We've worked for a number of years to control the size of tobacco packaging, starting in the early 1990s. We had kiddie packs banned—they were packs of five cigarettes—largely because they were affordable to youth, not because of the size per se.
I think that may be a consideration in the future. How large the package on the market ends up being will be largely determined by how much it costs, and if it's too expensive, consumers won't buy it. Packages of individual joints, for example, may be affordable and attractive to youth, so I think that needs to be monitored over time. There should be some regulatory flexibility to further restrict packaging sizes if it becomes necessary.
