Drug Test Detection of Cocaine for Nasal Intubation

The objective of this study is to determine whether it is possible to detect traces above national cut-offs of either cocaine's main metabolite benzoylecgonine in saliva or cocaine in blood 24 hours after administering 2 ml of 40 mg/ml cocaine-saline to the nasal mucosa. The investigators hypothesize that the level of cocaine's main metabolite bezoylecgonine in saliva after cocaine administered for anesthetic purposes will be below detection limits after 24 hours.
