THC Limit IntroA prominent farmers association is calling for the US Department of Agriculture (USDA) to officially increase the maximum allowance of THC for industrial hemp crops. The American Farm Bureau Federation (AFBF) is one of the largest farm organizations in the United States, and they believe that the THC limit for hemp should be raised to 1%. Farmers who jumped on the hemp bandwagon have been finding it difficult to keep their new crops under the federal limit of 0.3% THC, and it’s costing them a lot.
THC Legal Limit
In Arizona, over 40% of the hemp crops tested since December have exceeded the legal limit and will have to be destroyed, at a loss of about $13.4 million.
This means that the state’s farmers will lose four out of every ten hemp crops, with no recourse or compensation with the sale of their hemp derived cbd oils.
The USDA has estimated that in 2020, at least one in five lots of hemp will likely exceed the THC limit and have to be destroyed.
This policy seems incredibly wasteful and unfair, as many farmers are now losing the money they invested into their new hemp crops. There are numerous uncontrollable factors that determine how much THC is produced in a hemp plant, including soil and climate.
Warmer temperatures are associated with a higher THC content in cannabis, which might help to explain why Arizona farmers had so many issues keeping the keeping the percentage down.
THC, or tetrahydrocannabinol, is the only compound in cannabis that has psychotropic characteristics, and it is the sole determinant that legally distinguishes hemp from commercial marijuana. This is problematic for several reasons, primarily because the botanical definition of hemp is much more extensive than simply its quantity of THC. In 2015, a group of Canadian scientists conducted a study which reported that “marijuana and hemp are significantly differentiated at a genome-wide level, demonstrating that the distinction between these populations is not limited to genes underlying THC production.” This begs the question: why was the level ever set at 0.3% in the first place?
THC LevelThe 0.3% THC level limit was originally established by researchers as an easy way to differentiate between hemp and marijuana for the purpose of their study, but it was never intended as an official number or meant to be used as the method for legally defining hemp. However, politicians eventually latched onto that figure without really understanding or asking whether it was necessary for it to be that low. The general threshold for THC to cause intoxicating effects is around 1%, so it would seem that would be a logical number to start with. Many countries have already implemented policies which establish the maximum THC limit as 1%, including Uruguay, Switzerland, Australia, Thailand, and most recently, Ecuador.
Farmers have until January 31st to submit their comments to the USDA regarding the new hemp growing policies. In addition to raising the THC limit to 1%, farmers are also asking that industrial hemp crops which are intended for clothing or non-ingestion should be exempt from THC testing altogether. At the very least, they would like to be able to use the high testing crops for use as bio-fuel or compost, instead of just having them destroyed.
In order for the United States to be competitive in the global hemp market, the regulations for cultivation should be fair and based in science, not arbitrary rules that are mandated by politicians who simply don’t know any better. Hopefully, the USDA will be receptive to the opinions that are being submitted, and work to fix the issues that are preventing hemp farmers from being able to make a profit.
