Drug info - traveling / going through customs

[bodiesenmotion]

So SWIM is going on a cruise in a couple of hours and just realized right fricken now that he just did a couple of lines off of his laptop and there is probably some remnants on his back pack.

What SWIM wants to know is should he completely wash his back pack and laptop now, or just plain ole change backpacks and leave the laptop at home. How strict / thorough are they about checking these kinda things for debris and such???

Please dont reply if you have "well i think you should" thoughts. I need definite answers or previous experiences.

*Sorry to sound so mean, but id be kinda sad if i couldnt go on the forums anymore because they dont have internet in prison*
