Canada ? A peanut butter kiss was not the kiss of a death for a teenager with a peanut allergy.

A Quebec coroner said Monday that the girl died from a lack of oxygen to her brain – not from kissing her boyfriend following his peanut-butter snack.

Coroner Michel Miron declined to disclose the exact cause of death because he has yet to submit his final report to the provincial coroner’s office. But he told The Associated Press he hoped to end the “phobia” the case has caused.

Christina Desforges, 15, died in a Quebec hospital in November. Officials had said the doctors were unable to treat her allergic reaction to a peanut-laced kiss from her boyfriend the previous weekend.

Miron said the girl and her boyfriend had kissed, but many hours after he ate peanut butter. By then, he had eaten popcorn and drunk beer, generating saliva that would have cleansed his mouth before the kiss.
