I don't know of all of the conditions that could have an impact, because this is not something that the alcohol test committee has ever been asked to study up until this point. Until we have time to study it and look more closely at all of the potential variables, we can't tell this committee what may or may not be a problem.
It's always going to be more difficult if you introduce environment into testing. If I have a person giving a sample directly into an approved screening device or directly into an approved instrument, I am not worried about the environment that person is standing in. I have a direct analysis of that individual's blood alcohol. Environmental factors are something else we just have to consider.
