Connecticut smoking laws ban lighting up inside most public buildings, workplaces, restaurants, and bars, and they extend the prohibition to the outdoor area within 25 feet of any doorway, operable window, or air intake vent. The rules live mainly in Connecticut General Statutes Section 19a-342, and they cover cannabis and hemp along with tobacco. Vaping is regulated separately but with heavy overlap, so an e-cigarette is treated like a lit cigarette in nearly every place the indoor ban applies.
Where You Cannot Smoke in Connecticut
Section 19a-342 lists the settings where smoking is prohibited inside the building and within a 25-foot buffer around doors, operable windows, and air intakes. That buffer is wider than many people expect, and it is not limited to main entrances.
- Buildings owned, leased, or operated by the state or a political subdivision
- Hospitals, clinics, and psychiatric facilities
- Any part of a retail store that is open to the public
- All indoor areas of restaurants
- Any indoor area of a business holding a Connecticut liquor permit
- School buildings and school grounds
- Child care facilities, inside and on the grounds (family child care homes are covered during business hours when enrolled children are present)
- Hotel and motel guest rooms rented as accommodations
- Public and private college dormitories
- Correctional facilities and halfway houses
- Rail, busway, and bus platforms and shelters operated by the state or a political subdivision
- Passenger elevators
- Dog tracks and simulcasting facilities
The statute defines “smoke” to include the burning of a cigarette, cigar, pipe, or similar device containing tobacco, cannabis, or hemp.1Justia. Connecticut Code 19a-342 – Smoking Prohibited So the same rules that stop someone from lighting a cigarette in a restaurant also stop a joint from being smoked there.
Vaping and E-Cigarettes
Connecticut treats vaping under its own statute but applies it to the same kinds of locations. Electronic nicotine delivery systems and vapor products are banned in government buildings, health care institutions, retail stores, restaurants, bars, school buildings, child care facilities, elevators, college dormitories, and simulcasting facilities.2Justia. Connecticut Code 21a-415 – Electronic Nicotine Delivery System The definition sweeps in e-cigarettes, e-cigars, e-cigarillos, e-pipes, e-hookahs, related devices and cartridges, and the liquid used in them.
The workplace statute also names vaping directly. Section 31-40q prohibits smoking and the use of electronic nicotine and cannabis delivery systems and vapor products in any business facility under an employer’s control.3Justia. Connecticut Code 31-40q – Prohibition on Smoking and Use of Electronic Nicotine and Cannabis Delivery Systems and Vapor Products in the Workplace
Exemptions
The exemptions are narrow. Each one carries conditions.
- Public housing projects, as defined under Connecticut’s controlled substance statutes
- Classrooms where smoking is part of a medical or scientific demonstration
- Medical research sites where smoking is integral to the research
- The uncovered outdoor portion of a bar or restaurant patio, but if the outdoor area has food service seating, at least 75 percent of those seats must be nonsmoking with clear signage
- Tobacco bars that meet a strict definition
For an area to qualify as “outdoor,” it must have no roof or ceiling enclosure of any kind.1Justia. Connecticut Code 19a-342 – Smoking Prohibited
Tobacco Bars
To qualify as a tobacco bar, an establishment must hold a liquor permit and meet one of two revenue tests. The first: during calendar year 2002, it generated at least 10 percent of total annual gross income from on-site tobacco product sales and humidor rentals. The second, for establishments that opened between January 1, 2003, and December 31, 2022: at least 60 percent of annual gross sales come from on-site tobacco products, verified by an annual independent audit. “Tobacco products” here means cigars and pipe tobacco only. Cigarettes, chewing tobacco, and cannabis do not count.1Justia. Connecticut Code 19a-342 – Smoking Prohibited
There are more conditions on top of the revenue test. The applicant must be located in a town with at least 80,000 residents where no other liquor-permitted tobacco bar already operates. The premises must include a built-in humidor and a separate ventilation system that does not recirculate air, meeting ASHRAE 62-2001 standards. Cigarette smoking and cigarette sales are not allowed on site, and the operator must provide health coverage to employees.4Connecticut Department of Consumer Protection.

Rules at Work
Section 31-40q is a separate workplace statute. It requires every employer to prohibit smoking, vaping, and the use of electronic nicotine or cannabis delivery systems in any business facility under the employer’s control.3Justia. Connecticut Code 31-40q – Prohibition on Smoking and Use of Electronic Nicotine and Cannabis Delivery Systems and Vapor Products in the Workplace
The statute does not require a written smoking policy, employee-communication protocol, or specific workplace signage. The obligation is the prohibition itself. Employers can go further voluntarily, including banning smoking on the entire property, but that is a choice rather than a legal requirement.
The Labor Department handles complaints and typically works with employers on compliance first. For persistent violations, the Labor Commissioner can ask the Attorney General to seek a $300 civil penalty or a court order compelling compliance.
Signs
Whoever controls a room, elevator, area, or building where smoking is banned must post signs stating that smoking is prohibited by state law, in a conspicuous location. In most settings the letters must be at least four inches tall with principal strokes at least half an inch wide. Restaurants, bars, hotels, and health care institutions still must post, but they are exempt from that letter-size rule.5FindLaw. Connecticut Code 19a-342 – Smoking Prohibited, Exceptions, Signs Required, Penalties Signs do not have to appear in every single room as long as they are posted in conspicuous common areas. Outdoor seating areas at liquor-permitted establishments that allow smoking must clearly mark the nonsmoking portion with written signage.
Penalties
Smoking in a prohibited area, failing to post required signs, or removing posted signs is an infraction under Connecticut law.1Justia. Connecticut Code 19a-342 – Smoking Prohibited Infractions are resolved in court without a jury and generally end in a fine. Both the individual who smokes and the person who controls the premises can be cited.
Workplace violations follow a different track, with the $300 civil penalty and injunctive relief described above.
Buying Tobacco: Age 21
Federal law raised the minimum tobacco purchase age to 21 nationwide in December 2019, and Connecticut backs that up with its own criminal statute. Under Section 53-344, anyone who sells, gives, or delivers cigarettes or a tobacco product to a person under 21 faces escalating fines:
- First offense: up to $300
- Second offense within 24 months: up to $750
- Each additional offense within 24 months: up to $1,000
Underage buyers who lie about their age can be fined up to $50 for a first offense and $50 to $100 for later ones.6Justia. Connecticut Code 53-344 – Sale of Tobacco to Minors The statute does not penalize someone under 21 who handles tobacco as part of a job, such as a store clerk stocking shelves, or as part of an approved medical research study on tobacco prevention and cessation.
Enforcement and Filing a Complaint
Enforcement is split among agencies, and no single office handles every kind of violation.
Sales to minors fall to the Department of Mental Health and Addiction Services, through its Tobacco Prevention and Enforcement Program. TPEP investigators run unannounced compliance inspections: random checks tied to the federal Synar Amendment’s noncompliance-rate measurement, targeted inspections at businesses with prior violations or public complaints, large-city sweeps, and joint inspections with local police. Every tobacco merchant is supposed to receive at least one inspection within any 18-month period.7Connecticut Department of Mental Health and Addiction Services. TPEP – Enforcement and Compliance TPEP also runs announced “merchant education” visits with compliance materials.
Smoking violations at liquor-permitted establishments go to the Department of Consumer Protection, which responds to complaints and inspects permit premises. Workplace complaints go to the Labor Department. For most indoor smoking problems at a bar or restaurant, filing a complaint with the relevant agency is the practical route, since inspectors cannot be everywhere and a complaint triggers a targeted follow-up.
