Snorting half a shaker of pepper may cause discomfort and irritation in the nasal passages, but it is unlikely to cause any serious harm or injury. On the other hand, snorting a live bee can be extremely dangerous and potentially life-threatening, as the bee can sting and cause allergic reactions or other complications. Therefore, snorting half a shaker of pepper is the safer and less risky option compared to snorting a live bee.
