SUPPLEMENTARY INFORMATION: On April 4, 2003, the Deputy Administrator
of the DEA published a final rule in the Federal Register amending
Sec. 1308.11(g) of title 21 of the Code of Federal Regulations to
temporarily place AMT and 5-MeO-DIPT (68 FR 16427) into Schedule I of
the CSA pursuant to the temporary scheduling provisions of 21 U.S.C.
811(h). This final rule, which became effective on the date of
publication, was based on findings by the Deputy Administrator that the
temporary scheduling of AMT and 5-MeO-DIPT was necessary to avoid an
imminent hazard to the public safety. The CSA (21 U.S.C. 811(h)(2))
requires that the temporary scheduling of a substance expire at the end
of one year from the date of issuance of the order. However, if
proceedings to schedule a substance pursuant to 21 U.S.C. 811(a)(1) are
pending, the temporary scheduling of a substance may be extended for up
to six months. Under this provision, the temporary scheduling of AMT
and 5-MeO-DIPT, which would expire on April 3, 2004, may be extended to
October 3, 2004. This extension is being ordered by the
[[Page 16839]]
DEA Acting Deputy Administrator in a separate action.
In accordance with 21 U.S.C. 811(b) of the CSA, DEA has gathered
and reviewed the available information regarding the pharmacology,
chemistry, trafficking, actual abuse, pattern of abuse, and the
relative potential for abuse of AMT and 5-MeO-DIPT. The Acting Deputy
Administrator has submitted these data to the Acting Assistant
Secretary for Health, Department of Health and Human Services. In
accordance with 21 U.S.C. 811(b), the Acting Deputy Administrator also
requested a scientific and medical evaluation and a scheduling
recommendation for AMT and 5-MeO-DIPT from the Acting Assistant
Secretary for Health. The Food and Drug Administration (FDA) has
notified the DEA that there are no exemptions or approvals in effect
under 21 U.S.C. 355 of the Food, Drug and Cosmetic Act for AMT and 5-
MeO-DIPT. A search of the scientific and medical literature revealed no
indications of current medical use of AMT and 5-MeO-DIPT in the United
States.
Explanation of Alpha-methyltryptamine and 5-methoxy-N, N-
diisopropyltryptamine
Alpha-methyltryptamine (AMT) and 5-methoxy-N,N-
diisopropyltryptamine (5-MeO-DIPT) are tryptamine (indoleethylamine)
derivatives and share several similarities with the Schedule I
tryptamine hallucinogens such as alpha-ethyltryptamine (AET) and N,N-
dimethyltryptamine (DMT). Several other tryptamines also produce
hallucinogenic/stimulant effects and are controlled as Schedule I
substances under the CSA (bufotenine, diethyltryptamine, psilocybin and
psilocyn). Although tryptamine itself appears to lack consistent
hallucinogenic/stimulant effects, substitutions on the indole ring and
the ethylamine side-chain of this molecule result in pharmacologically
active substances (McKenna and Towers, J. Psychoactive Drugs, 16: 347-
358, 1984). The chemical structures of AMT and 5-MeO-DIPT possess the
critical features necessary for hallucinogenic/stimulant activity. In
drug discrimination studies, both AMT and 5-MeO-DIPT substitute for 1-
(2,5-dimethoxy-4-methylphenyl)-aminopropane (DOM), a phenethylamine-
based hallucinogen in Schedule I of the CSA. The potencies of DOM-like
discriminative stimulus effects of these and several other similar
tryptamine derivatives correlate well with their hallucinogenic
potencies in humans (Glennon et al., Eur. J. Pharmacol. 86: 453-459,
1983).
