 Department of Justice Drug Enforcement Administration 21 CFR Part 1310
[Docket No. DEA-320P]
RIN 1117-AB24
 AGENCY: Drug Enforcement Administration (DEA), Department of Justice.
 ACTION: Notice of proposed rulemaking.
 SUMMARY: The Drug Enforcement Administration (DEA) is proposing to control the chemical precursor ergocristine as a List I chemical under the Controlled Substances Act (CSA). Clandestine laboratories are using this 
                        ( print page 8288)
                        chemical as a substitute for the List I chemicals ergotamine and ergonovine to illicitly manufacture the schedule I controlled substance lysergic acid diethylamide (LSD). If finalized as proposed, handlers of ergocristine would be subject to the chemical regulatory provisions of the CSA and its implementing regulations, including 21 CFR parts 1309, 1310, 1313, and 1316. This rulemaking does not propose the establishment of a threshold for domestic and international transactions of ergocristine. As such, all transactions involving ergocristine, regardless of size, would be regulated. This rulemaking also proposes to specify that chemical mixtures containing ergocristine will not be exempt from regulatory requirements at any concentration. Therefore, all transactions of chemical mixtures containing any quantity of ergocristine would be regulated and subject to control under the CSA if this rule is finalized as proposed.

Background Lysergic acid diethylamide (LSD) is a synthetic schedule I hallucinogen. It is the most potent hallucinogen known and only microgram amounts are required to produce overt hallucinations. LSD has been abused for its hallucinogenic properties since the 1960s. It induces a heightened awareness of sensory input that is accompanied by an enhanced sense of clarity, but reduced ability to control what is experienced. The LSD “trip” is composed of perceptual and psychic effects. A user may experience the following perceptual effects: Visual distortion in the size and shape of objects, movements, color, sound, touch, and the user's own body image. The user may report “hearing colors” or “seeing sounds.” The psychic effects experienced by the user may include feelings of obtaining true insight, intensified emotions, sudden and dramatic mood swings, impairment of attention, concentration and motivation, distortion of time, and depersonalization. High doses of LSD can induce a “bad trip” characterized by intense anxiety or panic, confusion, and combative behaviors. After a LSD trip, a user may also experience fatigue, acute anxiety, or depression for 12 to 24 hours. LSD is commonly abused by teenagers and young adults in connection with “raves,” nightclubs, and concert settings. LSD is most commonly found in the form of small squares of paper, called blotter, that are generally decorated with artwork or designs, perforated, soaked in liquid LSD solution, and dried. Each square represents one dose of LSD. There have been some instances of blotter paper being found impregnated with hallucinogens other than LSD. For example, the hallucinogens 2,5-dimethoxyamphetamine (DMA) and 4-bromo-2,5-dimethoxyamphetamine (DOB) have been found on blotter paper passed off as LSD. Other forms of LSD include tablets (known as microdots), gelatin squares (known as window pane), and impregnated sugar cubes. LSD has also been available in gel wraps which look like “bubble-wrap” packing material, and are blue in color. LSD is also distributed in liquid form which often is packaged in small bottles typically sold as breath drops. Additionally, LSD has been embedded in candy such as “Gummy Worms,” “Sweet Tarts,” “Smarties,” and “Pez.” The most common venues for retail LSD 
                    ( print page 8289)
                    distribution are “raves,” dance clubs, and concerts. According to the National Forensic Laboratory Information System (NFLIS), Federal, State, and local forensic laboratories analyzed 1,785 and 1,368 exhibits of LSD in 2000 and 2001, respectively. In 2002, the number of LSD exhibits dropped dramatically to 198 due to the seizure of a large clandestine LSD laboratory in Kansas. The number of LSD samples analyzed by Federal, State, and local forensic laboratories remained low for 2003 and 2004 with 362 and 338 LSD exhibits, respectively. However, there appears to be a slight increasing trend seen in 2005, 2006 and 2007, with 521, 590, and 844 exhibits reported, respectively. This trend appears to carry over into 2008 since NFLIS data, entered as of December 29, 2008 already documents 839 LSD exhibits. Control Status Lysergic acid diethylamide is in schedule I of the CSA (21 U.S.C. 812). LSD precursors, lysergic acid and lysergic acid amide, are both schedule III controlled substances (21 U.S.C. 812(b)). The LSD precursors ergotamine and ergonovine are regulated as List I