Cannabis Allergy: What do We Know Anno 2015

Area of Science:

• Allergy and Immunology
• Cannabis Science

Background:

• IgE-mediated cannabis allergy is increasingly recognized.
• Exposure to cannabis allergens can cause sensitization and allergic reactions.
• Cannabis sensitization may trigger secondary cross-allergies.

Purpose of the Study:

• To review the rising incidence of cannabis allergy.
• To describe the clinical manifestations and cross-reactivity patterns.
• To outline diagnostic and management strategies.

Main Methods:

• Literature review focusing on IgE-mediated cannabis allergy.
• Analysis of clinical presentations and cross-reactivity data.
• Summary of current diagnostic approaches and treatment.

Main Results:

• Cannabis allergy prevalence is rising, with varied clinical reactions.
• A
• cannabis-fruit/vegetable syndrome
• is described, involving cross-reactivity with plant-derived foods, tobacco, latex, and alcoholic beverages.
• Cross-reactivity is linked to shared allergens like lipid transfer proteins and thaumatin-like proteins.

Conclusions:

• Cannabis allergy is an emerging health concern with potential for severe reactions.
• Understanding cross-reactivity is crucial for diagnosis and management.
• Absolute avoidance of cannabis is the primary treatment strategy.
