NEVER DO THIS! This is a few years old. I had a bad headache and I thought it would be a good idea to take some BC powder, which is basically powdered aspirin and caffeine. I heard that the fastest way to get it in your blood stream was to snort it, so I grabbed a hundred dollar bill and went to town. It was like being punched in the face. Instant pain, as you can see. Side note, you see me grab my ear. My ear was shooting with pain that didn't go away till the next day, and I had the taste dripping down from my sinus for a week, even after I flushed them out with salt water. So, don't ever do this. If you have a headache, please just take an ibuprofen like everyone else.
