LAX Airport has officially updated their marijuana policy. According to the LAX website you can now legally travel through the airport with weed.
This has legally been a policy since January 1, 2018 when California passed Prop 64 which allowed the legal personal possession of cannabis with adults 21 and over. You are allowed to travel with at least one ounce of mary jane or eight grams of hash through the airport, officially.
This updated policy means that law enforcement officials and TSA will not arrest you if you have weed in your luggage within the legal limit. What a time to be alive!
NOTE: you are still at risk of arrest if you travel to a state where marijuana possession is prohibited.
