It is well-known that smoking poses several health hazards. According to research, the younger a person starts smoking, the harder it is to quit the habit. Also, teens who smoke are at an increased risk of falling for alcohol and drug abuse (1).

Moreover, statistics show that teenagers who do not start using tobacco by age 18 most likely never start. Read this post to learn more about the health risks of cigarettes and other smokable tobacco products and tips to prevent smoking in teenagers.

Incidence And Prevalence Of Smoking In Teens

According to the Centers for Disease Control and Prevention (CDC), almost nine out of ten adults who smoke cigarettes daily have tried smoking first before the age of 18. Moreover, about 200 young people start smoking in the US each day (2).

According to the American Lung Association, almost 2500 children under 18 years of age try their first cigarette, and more than 400 of them end up becoming daily smokers. Sadly, half of them ultimately die due to the addiction (3).

From the data collected in 2020, the CDC states that 4.6 percent of high school students (3.9% girls and 5.4% boys) and 1.5 percent of middle school students (2.0% girls and 1.3% boys) use cigarettes (2).

  • They might think that it is cool to smoke.
  • They might slip into the marketing gimmicks made by the tobacco industry to lure teens into the habit.
  • In places where low tobacco taxes have kept the price down, it is easier for them to afford cigarettes.
  • Teenagers get thrilled about trying new things but do not have enough maturity to think of repercussions.
  • Nicotine in cigarettes is a feel-good drug that does not cause intoxication.
  • Genetic factors may make it more difficult for teens to quit smoking.
  • Maternal smoking during pregnancy may increase the probability of smoking in the child.
  • Smoking has a strong association with depression, anxiety, and stress.
  • It is more common in teens from low socioeconomic and those from uneducated backgrounds.

Signs A Teen Is Smoking

The following are the signs that may indicate your teenager is smoking (5) (6).

1. Bad breath

Teens who smoke have a typical smell of smoke emanating from their clothes, breath, hands and can be easily identified. The intensity of smell may vary based on the cigarette they use.

2. Stains

The nails and fingers of smokers may get a yellow stain due to exposure to smoke and tar from the cigarette. The lips may also have a bluish or black tint. The teeth may also wear a yellowish discoloration on the outside and brownish-black on the inside.

3. Open windows

Children may frequently leave their windows open, even when it is cold outside, to ventilate the room and prevent it from smelling like a smoke room.

4. Making excuses to go out

If the teen suddenly begins to leave the house more frequently than previously for short breaks, they might be smoking.

5. Chronic cough

Hoarseness of voice, throat irritation, and chronic cough may arise from regular smoking. If no other illness may cause these symptoms, smoking may be a reason.

6. Extreme mood changes

If your teenager acts unreasonably angry, irritated, or agitated, and you cannot point to an underlying cause, it may indicate a habit of smoking. The teen may be calmer after stepping out of the house and coming back. The addictive qualities of nicotine may keep your teen always on edge.

Apart from cigarettes, people may use cigars, bidis, kreteks, pipes, or hookah, etc., to smoke tobacco (10).

1. Cigar
  • A cigar is a roll of tobacco wrapped in a leaf or other material that contains tobacco.
  • Large cigars, cigarillos, and little cigars are the different cigars.
  • Cigars may lead to cancers, gum disease, tooth loss, coronary heart diseases, and lung diseases (11).

Frequently Asked Questions

How does nicotine affect my teen’s brain?

Exposure to nicotine through tobacco smoke during adolescent years may be harmful. It can disrupt the normal course of brain maturation, resulting in long-term negative outcomes regarding mental health, cognitive function, and personality (18).

How do I discipline a teen who smokes?

Punishment is not the best option when you discover that your teen is smoking or using drugs. Rather than arguing, take time to calm down and then have an open and honest conversation about it. Encourage them to open up to you, explain the consequences of smoking, and assure them that this conversation will be private. Also, setting consequences for smoking from early childhood will help prevent your teen from smoking (19).

Can I test my teen for nicotine?

Yes. Cotinine urine, blood, and saliva tests can detect the cotinine levels in the body, which is a chemical produced by the body when exposed to nicotine. However, nicotine gums and patches and breathing in secondhand smoke can also result in positive test results. After 7–10 days of not smoking or exposure to nicotine, the cotinine levels begin to return to normal (10 ng/mL) (20).

Is vaping or smoking worse for teens?

Many teenagers think vaping is safer than smoking. However, while vaping is less harmful than smoking, it is still unsafe and may cause heart and lung problems (21).

Can my teen recover from smoking?

Yes. Depending on the duration of smoking, the negative health effects of smoking can be reversed within 10–15 years of quitting. Within 20 minutes of quitting, the heart rate and blood pressure may return to normal, and within a year or two, the lungs begin to regain normal function, and the chances of a heart attack decrease. Finally, within 10–15 years of quitting, the incidence rate of lung cancer and coronary heart disease reaches that of a nonsmoker (22).

It is not easy to quit smoking – for adults or teens. There might be some challenges, but be positive and encouraging about it. Help them connect with local or online support groups where other people of their age are also trying to quit smoking. This way, they will get the necessary motivation to break the habit and lead a healthy life.
