For me, mostly work issues. While I find pot is great for interpersonal relationship building, I've struggled with the following while smoking and running a startup:
* I can't prioritize tasks properly (both within work and outside e.g. fitness)
* I become passive as a leader, which isn't good leadership
* I evaluate situations based on emotional resonance rather than factual data
There are more, but those are the ones that immediately come to mind. These led to bad decisions, poor productivity, and ultimately hurting my trust with the team.
