Unless you come across that one special person who it just so happens will have a severe allergic reaction and end up dying (i.e., like the Bengay girl recently in the news).

Deaths from the topical salicylate poisoning appear to be extremely rare. Borakove said this was the first case she has ever encountered in 20 years with the medical examiner's office. None of the doctors contacted by reporters for this article could recall any others. Research into medical journals revealed a few reports of salicylate toxicity when absorbed through the skin, but no deaths.
