                                A scientific study published in *PLOS ONE* confirmed that all tea leaves from the *Camellia sinensis* plant contain naturally occurring nicotine, though in incredibly small levels. We explore exactly how much nicotine is in tea leaves and why this trace amount poses no health risk to consumers.
