Sounds like your buddies website is taking info from the 70's. I mean "Columbian" ? My guess is that the amount of Columbian weed being brought into the U.S these days is slim to none. The majority of weed consumed in the U.S now is grown in the U.S. with Canada coming in second. I was reading an article a while back that said that even most "Mexican" sold in the U.S is actually grown in California. Although typically by the same Mexican's that were previously involved in bringing it over the border. It seems it's cheaper to grow here in Cali with less risk of being caught. LOL.
