Amber Drinking Glasses

Is it something in amber that might leak into the cold or hot water (or other liquid), which would render it unfit for consumption?

Links to web pages with the answer / s will be greatly appreciated!

I think a jar of amber glass must be perfectly safe to use for drinking. We use amber glass jars all the time to collect water samples for environmental analysis because they do not react with anything, or anything in the leaching of samples and they protect the UV light which could break the chemicals in the samples.
