Thankfully at least a few Snohomish County divorce and custody lawyers are changing the outcome of the custody battles with a somewhat new test--the EtG/EtS (hereafter "EtG") hair alcohol test. The EtG hair test tends to show whether the test subject has been significantly intoxicated within the previous 90 days. The look-back period of 90 days is long enough to cast serious doubt on unfounded allegations.
Also good news, Snohomish County is gaining familiarity with the EtG hair test, and local courts often accept EtG hair results into evidence despite the test's newness. If you've been wrongfully accused of problem drinking in your Snohomish County custody battle, you probably want to consider submitting to this test.
