Title: INHALATION OF VAPOUR OF THERAPEUTICAL SUBSTANCES, LIKE E.G. CANNABIS EXTRACT
Abstract:
A method of making a medicament which is a vapour comprising heating a composition to a temperature not exceeding 500 °C for a time of less than 10 seconds. The composition is non-volatile at 75 °C and generates a vapour free of pyrolysis products when heated in this way. The vapour is produced in a portion of air smaller than the mean respiratory tidal volume. A composition suitable for using in such a method is also disclosed.
