Here's what I've done - and this was going to Cuba, very difficult to find bud there.
1. Ground my bud in the coffee grinder - bout 1/2 oz
2. filled a number of McDonalds drinking straws with my bud - this took a while and I packed as much as I could into each straw.
3. Taped each straw shut at each end and taped entire straw
4. Cut strips of saran wrap (cellophane) 1 strip per straw
5. but baby powder (talcum) on each strip of saran wrap
6. Placed the straw in the middle and wrapped the saran wrap and baby powder anround each straw.
7. Tape tape tape
8. Cut a hole on the inside waistband of my jeans
9. Fed each straw through the hole in the waist band
I figured that would cover the smell and I had no problems at customs, just be cool.
