Agree. I also think the view on substances is generational. People 50yrs and older grew up with targeted ad campaigns saying how cannabis made you crazy, lazy and potentially a serial killer hahaha. Of course, in this day and age, we all know who was behind those campaigns, as it has been exposed, but the residue is still present.
Overall, for me it goes back to enjoy whatever you'd like on the course as long as you keep pace of play and don't affect anyone else on the course. Most importantly, don't become impaired to the point where you can't legally drive your car home at the end of the round.
