The question: I’ve heard that e-cigarettes may contain far more nicotine than regular cigarettes. Does that mean vaping is more addictive than smoking?
The answer: It’s true that some vaping devices can deliver more nicotine than cigarettes. But there are many different types of electronic cigarettes, and how they are used can affect the amount of nicotine that ends up in the bloodstream, and eventually the brain, says Dr. Robert Schwartz, a professor in the Dalla Lana School of Public Health at the University of Toronto.
The battery-powered e-cigarettes heat up a liquid containing nicotine to produce an aerosol, or vapour, which can be inhaled. (Flavourings and other chemicals may also be added to the fluid mixture.)

A lot depends on the nicotine concentration in the fluid and the power, or heat, generated by the e-cigarette. Other variables include how hard, how long and how often a person inhales. “Unless you know how to puff on the thing properly, and for long enough to heat the liquid sufficiently, you are not going to get huge amounts of nicotine,” says Schwartz.
So, it isn’t clear-cut whether cigarettes or e-cigarettes deliver more nicotine. But one thing is clear:
“What we do know is that both smoking and vaping can be addictive,” says Dr. Peter Selby, chief of medicine and psychiatry at the Centre for Addiction and Mental Health in Toronto
In fact, any amount of inhaled, chewed or snorted nicotine can be problematic – meaning that a person is likely to progress to daily use following a period of experimentation. “Nicotine is one of the most addictive substances we are aware of. It’s as addictive as heroin,” says Schwartz.
Originally, many public health experts looked upon vaping as potentially less harmful than smoking cigarettes, which produce about 7,000 toxic chemicals – including carcinogens – by burning tobacco. Some hope the devices might serve as quitting aids – or, at the very least, help reduce the number of harmful substances that smokers inhale.
But the recent surge in vaping among teens has set off alarm bells in the public-health community. And those concerns are intensified by reports of lung injuries among some vapers.
“My biggest concern is that we have already addicted a whole new generation of people to nicotine,” says Schwartz.

Teenagers – whose brains are still developing – are especially vulnerable to the addictive powers of nicotine, according to a growing body of research.
Nicotine attaches to receptors in the brain, thereby triggering the release of dopamine – a chemical messenger involved in pleasure and a wide range of other neurological functions. It basically produces a feel-good high.
When teens smoke or vape, it is believed that their brains create more receptors to handle the influx of nicotine. As the number of receptors increases, they need higher levels of nicotine to get the same buzz.
Some researchers have dubbed this effect the “nico-teen” brain. They also speculate that these neurological changes may have long-term consequences for mood and mental focus.
In the debate over vaping, much of the recent attention has been about the spate of serious lung injuries. Many of these cases appear to be linked to the vaping of cannabis oils such as tetrahydrocannabinol or THC. The latest evidence suggests that vitamin E acetate, a filler sometimes added to black-market THC, might be causing the injuries.
But even without THC, routine vaping – and the other chemicals in vaping liquids – may lead to long-term health problems.

