Teens and young adults who use electronic cigarettes are significantly more likely to use cannabis as well, according to a new study by a Canadian researcher. Pediatrician Nicholas Chadi’s analysis of previous research, published in JAMA Pediatrics, found that the likelihood of marijuana use was three to four times higher among youth who vaped.

One of the key findings showed the risk for younger adolescents aged 12 to 17 was higher than for young adults aged 18 to 24 years. “It’s an important discovery for us,” said Chadi, who is now based at Montreal’s Ste-Justine Hospital but conducted the research during a previous posting in Boston.

FDA links vaping to 127 seizures — expert says e-cigarettes can ‘alter’ teens’ brains

By Abby Haglage, Yahoo Lifestyle, August 8, 2019

With Comments from Nicholas Chadi

[…] Long promoted as a “safer alternative” to smoking by the companies that make them, e-cigs are being outed in new reports of their damaging health effects — something that’s especially worrisome, considering that one in 10 eighth graders have now reportedly tried them.

The most recent report comes from the Food and Drug Administration, which has received “127 reports of seizure[s] or other neurological symptoms” from 2010 to 2019 that are believed to be linked to vaping. The news is part of an ongoing investigation the agency has been conducting since April, one that has reportedly tied a troubling number of the neurological effects to teen use. […]

“The way young people are using e-cigs now, with very high doses of nicotine, can definitely induce something like a seizure, especially for people who are predisposed,” Chadi tells Yahoo Lifestyle. Read more

Poor Mental Health Ups Risk for Teen E-Cigarette Use

By Elizabeth Hlavinka, MedPage Today, June 4, 2019

With Comments from Nicholas Chadi

Teens with mental health problems were more likely to take up cigarettes, both electronic and regular, according to a longitudinal study just published in Pediatrics.

[…] “We have to be careful when we think of e-cigarettes as substances because it falls in the bigger picture of substance use in general,” Chadi, who was not involved with the research, said. “This is a two-way highway, where people with mental health problems are more likely to start using these substances, but the reverse is also true — people who start using these substances also have increased chances of developing mental health symptoms.” Read more

Opening the Weedgates: Youth at risk

By Sheela Clary, The Berkshire Edge, April 2, 2019

With comments from Nicholas Chadi

Despite the official prohibitions on studying cannabis as well as the resulting lack of scientific evidence, it is by now understood well enough that the human brain continues to develop until the age of 25, and cannabis can alter that development, resulting in adverse life outcomes. […]

For clarification on why it makes sense to discourage youth from using marijuana, I contacted Dr. Nicholas Chadi, a pediatrician specializing in adolescent and addiction medicine and a pediatric addiction medicine fellow at Boston Children’s Hospital. […]

Dr. Chadi offered that one of the biggest hurdles he faces in treating teenagers who present with marijuana dependence problems is the widespread perception that marijuana is either harmless or beneficial. Read more

States Raising Smoking Age to Combat Teen Vaping

By Jennifer Clopton, WebMD, March 15, 2019

With comments from Nicholas Chadi

Nicholas Chadi, MD, has had a front-row seat to the high-speed growth of vaping among teens. Chadi, a pediatrician who specializes in adolescent and addiction medicine, says he didn’t have any kids coming to Boston Children’s Hospital for e-cigarette use 2 years ago. Now, they see someone in their clinic as often as once a week.

“For a lot of teens, it’s the main concern they or their parents have. It is becoming pretty center-stage,” he says.

Some of the teens “are completely addicted, and it’s taken over their lives,” Chadi says. “Teens who come to see us couldn’t even sit in class for an hour. They had to leave because they felt they were having withdrawal symptoms, and we’ve seen teens dropping out of sports teams because they are so focused on their e-cigarette use.” Read more

Medical marijuana: What’s all the buzz?

By Nicholas Chadi, Thriving Blog, March 14, 2019

Is medical marijuana safe for children and teens? Depending on who you ask, you may get very different answers.

On one side, pro-marijuana websites, marijuana companies and dispensaries are keen to promote the numerous (often unproven) benefits of using marijuana for medical reasons. On the other side, many public health agencies, community organizations and pediatric providers warn about the risks of marijuana use during childhood and adolescence, making it quite challenging to form an unbiased opinion.
