Do crystal light iced teas have caffeine?

I drink raspberry tea that I bought for my daughter who is pregnant. It tastes great, and I certainly did not notice any caffeine from drinking it. It's highly recommended for pregnant women so I don't think it would have much caffeine. I looked on a website that usually has all foods listed, but I didn't find raspberry tea. Still, it's a cool link. http://www.nal.usda.gov/fnic/foodcomp/search/index.html I bought my tea online from the bulkherbstore: http://www.bulkherbstore.com/RRLC
