No, vaping while driving isn’t explicitly illegal in Maryland for nicotine or tobacco products alone, but it can lead to distracted driving charges if it impairs safe operation. State law bans cannabis consumption in vehicles entirely, with separate rules for minors and impairment.
No Direct Ban on Nicotine Vaping
Maryland lacks a specific statute prohibiting vaping nicotine e-liquids or smoking cigarettes solo in private vehicles. This holds for adults driving alone or with other adults, as private cars aren’t classified as public spaces under smoking bans.
Officers enforce via broader laws: Transportation Code § 21-1124.2 covers handheld distractions, while general careless driving applies if vapor clouds, device handling, or ash cause swerving.
Cannabis Vaping Prohibition
Drivers and passengers cannot smoke or vape cannabis in a vehicle’s passenger area on highways, including parked lots—per § 21-903(c). This civil offense carries fines up to $25 for passengers, escalating with DUI if impaired.
Impairment from any substance triggers DUI charges under strict post-legalization rules.
Minors in the Vehicle
No statewide ban exists yet for nicotine vaping around kids, though HB 1392 (2025) failed. A proposed HB 544 (2026) seeks misdemeanor penalties (up to 1 year jail/$1,000 fine) for cannabis use near minors, aligning with tobacco rules. Health risks drive advocacy, but it’s not law as of May 2026.
Distracted and Reckless Driving Risks
Vaping qualifies as a distraction if it diverts attention—primary enforcement allows stops without other violations. “Jake’s Law” ups penalties for injury/death crashes.
Reckless driving (§ 21-901.1) or negligent operation follow accidents tied to device use.

Enforcement in Practice
Police observe erratic driving before citing; visible clouds or fumbling provide pretext. No sobriety tests target nicotine, but cannabis odor prompts checks.
Best Practices
Pull over to vape, use hands-free setups, or wait till parked off-highway. For cannabis, store sealed in trunk. New 2025 laws like HB 744 expand reckless driving thresholds.
