I moved to Asia and suddenly found it nearly impossible to get full strength Aspirin. Kind of frustrating as it seems to be the somewhat less harmful NSAID. Some research later, I found that it possibly interacts with certain bacteria that cause stomach ulcers and that these bacteria are more likely to be in poorly stored food. So, street food basically. This is a risk factor that would be much lower back home in Europe. I wasn't able to get a definitive answer on this, but it's the best one I found so far as to why Aspirin is common in Europe and almost totally absent in Asia.
