Teens who use e-cigarettes may be more likely to try marijuana in the future, especially if they start vaping at a younger age, a new study shows.

More than 1 in 4 teenagers who reported e-cigarette use eventually progressed to smoking pot, according to the survey of more than 10,000 teens.

That compared with just 8 percent of non-vapers, said lead researcher Hongying Dai, senior biostatistician with Children’s Mercy Hospital in Kansas City, Mo.

Further, teens who started vaping early had a greater risk of subsequent marijuana use.

Kids aged 12 to 14 who used e-cigarettes were 2.7 times more likely to try marijuana than their peers, compared with a 1.6 times greater risk for teens who tried vaping between 15 and 17.

“Our findings suggest that the widespread use of e-cigarettes among youth may have implications for uptake of other drugs of abuse beyond nicotine and tobacco products,” Dai said.
