Primary Outcome Measures
NameTimeMethod
Psychometric test pre and post exposure.<br>(Composite Primary Outcome)<br><br>(1)Complex Reaction time test: Reaction time measured to the identification of a simple object.<br>Example: Picture of a dog with the word DOG next to it. True/False option with the reaction time to answer masured. <br><br>(2)Balance test scored to 10<br>stand with feet together =2<br>arms at 90 deg from side =2 <br>bend one knee to 90 deg = 2<br>look up =2<br>close eyes =2<br><br>Loss of 1 point for loss of balance with correction<br>Loss of 2 points with loss of ballance without correction[*pre exposure for baseline<br>*post exposure immediately and at 60min (correlates with maximum plasma level)]
