The cannabis itself obviously has a number of compounds, as has been alluded to earlier, THC being the psychoactive one. CBD is another compound found in cannabis that has a non-psychoactive effect. The question is, can people produce or sell cannabis with other adulterants in it? Yes, of course they can.
In terms of how the potency of THC is presented in any cannabis sample versus CBD ratios, that again is going across the board. As we've seen, there has been a general increase certainly in a lot of street cannabis towards a higher level of THC, which is the psychoactive element, which does then precipitate some of the greater risks and harms we've seen.
