Recreational Marijuana States. Four states, including Alaska, Oregon, Colorado, and Washington, as well as Washington D.C. have passed ballots legalizing recreational marijuana. The amount you can possess at one time, however, varies between the states.
As of January 31, 2014, passengers traveling internationally into the U.S. and connecting to another flight are allowed to have in their carry-on baggage liquids in excess of 3.4 ounces (100 mL) that were purchased as duty-free merchandise.
TSA limits the amount of liquids that can be brought onto the plane in your carry-on with its 3-1-1 rule. This includes cosmetics in liquid form such as eyeliner, nail polish, foundation and moisturizers. It also includes perfume. The rule states that any liquids must be in a resealable container that is 3.4 ounces or less and that all containers must fit in one clear, plastic, resealable 1-quart-sized bag. You will need to take this bag out of your carry-on luggage when passing through airport security.
