In 2026, you can legally bring a vape pen or e-cigarette through the security checkpoints at Disneyland, as they are not "prohibited items" for possession. You do not need to "hide" them; they can simply stay in your bag or pocket as you walk through the metal detectors. However, there is a strict "Zero-Tolerance" ban on using them anywhere inside the theme parks. Disneyland, Disney California Adventure, and the Esplanade are 100% smoke-free and vape-free zones. If you are caught vaping in a "secluded" corner or in a ride queue, you will be warned by a Cast Member, and repeat offenders are frequently escorted out of the park without a refund. To use your vape, you must completely exit the security perimeter and go to the designated smoking areas located near the parking structures or outside the Downtown Disney District. For 2026 visitors, the "pro-tip" is to switch to nicotine pouches or gum for the day to avoid the 20-minute walk required to reach a legal vaping spot.
