I wish I understood their logic.  They say that they want to make sure that vaping is accessible to adult smokers, and I believe them, but this bill removes important characteristics that make vaping successful. Every vaper I know has a collection of different flavours, because adults like fruit, candy and dessert as much as young people, but this bill would ban such flavours.  Vaping has spread quickly through word of mouth and Facebook, but the bill would make it a criminal offense to say that it's safer and more pleasant than smoking. They say that they want to make sure that Canadian regulations reflect science, but ignore much of the international research showing that vaping is vastly safer than smoking to both the individual and his/her surroundings and that vaping is not proving to be a gateway to tobacco. 
Every senator and every MP should be required to visit a vape shop and learn some basic facts before voting on Bill S5 -- they owe it to the Canadian public.
