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.
Snow Globes. TSA will allow snow globes that contain less than 3.4 fluid ounces in carry on luggage (approximate size of a tennis ball). This is determined and allowed only if the entire snow globe is small enough to fit in one clear, quart sized plastic bag, in accordance with the rules for other liquid items. Snow globes are permitted in checked baggage.
