As a bonus, if we already have a heart condition and an abundant supply of prescription nitroglycerin tabs, we can perform the aforementioned prank to give all our friends heart attacks too! 😄
A tab of NTG is only 0.5mg, a drop of pure NTG (so around the size of the tab) would be in the ballpark of 125 mg, so the tablet contains very little NTG. Id wager a tiny pop if any.
This triggered a lost memory of watching bootleg MacGyver with some friends while getting blackout drunk celebrating Estonian reindependence after the soviet occupation collapsed. It was in German (None of us spoke German) and he was also doing something with some nitroglycerin on a truck.
