If you’re trying to switch to a lower nicotine or tar option, you don’t really have a way to compare or even know what’s available anymore.

Most people that look to quit smoking typically don't change brand, instead they cut back or switch to an alternative like vaping, patches or gum.

As an adult, should you actually have the right to see what legal products are available before buying them?

No, I don't think knowing what tobacco products a store carries should be a right. If you're not sure, you can just ask the person behind the counter. They'll tell you.

Most smokers I know buy the same brand every time and have never switched.