chemicals under the CSA. Illicit Production of LSD LSD has been manufactured illegally since the 1960s. A limited number of chemists, probably less than a dozen, are believed to be manufacturing nearly all of the LSD available in the United States. Clandestine laboratory operators must adhere to precise and complex production procedures, and production of LSD is relatively difficult. LSD has historically been produced from lysergic acid, which is made from ergotamine or ergonovine, substances derived from an ergot fungus on rye, or from lysergic acid amide, a chemical found in morning glory seeds. Although theoretically possible, manufacture of LSD from morning glory seeds is not economically feasible and these seeds never have been found to be a successful starting material for LSD production. The List I chemicals ergotamine and ergonovine are not widely available in the United States, and their purchase by other than established pharmaceutical firms is suspect. Therefore, ergotamine and/or ergonovine used in clandestine LSD laboratories are believed to have been acquired from sources located abroad. Only a small amount of ergotamine or ergonovine is required to produce LSD in large batches. For example, 25 kilograms of ergotamine tartrate can produce five or six kilograms of pure LSD crystal that, under ideal circumstances, could be processed into 100 million dosage units. Thus, clandestine LSD manufacturers need import only a small quantity of precursor material. Movement to Ergocristine as LSD Precursor and Largest LSD Laboratory Ever Seized by DEA Because of the existing CSA regulatory controls on the LSD precursors lysergic acid, lysergic acid amide, ergotamine, and ergonovine, clandestine laboratory operators have sought uncontrolled sources of precursor material for the production of LSD. This has led to the illicit utilization of the precursor chemical ergocristine as a direct substitute for ergotamine and ergonovine for the illicit production of LSD. In fact, the largest clandestine LSD laboratory ever seized by DEA utilized ergocristine as the LSD precursor. Recipes documenting procedures for utilizing ergocristine in LSD synthesis are easily found on the Internet. In late 2000, in the largest clandestine LSD laboratory seizure ever made by the DEA, agents seized approximately 41.3 kilograms (90.86 pounds) of LSD, manufactured in a clandestine laboratory set up in a missile silo near Wamego, Kansas. On November 6, 2000, two clandestine laboratory operators were moving the illegal laboratory when they were arrested. The clandestine laboratory operators utilized the chemical ergocristine as the unregulated source of precursor material for the production of the LSD. A total of 19 kilograms of ergocristine was seized. According to court testimony, the two defendants previously clandestinely manufactured LSD in Santa Fe, New Mexico, where every five weeks the clandestine laboratory produced about 2.2 pounds of LSD, approximately 10 million doses that cost less than one cent a dose to produce and would sell for as much as $10 a dose. According to court testimony, the LSD was shipped to California and later to Europe for distribution. The El Paso Intelligence Center's National Seizure System data show that five clandestine LSD laboratories have been seized since 2001. According to law enforcement reporting, the seized laboratories were operated by a small number of experienced chemists and were of limited capacity: three of which produced less than two ounces, and two of which produced between two and eight ounces per batch. Availability of the Precursor Chemical DEA has determined that ergocristine is readily available from commercial chemical suppliers. DEA has identified at least three suppliers of ergocristine, of which one distributor is located domestically; the other two are based in Germany and the Czech Republic. The ergocristine used by the clandestine laboratory operator arrested in conjunction with the November 2000, clandestine LSD laboratory in Wamego, Kansas, was obtained through a chemical supplier in Germany who obtained the ergocristine from a chemical source firm operating out of the Czech Republic. In the 2005 International Narcotics Control Board (INCB) report titled “Precursors and Chemicals Frequently Used in the Illicit Manufacture of Narcotic Drugs and Psychotropic Substances,” the INCB reported that in response to Czech authorities expression of concern over orders for ergocristine, INCB scrutiny over such shipments led to the one kilogram seizure of ergocristine by Panamanian authorities in early 2005. The INCB further reported that following the seizure, a further order was received from the Netherlands Antilles. The shipment of ergocristine was followed and a clandestine LSD laboratory identified. In that report, the INCB urged governments to exercise