Yes, smoking Smarties can be dangerous. When the trend first reached virality in 2009, pediatrician and mom of three Dr. Lisa Thornton sat down with Early Show co-anchor Maggie Rodriguez to discuss the health risks associated with it.

"If you look at the behaviors this is promoting, it's promoting this pre-smoking behavior. There's this whole ritual around how these kids do this, and it looks like smoking. So I'm concerned that the next step is smoking," she said.

She further explained that because kids inhale it like a cigarette, it puts sugar in their lungs. "You'll cough because that's what your lungs do as they try to clear out anything foreign that gets in there," she continued.

While she noted that inhaling Smarties won't harm a kid physically, breathing in all of that sugar is definitely not recommended. Furthermore, Thornton suggested that parents begin talking to their kids (as early as 6 years old) about why smoking in all forms is dangerous.

"You can start talking about it. And when you're somewhere and kids smell the smoke, they'll notice that it's irritating and they don't like it. And you can discuss that that's something that we don't do, that's very dangerous. My kids are all very tuned into this. They know that this is a big health risk. So, I hope that kids don't start doing this and then making it a cigarette instead," she said.
