Manwhore, some places are still using ones that can not detect ETOH after 24hrs of use. Unfortunately, most government agencies, including Police and Fire have started using what is called an ETG
test which can detect alcohol metabolites up to a week from the last drink. Many Courts, Probation and Professional monitering agencies are using this now and it is becoming the Standard all over my neck of the woods. This is has been going on for about a year or so around here and it really has been getting people in a lot of trouble because of course they do not give you advance notice that they have started using these new tests. Be careful.
