I have never smoked and did start to feel a conflict when I wanted to use vintage tobacco cards to decorate my children's room. I was looking at the 19th century actress cards. I found myself opting for ones that already had the advertisement trimmed off.
The thing that makes it easier is I just am glad that the brands aren't still in business.
Also if there is a survey I use to be a bubble gum chewer but have quit and still collect gum (R-) cards. I do still eat caramel and chocolate candies and collect E cards as well. I do eat bread, ice cream, cereal, and other food but don't currently own any D- or F-cards. I use to read the newspaper and still do occasionally and do collect M- cards. I do not strip but own W- cards
