A friend of mine came into our uni house after we hadnt seen him a for a few days and says "I just come back from Poland and I came back through Amsterdam" and he pulled out £100 worth of weed and hash.

We asked him how he got it on the plane he just said that he cheeked it. Which is clenching it between both butt cheeks. Must have been hard to walk though.

This is what i always thought, put your bud in a bag and submerge it in something which has a strong odor e.g. Tub of marmite/coffee tin then dogs cant smell it. Not tried this though.
