I have met two judoka who smoke. They reek when you get close to them :(

yes, i can smell it off of them. One was a beginner that ultimately quit training after he couldn’t give up smoking and would gas out at every shiai. The other is a french guy who trained since he was 5, he relied a lot on his precise timing, foot sweeps and positioning so he didn’t need to move much.

Many. Including high level players (although there are definitely fewer smoking players at the high level than there used to be).

I don’t smoke wit cigarettes but my partner does. They don’t smell like cigarettes unless they just smoked one. Granted they never smoke indoors.

Personally I take a quick shower before class and my gi always smells like laundry detergent. So even if I did smoke before I left for class I doubt anyone would smell it.
