With respect to vaping products, the government has a consultation paper. They have regulatory authority. There should be some upper limit in nicotine products as to how much nicotine would be allowed. There's a different issue with respect to cigarettes. A proposal to take nicotine out of cigarettes is simply not viable in Canada. People smoke for the nicotine. It would functionally be the same as banning cigarettes, and in Canada we can't ban cigarettes.
