Same, though it seems hard to determine just how risky it is. I have drank water from thin plastic bottles that had been sitting out in the sun and elements for a quite a while. I don't know exactly how long, probably a year or two. The water was gross! I attribute it to the plastic breaking down and contaminating the water, but that's just a guess.
