LAX to allow pot in carry-on bags. TSA offers reminder that it's still illegal at the federal level.

Travelers flying out of Los Angeles International Airport are now permitted to pack pot in their carry-on bags, the airport announced on its website.

Airport police said it would allow passengers to stash up to 28.5 grams of marijuana and 8 grams of concentrated marijuana as part of their travel essentials, in accordance with California's Proposition 64.

"In accordance with Proposition 64, the Los Angeles Airport Police Department will allow passengers to travel through LAX with up to 28.5 grams of marijuana and 8 grams of concentrated marijuana," the statement said. The proposition, which went into effect on Jan. 1, allows adults 21 and older to possess marijuana for personal consumption.

However, marijuana is still illegal at the federal level, and air travel is governed by federal authorities.

What did the TSA say?

Transportation Security Administration spokeswoman Lorie Dankers told Fox News in a written statement that its agents are focused on passenger safety.

"TSA's focus is on terrorism and security threats to the aircraft and its passengers," Dankers said in an email.

If an agent finds someone's weed, they will alert police and turn it over to them to handle.

"Whether or not the passenger is allowed to travel with marijuana is up to law enforcement's discretion," she added.

As long as the traveler has no more than the legal limit, police will let them go, "because there is no crime," LAX airport Officer Alicia Hernandez told the news outlet.

What else?

Still, police caution people to think twice before embarking on a cannabis-fueled vacation.

Still the best advice to travelers, Douglas Kidd, executive director of the National Association of Airline Passengers, said, is to leave your stash at home. You can always buy more when you get there.

"The first thing the TSA is going to do is if they find something that is illegal for federal purposes is they're going to refer it to local law enforcement," Kidd said. "Now local law enforcement may say, 'We're not going to do anything.' But still, the delay could cause you to miss your flight."

Is this allowed at other airports?

There is no policy on marijuana at San Diego International airport, Jonathan Heller said, according to the report.

Colorado was among the first states to legalize recreational marijuana, but it still doesn't allow pot in Denver International Airport because possession is illegal by federal laws, according to airport spokeswoman Emily Williams.

The penalty has been minimal for those who have been caught with pot at the Denver airport, Williams told Fox News.

"If it's a small amount the TSA and the Denver Police Department will ask that person to dispose of it and if that person is willing to do that they move through," Williams said.

What else?

Passengers should consider the laws at their destination before taking their pot along on their travels.