“Kids who vape have almost twice the rate of coughing and wheezing as kids who don’t vape,” says Schwartz. Are these symptoms the early warning signs of chronic respiratory conditions such as asthma? Or, might vaping contribute to the development of cardiovascular disease? “We don’t yet know for sure,” says Schwartz. He adds that it will likely take some time to establish a clear picture of the risks.
Selby is also concerned that young people who have never used tobacco are now being drawn to vaping. He says better government regulations are needed to safeguard adolescents. However, he thinks vaping should not be vilified to the point where the devices are actually banned.
“Some individuals are going to take up tobacco smoking anyway, and they will be better off if they have the option to vape,” says Selby. “It’s all about relative risks between combustible cigarettes and vaping devices that deliver fewer dangerous chemicals.”
Indeed, despite the various problems linked to e-cigarettes, “there is very broad consensus in the scientific community that smoking is the most harmful way to use nicotine and it’s known to cause premature death in at least half of users,” says Schwartz.
According to Selby, “it would be completely ridiculous to ban the sale of vaping devices, while giving free reign to the most dangerous form of nicotine delivery – cigarettes.”
Shopping season for Medicare coverage is about to begin. With it comes the annual onslaught of TV ads and choices to consider.
People eligible for the federal government’s Medicare program will have from Oct. 15 to Dec. 7 to sign up for 2025 Medicare Advantage plans, which are privately run versions of the program. They also can add a prescription drug plan to traditional Medicare coverage.
Many people on Medicare Advantage plans will probably have to find new coverage as major insurers cut costs and pull back from markets. Industry experts also predict some price increases for Medicare prescription drug plans.
Shoppers often have dozens of options during this sign-up period. Here are some things to consider.
Don’t put off shopping for Medicare coverage
Start thinking about next year’s coverage before the annual enrollment window begins. Insurers will usually preview their offerings or let customers know about any big changes. That makes anything arriving in the mail from your insurer important to read.
Insurance agents say many people wait until after Thanksgiving to decide coverage plans for the new year. That could be a mistake this year: The holiday falls on Nov. 28, leaving slightly more than a week to decide before the enrollment window closes.
Look beyond the premium
Many Medicare Advantage plans promote a $0 premium. That may sound attractive, but price is only one variable to consider.
Shoppers should look at whether their doctors are in the plan’s coverage network and how prescriptions would be covered. They also should know the maximum amount under the plan that they’d have to pay if a serious health issue emerges.
Plans offer many supplemental benefits, including help paying food or utility bills. Don’t let those distract from understanding the core coverage, said Danielle Roberts, co-founder of the Fort Worth, Texas, insurance agency Boomer Benefits.
“Remember that we buy health insurance for the big things, not the frills,” she said.
How to get help shopping for plans
The federal government operates a plan finder that lets people compare options. The State Health Insurance Assistance Program can be another resource. Insurance brokers or agents also guide customers through searches.
Sometimes a plan’s coverage doesn’t work as expected. If that happens, there’s another enrollment window in the first three-months of each year where some shoppers may be able to make a change.

WASHINGTON (AP) — Americans can once again order COVID-19 tests, without being charged, sent straight to their homes.
The U.S. government reopened the program on Thursday, allowing any household to order up to four at-home COVID nasal swab kits through the website, covidtests.gov. The tests will begin shipping, via the United States Postal Service, as soon as next week.
The website has been reopened on the heels of a summer COVID-19 virus wave and heading into the fall and winter respiratory virus season, with health officials urging Americans to get an updated COVID-19 booster and their yearly flu shot.
“Before you visit with your family and friends this holiday season, take a quick test and help keep them safe from COVID-19,” U.S. Health and Human Services Assistant Secretary for Preparedness and Response Dawn O’Connell said in a statement.
U.S. regulators approved an updated COVID-19 vaccine that is designed to combat the recent virus strains and, they hope, forthcoming winter ones, too. Vaccine uptake is waning, however. Most Americans have some immunity from prior infections or vaccinations, but under a quarter of U.S. adults took last fall’s COVID-19 shot.
Using the swab, people can detect current virus strains ahead of the fall and winter respiratory virus season and the holidays. Over-the-counter COVID-19 at-home tests typically cost around $11, as of last year. Insurers are no longer required to cover the cost of the tests.
Before using any existing at-home COVID-19 tests, you should check the expiration date. Many of the tests have been given an extended expiration from the date listed on the box. You can check on the Food and Drug Administration’s website to see if that’s the case for any of your remaining tests at home.
Since COVID-19 first began its spread in 2020, U.S. taxpayers have poured billions of dollars into developing and purchasing COVID-19 tests as well as vaccines. The Biden administration has given out 1.8 billion COVID-19 tests, including half distributed to households by mail. It’s unclear how many tests the government still has on hand.
