I was watching “Grease” the movie the other day and the scene where Marti is complaining that Vince Fontaine tried to put an aspirin in her Coke at the dance struck me as odd. What is the big deal? People take aspirin all the time for headaches, etc yet it never seems to do them any harm. Will taking an aspirin when you don’t have to make you ill?
It was an old urban legend that aspirin mixed in Coke would get you drunk. Grease is referring to that – it had been thoroughly debunked by the time the movie came out, but it was still current in the 50s.
Many painkillers do contain caffeine. This increases the effectiveness of the painkilling drug. The amount of caffeine in an aspirin would not be enough to make any difference, in my opinion.
Let’s see, apsrin reduces the protective coating in your stomach and the caffeine increases the production of acid in your stomach. Sounds like a prescription for heartburn to me. Or worse if you go to extreme.