AMT, besides its full generalization to DOM, also partially mimics
amphetamine and 3,4-methylenedioxymethamphetamine (MDMA) in drug
discrimination tests in experimental animals. AMT increases systolic
and diastolic arterial blood pressures, dilates pupils and produces
strong motor stimulant effects. The behavioral effects of orally
administered AMT (20 mg) in humans are slow in onset, occurring after 3
to 4 hours, and gradually subsiding after 12 to 24 hours, but may last
up to 2 days in some subjects. The majority of the subjects report
euphoria, stimulation, muscle tension, muscle ache, nervous tension,
irritability, restlessness, dizziness, impaired motor coordination,
unsettled feeling in stomach, inability to relax and sleep, and visual
effects such as blurry vision, apparent movement of objects, sharper
outlines, brighter colors, longer after images, and visual
hallucinations. The majority of the subjects equate the effects of a 20
mg dose of AMT to those of 50 micrograms of lysergic acid diethylamide
(LSD). AMT also produces dextroamphetamine-like mood elevating effects
in humans (Hollister et al., J. Nervous Ment. Dis., 131: 428-434, 1960;
Murphree et al., Clin. Pharmacol. Ther. 2: 722-726, 1961).
Similar to other classical hallucinogens, AMT binds to serotonin
receptors. It also inhibits 5-HT uptake, induces catecholamine release
and inhibits monoamine oxidase activity. The available experimental
evidence suggests that both serotonergic and dopaminergic systems
mediate behavioral effects of AMT.
5-MeO-DIPT produces pharmacological effects similar to those of
several Schedule I hallucinogens. The synthesis and preliminary human
psychopharmacology study on 5-MeO-DIPT was first published in 1981
(Shulgin and Carter, Comm. Psychopharmacol. 4: 363-369, 1981).
According to this report, subjective effects of 5-MeO-DIPT are
substantially similar to those of MDMA, 3,4-methylenedioxyamphetamine
(MDA) and 4-Bromo-2,5-dimethoxyphenethylamine (2C-B). 5-MeO-DIPT is an
orally active hallucinogen. Following oral administration of 6-10 mg,
5-MeO-DIPT produces subjective effects with an onset of about 20-30
minutes, a peak at about 1-1.5 hours and duration of about 3-6 hours.
Subjects who have been administered 5-MeO-DIPT are talkative and
disinhibited. 5-MeO-DIPT dilates pupils. High doses of 5-MeO-DIPT
produce nausea, jaw clenching, muscle tension and overt hallucinations
with both auditory and visual distortions. As mentioned above, 5-MeO-
DIPT fully mimics the discriminative stimulus effects of DOM, a
Schedule I hallucinogen. According to the discriminative stimulus
studies conducted by the Drug Evaluation Committee of the College on
Problems of Drug Dependence, 5-MeO-DIPT dose-dependently (0.1-3 mg/kg,
IP) generalizes to LSD with a maximal response of about 70% at doses (3
mg/kg) that severely disrupted responding.
Control of AMT and 5-MeO-DIPT
The abuse of stimulant/hallucinogenic substances in popular all
night dance parties (raves) and in other venues has been a major
problem in Europe since the 1990s. In the past several years, this
activity has spread to the United States. The Schedule I controlled
substance MDMA and its analogues, collectively known as Ecstasy, are
the most popular drugs abused at these raves. Their abuse has been
associated with both acute and long-term public health and safety
problems. These raves have also become venues for the trafficking and
abuse of other substances in place of or in addition to ``Ecstasy.''
AMT and 5-MeO-DIPT belong to such a group of substances.
The abuse of AMT and 5-MeO-DIPT began to spread in 1999. Since that
time, these tryptamines have been encountered by law enforcement
agencies in several states. These substances have been commonly
encountered in tablet, capsule or powder forms. The tablet form often
bears imprints commonly seen on MDMA tablets such as spider, alien head
and ``?'' logos. These tablets also vary in colors such as pink,
purple, red, and orange. The powder in capsule was also found to vary
in colors such as white, off-white, gray, and burnt orange. Data from
law enforcement officials indicate that 5-MeO-DIPT is often sold as
``Foxy'' or ``Foxy Methoxy'', while AMT has been sold as ``Spirals'' at
least in one case. Data gathered from published studies indicate that
these are administered orally at doses ranging from 15-40 mg for AMT
and 6-20 mg for 5-MeO-DIPT.
