In his recent segment, John Oliver joked about Pixy Stix training kids to do cocaine and it reminded me that I used to do just that. Although I never used the straw, I just leaned in, closed one nostril, and went for it. I was in 5th grade, it made my friends laugh.
Never did this myself, but I watched a guy in the army crush and snort Altoids once. Boredom can make you do dumb things.
