Vaping has led to a dramatic rise in nicotine and marijuana use among young people in recent years. Marijuana vaping among 12th graders, for instance, nearly doubled from 2018 to 2019, according to the National Institute on Drug Abuse (NIDA).
Vaping involves inhaling an aerosol, or vapor, that may contain addictive drugs, including nicotine or THC (a chemical in marijuana that can affect behavior, mood, and thoughts). Because of the capacity of vaping to damage the lungs, it's also a major concern as COVID-19 spreads. NIDA Director Nora Volkow, M.D., spoke about these concerning trends and how the institute is addressing them head on.
What kind of story is the latest data showing?
There has been a very abrupt increase in vaping THC. This was the second highest increase we've ever seen since the inception of the NIDA Monitoring the Future Survey in 1975. The first was the increase in vaping nicotine in 2018. These both have worried us enormously. More teenagers are embracing vaping as a culture for taking drugs that they may not have taken otherwise.
Why is vaping so concerning, especially with marijuana?
Particularly among teenagers, one of the main concerns that we have about the use of marijuana is that it can interfere with the developing brain. The data that has emerged indeed has shown that teenagers who smoke marijuana are at much greater risk of becoming addicted to it. And becoming addicted as teens increases the risk of becoming addicted to other drugs as you age.
How is NIDA research responding to these trends?
"Smoking chemicals can produce severe lung damage."
- Nora Volkow, M.D.
We're interested in treatments. And we're interested in how vaping is influenced by social networks. Right now, there are no published studies regarding the treatment of teenagers who have become addicted to vaping nicotine or vaping THC. So, we're encouraging researchers to do clinical trials to see what interventions may be most beneficial. That includes, for example, testing other approaches that have been useful, particularly in teenagers, in helping them stop smoking nicotine.
What should teens, parents, and others know about vaping and COVID-19?
We know that individuals who have conditions of the lung or the heart, like those who smoke or vape, are at greater vulnerability of contracting the disease. That's because smoking chemicals can produce severe lung damage. We want people to be cautious and mindful of the possibility of a negative interaction.
