At a time when more than 30 states and the District of Columbia have legalized the use of marijuana for either medical or recreational use, the U.S. surgeon general says no amount of the drug is safe for teens, young adults and pregnant women.

"While the perceived harm of marijuana is decreasing, the scary truth is that the actual potential for harm is increasing," Surgeon General Jerome Adams said Thursday during a press conference to 

Surveys show that an increasing number of adolescents and pregnant women use the drug, which can be eaten, smoked or vaped. 

But the surgeon general told NPR in an interview that many people are not aware of just how potent the drug can be.

"This is not your mother's marijuana," he said. The THC concentration in marijuana plants has 

increased threefold between 1995 and 2014

, according to the report, and concentrated products can contain up to 75 percent THC. 

"The higher the THC delivery, the higher the risk," Adams said.

Young people who regularly use marijuana are "more likely to show a decline in IQ and school performance [and] are more apt to miss classes," Adams said. And frequent use of the drug can also impair a child's attention, memory and decision-making.

"Nearly 1 in 5 people who begin marijuana use during adolescence become addicted," Adams said. "That's scary to me as the dad of a 15-, a 13- and a 9-year-old."

Symptoms of marijuana dependency include "irritability, mood and sleep difficulties, decreased appetite, cravings, restlessness, and/or various forms of physical discomfort that peak within the first week after quitting and last up to 2 weeks,"

And marijuana becomes addictive "when the person cannot stop using the drug even though it interferes with many aspects of his or her life," according to NIDA.

Health and Human Services Secretary Alex Azar announced that President Trump is donating part of his salary this quarter — about $100,000 — to fund a digital media campaign to bring attention to the risks of marijuana use.

There's still a lot that's unknown about the risks of marijuana, and federal officials say they support more local and federal research. Just this week, the Drug Enforcement Administration said it would start to process pending applications for permission to 

The Trump administration is not the first to sound the alarm about the rising use of marijuana. At a time when surveys point to a significant increase in the number of pregnant women using the drug, the American College of Obstetricians and Gynecologists is

. "Marijuana and pregnancy don't mix," the group urges. 

 that points to the range of risks for women and their fetuses, including disruption of brain development, smaller birth weight, higher risk of premature birth, and behavioral problems in childhood.

Bottom line, the surgeon general wants to remind people that despite what's happening in states, federal law hasn't changed. And there is good reason for caution.
