"Flying with weed" was the article I've recently found out on the site NCSM.nl and the info was very useful and important to know for me! It's upset the marijuana is not legal in all states in the US. To know how to behave and how and where to buy is very important if you don't want to get in a "prison" You know, in most of the countries around the world, whatever the circumstances might be, it is illegal to travel with Marijuana with any airline. However, for flights that making rounds within Canada, it has been announced by the transport authority has announced that passengers will now be able to fly with about 30 grams of Marijuana, 150 grams of medical cannabis, or 100 ml or cannabis oil in checked baggage.
