I had this EXACT same line of thought this morning. Saw a story with a startling headline, clicked it, read it, saw the glaring obvious problem.

They are basically comparing several packs to one joint. WTF, really?

Aside from the obvious reason why its not comparable, its also not reasonable to assume that several-joint MJ smokers wont exist if MJ is legal. They don't exist now because its not legal and its not cheap.

This study is worthless. I understand the difficulty of finding incredibly-heavy MJ-users, but if they cant find those, then they should only compare what they've got to very light cigarette smokers who only light up a few times a month.
