No: Some people think because it has "caine" in it that it could show up as cocaine, but it is a completely different chemical with no overlap with any drugs of abuse. Test kits do not test for it, and confirmatory tests like gas chromatography/mass spectroscopy will determine exactly what it is if there is any question on the screening tests.

Yes: It along with Procainamide are therapy of choice. The typical agents i.E adenosine, verapamil etc are not good as the can block conduction through the av node and allow rapid conduction through the accessory path and lead to hemodynamic collapse.
