Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Time to maximal concentration for scopolamine after intranasal administration (Tmax)	Plasma scopolamine concentrations will be measured using an liquid chromatography-mass spectrometry (LC- MS) assay. Tmax is measured in minutes to reach the maximum concentration.	Baseline, 180 minutes
Primary	Side effects of intranasal scopolamine, as measured through a questionnaire with a subjective rating scale	A questionnaire will be administered asking about the participant's side effect profile after taking intranasal scopolamine. The questionnaire will have a subjective rating scale of 0-10 on the potential scopolamine side effects expected	180 minutes
Secondary	Effectiveness in reducing motion sickness as measured by duration of chair ride.	The degree of motion sickness will be assessed by measuring the total number of minutes the subject rides in the chair before stopping	Baseline, end of chair ride (maximum of 20 minutes)
