I used to get busted at work when I went in stoned. I used to work at Wal-Mart many years ago, I was 16 and I had to hide my red eyes. I go into work and people said my eyes got glazed over, and were whiter than hell! They knew I was stoned, so after that, I never used it again.

That was Visine I used at the time. It turned my eyes glazy and really, really white.
