Crushballs are small flavor capsules that can be added to cigarettes or rolling tobacco to add a burst of flavor. They exist in the UK as an alternative for smokers who want to add a burst of flavor to their smoking experience, without having to switch to flavored cigarettes or rolling tobacco.
In the UK, flavored cigarettes and rolling tobacco were banned in May 2020. However, crushballs are still legal because they do not change the composition of the cigarette or tobacco, and therefore do not fall under the ban on flavored tobacco products.
