharing joints. This recommendation is thematically consistent with general precautionary measures about the dangers of sharing utensils, drinking cups/glasses, and so on, amid the pandemic.
Despite promising preliminary research results, CBD cannot be wholeheartedly recommended at this time; patients already on medically administered cannabinoids are urged to discuss the risk-benefit ratio with their respective health care clinicians. Cannabinoid therapies present a massive opportunity from the perspective of immunomodulation, especially when considering the prevalence of drug use. However, to improve clinical guidelines with respect to COVID-19 outcomes, it would be prudent to increase the overall volume of preclinical knowledge by gathering retrospective data (from case-control designs) and randomized prospective trials.
A more comprehensive list of advice from physicians concerning casual or chronic cannabis users may also include: adopting a dedicated delivery or dispensing system for cannabis products, making considerations for decontamination (i.e., disinfecting mouthpieces), ensuring cleansing precautions are maintained (washing thoroughly before and after use or procurement), switching to inhalation alternates (e.g., tinctures, edibles, and/or oils) to decrease further irritation to the lungs. For bong users, it is recommended that they apply rubbing alcohol to clean their device followed with a minute of air-drying.6
Conclusion
The literature from preclinical studies appears to largely favor the use of CBD, but there remains an element of uncertainty with respect to implementing cannabinoids for the treatment of coronavirus.
COVID-19 cannabinoid intervention is a hot topic with renewed interest from the industry and the public at large, but viral-focused therapies remain a relatively underused area worth exploring with case-control designs and randomized prospective trials. As cannabis legalization is picking up momentum across five additional states, the time is ripe to systematically investigate the therapeutic applications of the drug beyond merely preclinical data. Aside from educational reform initiatives, clinicians might proactively launch a platform that integrates telemedicine as well as digital apps, directly linking the patient to the clinician and monitoring the efficacy of program initiatives in real time.
