Been done man. The pigeon was caught carrying 45 grams of cannabis into prison. http://www.cannabisculture.com/v2/node/25930
Don't be ridiculous, everyone knows marijuana won't kill you! Seriously, don't catch it, just shoot it over the border and let your partner pick it up.
All that effort to toss about $10,000 wholesale of brick weed across..lol..damn. Why not do that in some remote area with a van/truck on the otherside and toss over kilos of coke or something worth a lot more money?!
You know, if people simply went outside in large numbers in public places and they all smoked some weed, it would force the hand of government to change the laws in no time.
