Thanks for the response.
May I ask
A) In both screenings, both the police, and the independent one I commissioned, they mention "possible presence of benzodiazepines". Does the immunoessay test have a considerable false positive error rate? I take it must do as they will only say that a positive immunoessay test can only indicate a "possible presence", it cannot prove it, and that is why more detailed tests are needed.
B) I had some prescription valium about 3-4 weeks prior to the incident. Could this cause the immunoessay positive indication? however since it must have nearly been expelled from my system (I read somewhere it takes 23 days to be totally eliminated, based on its half life), then the more detailed test returned negative. i.e is it it possible for the immunoessay test to detect trace valium usage (a positive), but the more detailed test fails as it needs a higher concentration in my blood stream for a positive match.
C) I was seen by a police doctor about 6 hours after been arrested, who described me as being in an extremely impaired state. Are even large doses of Etizolam able to cause continued intoxication after 6 hours? I believe it is a short duration of action medication, so would it not have been more or less 'worn off' entirely after 6 hours?
D) Are there any medical explanations for unexplained loss of coordination and symptoms resembling intoxication? I took two etizolams several hours prior to the incident, and had been taking them at the same level for several months before without incident. I.e. Can i put forward an alternative explanation for my erratic behaviour, such as mental exhaustion, or anything else? Could you suggest some medical conditions that would have this effect
PS I understand I am asking for a significant level of detail, and I will of course reflect my gratitude in the tip I give you at the conclusion of our discussion.
