To get back on topic here, I highly doubt any players smoke everyday. From my playing experience alone, junior, major junior and minors, I never once played with anyone who was a smoker. Lots of players chewed and that was kind of like a religious thing. Most of us would stick a dip in between periods.
The only time I encountered players smoking was after my "competitive" days were over. Playing in local senior leagues, seemed like all the washed up WHL or college guys became smokers.
Edit: Feel like I should mention that a lot of the guys would smoke when out drinking though. But never, when they weren't drinking.