vigilance in regard to shipments of ergot alkaloids (such as ergocristine) and related substitutes not under international control. This rule proposes the addition of both domestic and import/export controls on ergocristine (and its salts). Such controls are deemed necessary for law enforcement to identify domestic and international transactions in ergocristine, due to growing concerns regarding its use for the illicit manufacture of LSD. Regulation of Ergocristine as a List I Chemical The CSA, specifically 21 U.S.C. 802(34) and 21 U.S.C. 802(35), and its implementing regulations at 21 CFR 1310.02(c), provide the Attorney General with the authority to specify, by regulation, additional chemicals as “listed chemicals” if they are used in the manufacture of a controlled substance in violation of the CSA, and are important to the manufacture of the controlled substance. Ergocristine is being used in clandestine laboratories as the precursor material for the illicit manufacture of the schedule I controlled substance LSD. This rule proposes the regulation of ergocristine as a List I 
                    ( print page 8290)
                    chemical because DEA finds that it is used in the illicit manufacture of the controlled substance LSD and is important to the illicit manufacture of the controlled substance LSD. If finalized as proposed, handlers of ergocristine will become subject to the chemical regulatory provisions of the CSA, including 21 CFR parts 1309, 1310, 1313, and 1316. This rulemaking does not propose the establishment of a threshold for domestic and import transactions of ergocristine pursuant to the provisions of 21 CFR 1310.04(g). Due to the high potency of LSD, even a single gram (
                    *i.e.,*
                     1/28th of an ounce) of ergocristine can be used illicitly to make thousands of dosage units of LSD. Therefore, DEA is proposing that all ergocristine transactions, regardless of size, shall be regulated transactions as defined in 21 CFR 1300.02(b)(28). As such, if finalized as proposed, all ergocristine transactions will be subject to recordkeeping, annual manufacturer reporting of inventory and use data, import/export controls, and other CSA chemical regulatory requirements. Chemical Mixtures Containing Ergocristine This rulemaking also proposes that chemical mixtures containing ergocristine not be exempt from regulatory requirements at any concentration, unless an application for exemption of a chemical mixture is submitted by an ergocristine manufacturer and the application is reviewed and accepted by DEA under 21 CFR 1310.13 (Exemption by Application Process). Since even a small amount of ergocristine is able to make a significant amount of LSD, the control of chemical mixtures containing any amount of ergocristine is necessary to prevent the illicit extraction, isolation, and use of the ergocristine. Therefore, all chemical mixtures containing any quantity of ergocristine will be subject to CSA control, if this rule is finalized as proposed, unless the ergocristine manufacturer is granted an exemption by the application process discussed below. If finalized, this proposed rule will modify the Table of Concentration Limits in 21 CFR 1310.12(c) to reflect the fact that chemical mixtures containing any amount of ergocristine are subject to CSA chemical control provisions. Exemption by Application Process DEA has implemented an application process to exempt chemical mixtures from the requirements of the CSA and its implementing regulations (21 CFR 1310.13). Under the application process, manufacturers may submit an application for exemption for those mixtures that do not qualify for automatic exemption. Exemption status can be granted if DEA determines that the mixture is formulated in such a way that it cannot be easily used in the illicit production of a controlled substance and that the listed chemical cannot be readily recovered (i.e., it meets the conditions in 21 U.S.C. 802(39)(A)(vi)). Requirements for Handling List I Chemicals If finalized as proposed, the designation of ergocristine as a List I chemical will subject ergocristine handlers to all of the regulatory controls and administrative, civil, and criminal sanctions applicable to the manufacture, distribution, importing, and exporting of a List I chemical. Upon publication of a final rule, persons potentially handling ergocristine, including regulated chemical mixtures containing ergocristine, will be required to comply with the following List I chemical regulations: *Registration.*
