The Drug Enforcement Administration has kicked its lobbying against legalizing industrial hemp into high gear, hoping to block an amendment in the House that would decriminalize the crop for research purposes. 
 
 The amendment to the farm bill, proposed by Rep. Jared Polis (D-Colo.), is far more modest than a Senate effort by Minority Leader Mitch McConnell (R-Ky.) to fully legalize the crop for industrial purposes. That measure never found its way into the Senate version of the bill. The House may vote on Polis' amendment as soon as Tuesday evening. 
 
 The Huffington Post has obtained a copy of talking points the DEA is circulating among members of Congress to press them to oppose the amendment -- raising the seemingly incongruous specter of the government using its resources to lobby itself. 
 
 The talking points, paradoxically, represent a step forward in the debate. In the Senate, hemp advocates were left only to counter vague "law enforcement concerns" that senators told HuffPost were a factor in their willingness to support reform. With the DEA laying out those specific concerns, hemp backers will attempt to rebut them point by point. 
 
 Broadly, the DEA's case focuses on the supposed inability to easily distinguish between hemp and its cousin, marijuana. The similarity, the DEA argues, would allow pot growers to shield their plants behind rows of hemp plants. But the DEA appears not to have gotten the talk about the birds and the bees. A pot grower who allowed hemp plants near a prized marijuana crop would risk cross-pollination, which would result in a dramatically inferior product. In fact, California pot growers have been avid opponents of legalized hemp for just that reason. 
 
 Hemp is legal to grow in many industrialized countries, including Canada, and is legal to import into the U.S. States such as Polis' Colorado and McConnell's Kentucky have legalized hemp growing, but await federal action. 
 
 Talking points from hemp advocates can be found here. The Senate bill was cosponsored by McConnell and Sens. Rand Paul (R-Ky.), Jeff Merkley (D-Ore.) and Ron Wyden (R-Ore.). 
 
 Below are the talking points circulated by the DEA on Wednesday: 
 
 The amendment (Polis) relates to marijuana (hemp) cultivation for industrial purposes. Marijuana (hemp) cultivation is already permitted under current law, provided the grower has obtained a DEA registration. This bill would eliminate the DEA registration requirement and completely decontrol marijuana grown for industrial purposes by defining "hemp" as marijuana that contains 0.3 percent or less THC, then declaring this "hemp" to be a noncontrolled substance. This would clearly impede law enforcement in several respects. First, it is impossible to distinguish a marijuana plant containing 0.3% or less of THC from a marijuana plant containing higher THC levels without scientific analysis. The bill would thereby make it essentially impossible for law enforcement to enter a grow site to determine the THC content of the "hemp" plants since there would be no way to establish probable cause to obtain a search warrant without first entering the premises to collect samples. As a result, the bill would provide easy cover to hide more potent marijuana plants. Second, even if all the marijuana plants contained 0.3 percent or less THC, they would still provide an enormous quantity of psychoactive material because it is very easy and inexpensive to convert low-grade marijuana into high-grade hashish oil. YouTube videos already provide easy-to-follow instructions on how to make hashish oil.

 Hemp Talking Points 
 
 
 
 What is "hemp"? 
 
 "Hemp" is not a term found in the Controlled Substances Act (CSA). Historically, "hemp" was simply an alternative term used to refer to the cannabis plant (i.e., an alternative to the Spanish-derived term "marihuana"). However, starting in approximately the late 1990s, the term "hemp" increasingly was used to refer specifically to cannabis grown for industrial purposes. (The term "industrial hemp" is also used in this context.) During this time period, some persons have erroneously asserted that "hemp" was a distinct species from marijuana. Botanically speaking, any plant of the genus "cannabis" constitutes marijuana under the CSA -– regardless of whether the plant is referred to as "hemp," "marijuana," or any other name. 
 
 
 
 Does "hemp" have different psychoactive properties than marijuana? 
 
