A popular internet site1 describes cannabis as “a leafy plant, the leaves and flowering tops (buds) of which may be either smoked or eaten. It also comes in a more concentrated resinous form called hashish, and as a sticky black liquid called hash oil”. It is said that users often report a pleasant “subjective enhancement of visual and auditory perception, sometimes with synaesthesia (sounds take on visual colourful qualities)” and the sense that time passes more quickly than real time, a “fatuous euphoria”, as well as relaxation and relief from stress.2
