Bronchial asthma due to Cannabis sativa seed


C. Vidal, M.D., c/ Salvador Madariaga 35, 7°F, 15008 La Coruña, Spain


A 51-year-old man with asthmatic attacks due to Cannabis sativa seed inhalation was studied. Specific IgE against this seed was demonstrated by in vivo (skin and bronchial challenge tests) and in vitro methods (reverse enzyme immunoassay and histamine release from basophils), suggesting a Type I immunologic reaction.
