There was a clinical study done where a group of nurses who claimed to be sober were tested under closed clinical conditions.
These nurses claimed they were sober but were testing positive. Under this test one group Non-alcoholic was used as a control. The othergroup were hospitalized to prevent used of alcohol but used WHC ten times a day. They tested positive ofr ETg a metablolite of alcohol produced by the liver.
There are a huge number of false positive for Etg when nurses use WHC.so much so that nurses in monitoring programs are told to avaid WHC by their monitoring boards.
There are clinical studies to show this.
Have a happy Easter
