In addition, Vaping
Products Labelling and Packaging Regulations require that a vaping product
containing nicotine display a nicotine concentration statement. This
statement must follow the specified format of “Nicotine – xx mg/mL”. In
most cases, this statement is required to be displayed on the main display
panel of the product or the package. For small products or products that
are not packaged, the information may be displayed on a tag.
Although the regulations do not specify a method for the determination of
nicotine concentration, the information displayed must not be false or
misleading. Health Canada has developed two laboratory methods that can measure
nicotine content across the full spectrum of nicotine concentrations in vaping
products currently on the Canadian market. These methods are available to
the vaping industry upon request.
The Product Safety Chemistry methods, which includes the nicotine methods, are
listed here: https://www.canada.ca/en/health-canada/services/consumer-product-safety/product-safety-testing/chemistry-methods.html.
The methods can be obtained on request by emailing CPS-SPC@hc-sc.gc.ca.
