Never had a problem with blood shot eyes really, I usually bake my weed or stay outta sight until i dont look like I've been pouring salt into my eyes.

The only time I had to make an excuse was when i first started smoking it and my mom say my homemade waterfall bong made out of a soda bottle...and even though i wasstoned out of my mind from using it just minutes previously, I was thinkin on my feet and told her it was a water bottle rocket. She bought it.
