A straw has never caused me any problems other than when using a paper straw it becomes soggy.
Well, I don't usually drink water out of straw. But when I drink water in the tumbler with straw, it feels like my water tastes 100 times better and feels more crisp.
I'm not sure if using straws as an adult can cause any problems. According to my research using straw can cause gas and bloating.
