As someone who has lost loved ones to smoking, I wish we never had cigarettes because they are killers. And almost every smoker will tell you they wish they had never started smoking.
So when countries start banning tobacco, this will be an easy ban for a lot of people to get behind.
That's why they are starting with tobacco. This isn't about banning tobacco, it's about SETTING THE PRECEDENT that its acceptable to ban products.
It's a very slippery slope when it comes to trading in your rights and freedoms for what makes sense in the moment.
