Step 1: Vacuum seal your shit - that gets rid of the smell. (Be sure to wear latex gloves when handling your stash, and once the bag is sealed, CLEAN IT with anti-bacterial detergent. A lot of ppl forget to clean the bag and thats how they get busted.

Step 2: Wherever you put your stash, be sure that it will be unrecognisable under x-ray. A nice way to do it is to open up and electronic device, take out the workings, and put the bag inside. Under x-ray its not too noticeable. Another way to do it is to put it in an empty shampoo bottle, or something else that is supposed to contain a liquid.

In any case, transporting through an airport is dodgy, no matter how many precautions you're taking. Rather mail it, or courier it, to your destination. They are less strict than airport security and if it does get intercepted then they can't trace you (If you leave a return address or your real name then you deserve to get caught).

Either way you should thoroughly research airport security on the net, and figure out the best steps to take.

Again if it were me I wouldn't be caught near that gear if its going through an airport. I normally post it as overnight to my destination under a fake name and pick it up (I have 'special' ID just for this)
