Can you tell when someone is vaping in the bathroom?

FLIGHT ATTENDANTS: Myth Busting: Vaping in the Bathroom CAN YOU TELL VAPING IN THE BATHROOM? USUALLY THE SMELL IS WHAT GIVES IT AWAY. WE CAN ALWAYS TELL WHEN SOMEONE IS VAPING IN THE BATHROOM BECAUSE THE FIRE ALARM WILL GO OFF. THE PILOTS GET LIKE A NOTIFICATION IN THE FLIGHT DECK AND THEY IMMEDIATELY CALL US. HEY, WE'RE GETTING A NOTIFICATION. THERE'S A FIRE IN THE BATHROOM. WHAT'S GOING ON? IF IT SMELLS SUPER FRUITY OR SUPER MINTY, IT'S PRETTY OBVIOUS SOMETHING HAPPENED IN THERE. SOMETIMES PEOPLE WILL BRING, LIKE, VAPES ON BOARD AND HIDE IT, LIKE UNDER THEIR SWEATSHIRT OR WHATEVER AND THINK THEY'RE LIKE, SNEAKY AND THEY'RE NOT. WE SEE YOU. FIRST YOU GET A WARNING, AND THEN IF THEY CONTINUE TO KEEP DOING IT, THEY WOULD GET IN SERIOUS TROUBLE. THEY CAN BE FINED FOR UP TO $10,000 BY THE FAA. SO WE DEFINITELY DO KNOW WHEN YOU'RE VAPING IN THE BATHROOM FOR SURE.
