Abstract
Cannabis is a narcotic substance derived from the hemp plant (Cannabis indica or Cannabis sativa), and a range of derivatives and extracts are known. An aerosol of cannabis can be made by vaporising cannabis at an elevated temperature, causing the cannabis vapour to flow to a region at lower temperature at which the vapour would be supersaturated, generating seed nuclei of particle size less than 0.5 .mu.m, and mixing the seed nuclei with the vapour. Heterogeneous nucleation occurs due to the seed nuclei, so that droplets of a desired diameter and concentration can be obtained. The seed nuclei may for example be derived by passing air over molten sodium chloride.
