It's well documented that bottles of sublingual nitroglycerin spray are allowed in carry-on and checked baggage, as an essential personal medication:
Nitroglycerin medication
- Carry on baggage: Yes
- Checked baggage: Yes
Nitroglycerin medication: Liquid prescription medications are exempted from the liquid restrictions and can be carried in carry-on baggage in volumes larger than 100 ml (3.4 oz.). These liquids must be declared to the Screening Officer separately. To facilitate screening, CATSA recommends that the medication be properly labelled (professionally printed label identifying the medication or a manufacturer’s name or pharmaceutical label).

But, do problems occur when going through airport security if some of the medication has accidentally (or perhaps intentionally as a "joke") contaminated one's luggage or clothing?
