Vaping has become more popular over the years, especially among teens and young adults. But with more attention on the health risks and legal concerns, questions are being raised about when and where vaping is allowed—especially when you’re behind the wheel.
So, is it illegal to vape and drive in Washington State? Here’s what the law says.
Can You Vape While Driving in Washington?
As of 2025, there is no specific law in Washington that bans vaping while driving for adults. If you’re over 21, you can legally vape inside your car—as long as it’s not affecting your driving or endangering others on the road.
However, if you are distracted by vaping, like adjusting your vape device or blowing thick clouds that block your view, you could still be cited for distracted or negligent driving under Washington’s traffic safety laws.
Also, vaping while driving with minors in the car is highly discouraged, and certain local jurisdictions may have their own rules or penalties related to child exposure to vapor products in vehicles.
Legal Age to Vape in Washington: 21 and Up
As of January 1, 2020, Washington State raised the legal age to 21 for buying and using vapor products. This aligns with the national “Tobacco 21” law.
It is illegal for anyone under 21 to buy, possess, or use vape devices. Stores are required to check ID and make sure products are not within reach of minors. Vaping among youth is a major concern in Washington, and enforcement efforts have increased to prevent underage access.
Where Is Vaping Banned in Washington?
Even though you can legally vape in your car (if you’re an adult), Washington has strict rules about where vaping is not allowed, especially in places where children are present or in public spaces.
School Grounds
Vaping is banned in all schools, school buses, and at school events—even outside on school property.
Public Places and Buildings
Many cities and counties in Washington treat vaping the same as smoking. That means you cannot vape inside most public buildings, restaurants, bars, or workplaces. Local ordinances may extend these bans to parks, beaches, or public transit areas.
Retail Stores and Product Access
Under Washington law (RCW 70.345), retailers must:
Have a license to sell vapor products
Keep vape products out of reach of minors
Avoid using flavors or packaging that appeal to children
Public Health and Safety Concerns
Washington’s Department of Health strongly warns against using vapor products due to serious health risks. Research has shown that flavoring chemicals used in vape liquids can be toxic when inhaled, even if they are safe to eat.
Ingredients like propylene glycol and glycerin, common in vape liquids, can irritate the lungs when heated. Nicotine is highly addictive and increases the risk of heart and lung disease. That’s why health officials urge people—especially teens—to avoid vaping completely.
The Rise of JUUL and Youth Vaping
Devices like JUUL have made it easier for young people to hide vaping. These small, USB-like vape devices are popular with teens and carry nicotine levels equal to a pack of cigarettes per pod. From 2016 to 2018, vape use among 10th graders in Washington jumped from 13% to 21%, and among 12th graders, it rose to nearly 30%.
Vaping while driving in Washington is not directly illegal—but it becomes a problem if it distracts you or puts others at risk. If you’re 21 or older, you can legally vape in your car, but it’s important to stay alert and avoid using your device in ways that interfere with driving.
At the same time, vaping laws in Washington are strict when it comes to where you can vape, who can buy products, and how they are sold. Whether you’re a driver, a parent, or a business owner, knowing these rules can help you stay safe and legal.
