Abstract

Cannabis use has increased over the last decade. At the same time, we see cannabis allergies appearing, ranging from simple rhinoconjunctivitis to anaphylactic-type reactions, some of which are severe since fatal cases have been described, but we also see allergic-induced food allergies cross-linked in the family of lipid transfer proteins (LTP). Indeed, cannabis contains an LTP called Can s 3. The LT are very widespread in the vegetable kingdom and are present in many vegetables and fruits. LTPs have a similar chemical structure and therefore cross-allergy is common. Thus, by becoming aware of the LTP of cannabis, it is possible to become allergic by a mechanism of cross-allergy to the other LTPs present in fruits and vegetables. This syndrome is referred to as cannabis-fruit-vegetable syndrome.