 The psychoactive properties of a given cannabis plant will depend on the chemical makeup of the plant -– not the name (e.g., "marijuana" or "hemp") that the grower assigns to the plant. The cannabis plant contains roughly 500 different chemicals. The primary psychoactive chemical found in cannabis is tetrahydrocannabinols (THC). Another chemical found in marijuana is cannabidiol (CBD). Among the primary factors that determine the psychoactive properties of a cannabis plant are (1) the amount of THC in the plant and (2) the ratio of THC to CBD in the plant. To oversimplify what is a complex scientific consideration, it is generally the case that the greater the percentage of THC in the plant, the greater the psychoactive effect. However, there is no established minimum threshold amount of THC that a cannabis plant must contain to produce a psychoactive effect. Moreover, the amount of THC that will cause a psychoactive effect will vary among individual users. 
 
 
 
 Cannabis grown for industrial purposes does, generally, have a lower THC content than cannabis grown for smoking. However, from a scientific perspective, there is no maximum or minimum amount of THC that will necessarily be contained in a cannabis plant grown for industrial purposes. The genetic makeup of the plant and the environmental conditions in which it is grown will dictate THC content. 
 
 
 
 For what purposes is "industrial hemp" grown? 
 
 In broadest terms, there are two general categories of "industrial" products that are made from the cannabis plant: fiber-derived products and seed-derived products. From the fiber of the plant, one can produce textiles and paper products. The seeds of the plant can be pressed into oil, which is used as additive in food and beverage products. (It should be noted that the FDA has expressly declined to recognize "hemp seed oil" as generally recognized as safe.) The oil from the seeds is also used as an ingredient in personal care products such as soaps, lotions, and shampoos. Cannabis seeds can also be used in bird feed. 
 
 
 
 Is it legal to grow "hemp" in the United States? 
 
 The CSA permits the cultivation of cannabis for industrial purposes, provided the grower has obtained a DEA registration to do so. This requirement applies with respect to all cannabis plants, regardless of the THC content. Every federal court that has examined this issue has so ruled. Monson v. DEA, 589 F.3d 952 (8th Cir. 2009); United States v. White Plume, 447 F.3d 1067 (8th Cir. 2006); New Hampshire Hemp Council v. Marshall, 203 F.3d 1 (1st Cir. 2000). To obtain such a registration, an applicant must demonstrate, among other things, that it will install security measures consistent with the requirements set forth in the DEA regulations. 
 
 
 
 Does a "hemp" plant with low THC content present any real concerns? 
 
 It is true that, if given a choice, marijuana smokers will seek cannabis with a relatively high THC concentration over the type of cannabis typically grown for industrial purposes. However, as indicated, there is no guarantee that a cannabis plant grown for industrial purposes will not cause a psychoactive effect when smoked. Indeed, there have been reported thefts from "industrial hemp" grow facilities. More significantly, even those cannabis plants that have a relatively low THC concentration provide a substantial source of psychoactive material that would be readily exploited by drug seekers if such plants could be easily acquired. Using a relatively simple and inexpensive process of chemical extraction, low grade cannabis (including so-called "industrial hemp") can be readily converted into a highly potent concentrate known as "hash oil." Anyone can learn how to make hash oil by watching instructional videos on YouTube. 
 
 
 
 Indeed, the illicit production of hash oil appears to be a growing and dangerous trend in the United States, and poses a significant harm to our communities and the environment. Just recently, on February 7, 2013, the U.S. Fire Administration (a component of the Federal Emergency Management Agency) issued a bulletin entitled "Hash Oil Explosions Increasing Across U.S." In this bulletin, which is available atwww.usfa.fema.gov/fireservice/emr-isac/infograms/ig2013/6-13.shtm#1, the U.S. Fire Administration stated, among other things, that explosions in residences and hotels are being traced back to the production of hash oil using butane and that the number of these incidents appears to be increasing. 
 
 
 
 Can one tell "industrial hemp" and marijuana apart? 
 
 It can be extremely difficult to distinguish cannabis grown for industrial purposes from cannabis grown for smoking. This is especially true if law enforcement is attempting to make this determination without entering the premises on which the plants are being grown. 
 
 It should be noted here that "hemp" grown to produce seeds will appear different from "hemp" grown to produce fiber. Plants grown to produce fiber may (depending on the stage of growth) appear taller and stalkier. In contrast, plants grown to produce seeds may appear bushy and thus more difficult to distinguish from plants for smoking. 
 
