Hemp Seed Awareness Allergy Study at University Hospital, Angers

What this Trial Is About

Researchers are investigating allergies related to hemp seed, a product derived from the Cannabis sativa plant that contains high levels of cannabidiol (CBD) but very low levels of tetrahydrocannabinol (THC). Hemp seed allergies are less studied compared to recreational cannabis allergies, though hemp seeds can cause severe allergic reactions such as anaphylaxis, especially in individuals previously sensitized through skin or respiratory exposure to cannabis. This study aims to better understand the allergenic potential of hemp seeds in people referred to the Allergology Unit. The study involves performing a diagnostic prick-test using hemp seed and flower extracts to detect allergic reactions. Participants will undergo this prick-test on Day 1 to assess skin reactivity to hemp. The study also collects information about participants' history of hemp use to explore possible sensitization routes. No drug or treatment is given as this is an interventional diagnostic study. Participants will be adults referred for allergy testing at the Hospital of Angers, who will have the prick-test performed and their medical and exposure history recorded. Researchers will monitor the results of the prick-test and document any signs of allergy. The primary measure is a positive prick-test response on the first day. The study focuses on safety and accurate allergy identification, with participation involving a single visit for allergy testing and history taking.
