Yoda, I'll take you up on the idea of discussing the size of the vape biz.

Vaping mj appears to be a relatively new method of pot consumption and while it may gain supporters that use pot, I doubt it is a very small market at this time.  Unfortunately, there is not any studies or seller data from their group to give any real sense of the issue.  I guess it really is a non-issue at this point in time.  Tia for the discussion.