                     Any person who manufactures, distributes, imports, or exports a List I chemical, or proposes to engage in the manufacture, distribution, importation, or exportation of a List I chemical, must obtain a registration pursuant to the CSA (21 U.S.C. 822, 957). Regulations describing registration for List I chemical handlers are set forth in 21 CFR part 1309. Consistent with 21 CFR parts 1309 and 1310, separate registrations will be required for manufacturing, distribution, importing, and exporting of ergocristine. Different locations operated by a single entity require separate registration if any location is involved with the manufacture, distribution, importation, or exportation of ergocristine. Further, a separate registration is required for each principal place of business at one general physical location where List I chemicals are manufactured, distributed, imported, or exported by a person (21 CFR 1309.23). Any person manufacturing, distributing, importing, or exporting an ergocristine chemical mixture will be subject to the registration requirement under the CSA as well. DEA notes that warehouses are exempt from the requirement of registration and may lawfully possess List I chemicals, if the possession of those chemicals is in the usual course of business (21 U.S.C. 822(c)(2), 21 U.S.C. 957(b)(1)(B)). For purposes of this exemption, the warehouse must receive the List I chemical from a DEA registrant and shall only distribute the List I chemical back to the DEA registrant and registered location from which it was received. All other activities conducted by a warehouse do not fall under this exemption; a warehouse that distributes List I chemicals to persons other than the registrant and registered location from which they were obtained is conducting distribution activities and is required to register as such (21 CFR 1309.23(b)(1)). Upon publication of a final rule, any person manufacturing, distributing, importing, or exporting ergocristine or a chemical mixture containing ergocristine will become subject to the registration requirement under the CSA. DEA recognizes, however, that it is not possible for persons who are subject to the registration requirement to immediately complete and submit an application for registration and for DEA to immediately issue registrations for those activities. Therefore, to allow continued legitimate commerce in ergocristine, DEA is proposing to establish in 21 CFR 1310.09 a temporary exemption from the registration requirement for persons desiring to engage in activities with ergocristine, provided that DEA receives a properly completed application for registration on or before 30 days after publication of a Final Rule implementing regulations regarding ergocristine. The temporary exemption for such persons will remain in effect until DEA takes final action on their application for registration or application for exemption of a chemical mixture. The temporary exemption applies solely to the registration requirement; all other chemical control requirements, including recordkeeping and reporting, would become effective on the effective date of the Final Rule. Therefore, all transactions of ergocristine and chemical mixtures containing ergocristine will be regulated while an application for registration or exemption is pending. This is necessary because not regulating these transactions could result in increased diversion of chemicals desirable to drug traffickers. Additionally, the temporary exemption does not suspend applicable federal criminal laws relating to ergocristine, nor does it supersede State or local laws or regulations. All handlers of ergocristine must comply with applicable State and local requirements in addition to the CSA regulatory controls. *Records and Reports.*
                     The CSA (21 U.S.C. 830) requires that certain records be kept and reports be made with respect to listed chemicals. Regulations describing recordkeeping and reporting requirements are set forth in 21 CFR part 1310. Pursuant to 21 CFR 1310.04, a record must be made and maintained 
                    ( print page 8291)
                    for two years after the date of a transaction involving a listed chemical, provided the transaction is a regulated transaction. Each regulated bulk manufacturer of a listed chemical will be required to submit manufacturing, inventory, and use data on an annual basis (21 CFR 1310.05(d)). Existing standard industry reports containing the required information will be acceptable, provided the information is readily retrievable from the report. Title 21 CFR 1310.05(a) requires that each regulated person shall report to DEA any regulated transaction involving an extraordinary quantity of a listed chemical, an uncommon method of payment or delivery, or any other circumstance that the regulated person believes may indicate that the listed chemical will be used in violation of the CSA and its corresponding regulations. Persons are also required to report any proposed regulated transaction with a person whose description or other identifying characteristics the Administration has previously furnished to the regulated person; any unusual or excessive loss or disappearance of a listed chemical under the control of the regulated person; any in-transit loss in which the regulated person is the supplier; and any domestic regulated transaction in a tableting or encapsulating machine. *Import/Export.*
