Cannabis-Associated Asthma and Allergies

Area of Science:

• Pulmonology
• Allergology
• Clinical Medicine

Background:

• Cannabis smoke inhalation is a common drug use method with potential for widespread pulmonary complications.
• The association between cannabis use and asthma or allergic conditions remains debated.
• Drug-induced pulmonary disease linked to cannabis warrants further investigation.

Purpose of the Study:

• To review existing evidence on the relationship between marijuana consumption and asthma or allergic diseases.
• To assess the impact of cannabis use on asthma and allergy symptom exacerbation and healthcare utilization.

Main Methods:

• Conducted a literature search of medical databases (English, Spanish, Portuguese) from January 1970 to March 2017.
• Utilized search terms including asthma, allergy, marijuana, marihuana, and cannabis.
• Performed a narrative review of retrieved studies.

Main Results:

• Several studies indicate a correlation between marijuana use and increased asthma and allergy symptoms.
• Evidence suggests marijuana use is associated with a higher frequency of medical visits for these conditions.
• Cannabis should be considered a potential trigger for acute asthma and allergic exacerbations.

Conclusions:

• Cannabis use may precipitate acute asthma and allergic attacks, necessitating its consideration in clinical practice.
• Further research is required to understand the long-term effects of cannabis on allergic asthma patients.
• Asthma and allergy patients are advised to avoid marijuana and be educated on associated health risks.