 
 
 As for the THC content of a cannabis plant, this is impossible to determine without performing a chemical analysis of the particular plant. Further, the THC content can vary significantly from plant-to-plant within a given grow site, meaning that testing one plant cannot be relied upon to prove the THC content of neighboring plants. ||||| 
 
 The House just got a little bit more hemp-friendly. (Creative Commons Attribution License) 
 
 The House is still shell-shocked from the unexpected failure of the Farm Bill last week--the kind of legislation that usually passes smoothly, but in our era of dysfunction, fell victim to a poison pill. As Brad notes, the options going forward include starting over entirely, or even going back to rules written in 1949. 
 
 There are a lot of big reasons to be troubled about this. But at least one thing happened during the writing of the final bill that should be cause for celebration: The House actually accepted an amendment allowing research on industrial hemp. 
 
 Industrial hemp, defined as a particular strain of cannabis with very low levels of THC, is produced in some 30 countries for use in a wide variety of fiber and textile products. But even though nine states have legalized its cultivation, U.S. law still treats it the same as marijuana, which means the Drug Enforcement Administration could throw you in jail for growing it. So the United States has been importing more and more hemp over the years from places like China and Canada--about $11.5 million worth in 2011, according to a March report, with a "highly dedicated and growing demand base." 
 
 That didn't used to be the case. The federal government encouraged the cultivation of hemp fiber during World War II, and it only fell out of favor as anti-drug sentiment rose, before being effectively banned in 1970. Now, it's even illegal to grow the plant for research purposes without explicit permission from the DEA--which is where Rep. Jared Polis (D-Colo.) came in. 
 
 Research is important. Without partnering with academic agronomists, it's hard for farmers to know exactly how to grow an entirely new crop in a given region, and what kinds of yields they can expect. Earlier this year, Colorado State University was considering starting a research program on industrial hemp, but feared losing federal funding because of it. Polis tried to assure the school's Board of Governors that everything would be okay, and encouraged them to seek a waiver from the DEA, which had granted one to the University of Hawaii back in 1999 (and three more since). But the Board wanted some certainty, so Polis introduced an amendment to the farm bill that would legalize cultivation in colleges and universities for research purposes. 
 
 Miraculously, despite last-minute lobbying against it from the DEA, the amendment passed by a vote of 225-200. In light of repeated failures of bills that would legalize industrial hemp production more broadly--one fizzled as an amendment to the Senate farm bill, and a House proposal has been moldering in a subcommittee since April--that's the most significant sign of progress on the federal level that hemp advocates have ever seen. 
 
 It might have a second life sooner than the rest of the House Farm Bill. Polis wants to take that sign of goodwill and tack it on to "any other bill that is germane," such as Agriculture appropriations, or on its own as a standalone bill. "When you have a Congressional majority on any issue, there are a variety of ways you can move forward," Polis says. 
 
 After that's taken care of--along with active support from the likes of Sen. Mitch McConnell (R-Ky.)--a law respecting states' desires to allow hemp production within their own borders looks a little less outlandish.
– It's looking more and more likely that US farmers will be getting back into the hemp-growing business. The latest hopeful sign for advocates came when the House passed an amendment that would make it legal for universities to grow hemp for research purposes—an important step if farmers ever hope to make it a successful agricultural crop, reports the Wonkblog at the Washington Post. The bad news is that the amendment was part of the larger farm bill, which unexpectedly failed. But sponsor Jared Polis of Colorado says he's so encouraged by the 225-200 vote that he will tack the hemp amendment onto some kind of agricultural bill in the near future, or even make it a standalone measure. What he and other advocates—including Mitch McConnell, from farm state Kentucky—are talking about is industrial hemp, which has low levels of THC, the active ingredient in marijuana. It can be used in the manufacture of a wide variety of projects, but the DEA remains worried about its use as a drug. In fact, the Huffington Post obtained the talking points that the DEA circulated to members of Congress as it tried to kill the farm bill amendment. They seemed to fall on deaf ears.