                     All imports, exports, and international transactions of a listed chemical shall comply with the CSA import and export provisions including 21 U.S.C. 957 and 971. Regulations for importation and exportation of List I chemicals are described in 21 CFR part 1313. *Security.*
                     All applicants and registrants shall provide effective controls against theft and diversion of chemicals as described in 21 CFR 1309.71. *Administrative Inspection.*
                     Places, including factories, warehouses, or other establishments and conveyances, where registrants or other regulated persons may lawfully hold, manufacture, distribute, dispense, administer, or otherwise dispose of a regulated chemical/chemical mixture or where records relating to those activities are kept or required to be kept, are controlled premises as defined in 21 CFR 1316.02(c). The CSA (21 U.S.C. 880) allows for administrative inspections of these controlled premises as provided in 21 CFR 1316 Subpart A. Regulatory Certifications Regulatory Flexibility Act and Small Business Concerns The Deputy Administrator hereby certifies that this rulemaking has been drafted in accordance with the Regulatory Flexibility Act (5 U.S.C. 601-612). DEA has been able to identify only one U.S. distributor that lists ergocristine among its products. Because most of the firm's product source appears to be located outside the U.S. and because DEA has not been able to identify any U.S. manufacturer that produces a product containing ergocristine, DEA does not consider it likely that this domestic distributor would be subject to the rule, unless they imported ergocristine. The only probable legitimate commerce in this chemical appears to be the use of ergocristine as precursor material for the synthesis of a research compound. If used for this purpose, then there would be a registration and recordkeeping requirement for this distributor to import the ergocristine. Such use would likely be extremely limited. Therefore, the Deputy Administrator certifies that this rule will not have a significant economic impact on a substantial number of small entities. Executive Order 12866 The Deputy Administrator certifies that this rulemaking has been drafted in accordance with the principles in Executive Order 12866 Section 1(b). It has been determined that this is “a significant regulatory action.” Therefore, this action has been reviewed by the Office of Management and Budget. DEA has not conducted an economic analysis of the proposed rule because DEA has been able to identify only one company with a U.S. address that lists ergocristine among its products. DEA was able to identify only two foreign firms that list ergocristine as a product. These firms appear to sell ergocristine as an active pharmaceutical ingredient, but a search of the Food and Drug Administration's database of approved drugs did not identify any drug with ergocristine as an active ingredient. Consequently, DEA does not believe that at this time any firm conducting legitimate business is likely to have to comply with the rule. Executive Order 12988 This regulation meets the applicable standards set forth in Sections 3(a) and 3(b)(2) of Executive Order 12988, Civil Justice Reform. Executive Order 13132 This rulemaking does not preempt or modify any provision of state law; nor does it impose enforcement responsibilities on any state; nor does it diminish the power of any state to enforce its own laws. Accordingly, this rulemaking does not have federalism implications warranting the application of Executive Order 13132. Unfunded Mandates Reform Act of 1995 This rule will not result in the expenditure by state, local, and tribal governments, in the aggregate, or by the private sector, of $120,000,000 or more (adjusted for inflation) in any one year, and will not significantly or uniquely affect small governments. Therefore, no actions were deemed necessary under the provisions of the Unfunded Mandates Reform Act of 1995. Congressional Review Act This rule is not a major rule as defined by Section 804 of the Congressional Review Act/Small Business Regulatory Enforcement Fairness Act of 1996 (Congressional Review Act). This rule will not result in an annual effect on the economy of $100,000,000 or more; a major increase in cost or prices; or significant adverse effects on competition, employment, investment, productivity, innovation, or on the ability of United States-based companies to compete with foreign-based companies in domestic and export markets.
