3.3. Professional Misconduct
C. The use of illegal substances is forbidden from the 2-minute warning until the player's scorecard is submitted. Such use shall result in immediate disqualification.
Nothing like that last bowl on your tee pad while waiting for the 2-minute warning... But like Jason stated, even with a medical exemption that is not legal in public. (Ron White: I was drunk in a bar, they THREW ME into public!) It's just not an immediate DQ...
