Terpenes in their normal concentrations as used throughout the whole plant and in the production of whole-plant products, are considered to be among the lowest risks compared to those concentrated into smaller amounts or made with inferior quality materials. Inhaling large amounts of these compounds could contribute to airway irritation and nausea, while for some individuals, consuming these products may lead to gastrointestinal discomfort (upset stomach). The amount consumed and the purity of the material will be the most important determinants in how these compounds will affect an individual's body.
