You may not be able to answer this, but if I understand correctly, you said that in CPIC it will say this is a schedule II offence. Item 1 of that schedule, natural cannabis and derivatives, is no longer an issue, but item 2, the synthetic cannabinoid receptor agonist, remains a criminal offence. Would the item number have been listed in CPIC in every case, because if not, we have an issue with figuring it out.
