Cannabis has been used by humans for thousands of years and during this time many cannabis plants have been taken from their original environment, planted, grown, and cultivated in more controlled environments.
The constant crossing of strains to create new strains and increase potency has made it hard to find a pure landrace strain at your local dispensary or anywhere on the market.
Fortunately, despite the extreme amount of crossbreeding between strains, cannabis landraces can still be found growing around the world.
Wild Marijuana Or Ditch Weed In The US.
Industrial hemp was widely cultivated in the US’s Midwest during the 20th century. This was mostly to support the America’s war efforts in World War II.
Despite industrial hemp factories shutting down the plants previously cultivated for fiber, the hemp plants have naturally re-seeded and now grow wild in states like Oklahoma, Missouri, Nebraska, Indiana, and Minnesota.
There is still wild weed growing all throughout the United States especially in the mid-west.
The Drug Enforcement Administration defines ditch weed as “wild, scattered marijuana plants [with] no evidence of planting, fertilizing, or tending.”
The DEA has a Domestic Cannabis Eradication/Suppression Program which aims to eradicate cannabis in the U.S.
According to a report from 2003, 99% of the cannabis eliminated under the suppression program was ditch weed.
Eradicating wild weed is a particularly hard task. Indiana has a high concentration of feral weed. So bad that authorities in the area have given up on trying to get rid of it.
One police spokesman said “you can eradicate ditch weed as well as you can eradicate dandelion.”
Wild weed can be hard to get rid of because the seeds can lie dormant for 7 to 10 years before they eventually sprout.
