Liquid chromatography-mass spectrometry was used to identify and quantify the predominant capsaicinoid analogues in extracts of fresh peppers, in oleoresin capsicum, and pepper sprays. The concentration of capsaicinoids in fresh peppers was variable. Variability was dependent upon the relative pungency of the pepper type and geographical origin of the pepper. ⋯ Variability was observed among products obtained from different manufacturers as well as from different product lots from the same manufacturer. These data indicate that commercial pepper products are not standardized for capsaicinoid content even though they are classified by SHU. Variability in the capsaicinoid concentrations in oleoresin capsicum-based self-defense weapons could alter potency and ultimately jeopardize the safety and health of users and assailants.

As a victim of his parents' suicide, a three-year-old boy was found dead on the lap of the passenger in the left front seat of a car that dove from the wharf and crashed into the sea. He died from the transection of trachea due to shoulder belt in the absence of the signs of drowning. The seat belt paradoxically injured the child on the passenger's lap in the traffic accident. The popular custom of Japanese parents of holding their children on their laps in cars is dangerous, while another custom of killing their children upon suicide of parents or couples should be socially and legally controlled.
