Sure. In Colorado, we see a small portion of marijuana users who use only edibles, but the vast majority smoke. This goes for adolescents, high school students as well, in our surveys there. For the vast majority, their primary mode of use is smoking; we don't see a large portion using vaping or edibles.
The thought, as you may have alluded to was that it's easier to hide the latter and to be doing it during school, etc. Aside from a small number of cases, this isn't something that has been widespread.
