Perhaps I can help clarify this issue.
Schedule 2 lists prohibited items. We will continue to add substances to that list. In addition to those prohibitions and in addition to the regulations that exist, the general prohibition is always there as that safety net and catch-all to deal with the dangers and the hazards that you're talking about. That's the whole purpose of the general prohibition: to allow the government to take that timely action if and when there is a substance of concern that is posing a danger to human health and safety. That is how it is structured.
