I've found that with high quality weed, my ability to hyperfocus on one thing and the durration that I'm able to maintain my focus intensifies significantly.

Sometimes it's really awesome.

Sometimes when I'd play City of Heroes, I'd accidently hyperfocus on only one member of a 5 or 6 person team that I was suposed to be healing. It would come as a complete and total shock when I realized that the entire team with the exception of that one person had been dead for quite some while. :rasta:
