My point was that I don't think there's a ton of productivity to be lost by smoking 1 puff in the middle of the night vs. smoking a whole joint in the middle of the day.
The "X" in this case has too wide of a range of interpretation to jump the gun on hypocrisy.
The problem is that, he said he wouldn't do X because he thinks it decreases productivity, and then goes and does X.
That's the problem
