I've only had to ditch weed once before aswell.....

it was in france when we were driving to spain.....we bought some well nice squidgy (sp) sort of hash....near the north of france.

we drove down from the north to the south, near the boarder of spain and still had probly a 1/2 of this well nice weed.....

so we took another day out and tried to smoke all this weed before we crossed the france/spain boarder (thinking there would be police at the boarder).....

so we smoked and smoked as much as we could....and still had a BIG 1/8th left at the beginning of the next day.

We decided to continue our journey to spain and just left the weed on a picnic table in a carpark and continued our journey.......

only to find out there was no boarder.....no police no signs no nothing....one minute we were in France the next all the directions and names were in Spanish........we were pretty pissed off.

and there you go the first and last time i have ever had to ditch my weed.....it sucked.