According to the Florida Department of Law Enforcement (FDLE), the
abuse by teens and young adults of AMT and 5-MeO-DIPT is an emerging
problem. There have been reports of abuse of AMT and 5-MeO-DIPT at
clubs and raves in Arizona, California, Florida, and New York. Many
tryptamine-based substances are illicitly available from United States
and foreign chemical companies and from individuals through the
Internet. There is also
[[Page 16840]]
evidence of attempted clandestine production of AMT and 5-MeO-DIPT in
Nevada, Virginia, and Washington, DC.
According to the data from System to Retrieve Information on Drug
Evidence (STRIDE), Federal law enforcement authorities seized 31 drug
exhibits and filed 13 cases pertaining to the trafficking, distribution
and abuse of AMT during 1999 to 2003. The corresponding STRIDE data for
5-MeO-DIPT included 59 drug exhibits pertaining to 28 cases. AMT drug
seizures included 21 capsules and 1,006 grams of powder, while 5-MeO-
DIPT drug seizures included 11,373 tablets, 560 capsules, and 6,531.6
grams of powder. From 2001 to 2003, National Forensic Laboratory
Information System (NFLIS) registered 10 and 12 cases of AMT and 5-MeO-
DIPT, respectively. AMT drug exhibits included 17 dosage units and 7.53
grams of powder, while 5-MeO-DIPT drug exhibits included 24 capsules, 3
tablets and 14.42 grams of powder. In addition, there have been several
local cases involving trafficking and abuse of AMT and 5-MeO-DIPT.
AMT and 5-MeO-DIPT share substantial chemical and pharmacological
similarities with other Schedule I tryptamine-based hallucinogens in
Schedule I of the CSA. AMT shares pharmacological effects of
amphetamine, a stimulant, and DOM and LSD, the Schedule I
hallucinogens. AMT acts as a stimulant, produces euphoria and increases
heart rate and blood pressure. The evidence suggests that 5-MeO-DIPT
mimics pharmacological effects of MDMA, MDA, and 2C-B, the Schedule I
hallucinogens. It also partially mimics amphetamine effects. The risks
to the public health associated with the above mentioned controlled
substances are well known and documented. AMT and 5-MeO-DIPT, similar
to other tryptamine-or phenethylamine-based hallucinogens, through the
alteration of sensory perception and judgment can pose serious health
risks to the user and the general public. Tryptamine, the parent
molecule of AMT and 5-MeO-DIPT, is known to produce convulsions and
death in animals (Tedeschi et al., J. Pharmacol. Exp. Ther. 126: 223-
232, 1959). Following extensive studies on AMT as a possible
antidepressant drug in 1960s, the Upjohn Company concluded that AMT is
a highly toxic substance and discontinued the clinical studies on this
substance. In fact, there were two recent published case reports
describing the instances of emergency department admissions resulting
from abuse of AMT and 5-MeO-DIPT in 2003 (Long et al., Vet. Human
Toxicol., 45: 149, 2003; Meatherall and Sharma, J. Anal. Toxicol., 27:
313-317, 2003). There has been at least one confirmed death caused by
the abuse of AMT in Florida in 2003. The above data show that the
continued, uncontrolled tablet or capsule production, distribution and
abuse of AMT and 5-MeO-DIPT pose hazards to the public health and
safety. There are no recognized therapeutic uses of these substances in
the United States.
The Acting Deputy Administrator, based on the information gathered
and reviewed by her staff and after consideration of the factors in 21
U.S.C. 811(c), believes that sufficient data exist to support the
placement of AMT and 5-MeO-DIPT into Schedule I of the CSA pursuant to
21 U.S.C. 811(a). The specific findings required pursuant to 21 U.S.C.
811 and 812 for a substance to be placed into Schedule I are as
follows:
(1) The drug or other substance has a high potential for abuse.
(2) The drug or other substance has no currently accepted medical
use in treatment in the United States.
(3) There is a lack of accepted safety for use of the drug or other
substance under medical supervision.
Before issuing a final rule in this matter, the DEA Acting Deputy
Administrator will take into consideration the scientific and medical
evaluation and scheduling recommendation of the Department of Health
and Human Services in accordance with 21 U.S.C. 811(b). The Acting
Deputy Administrator will also consider relevant comments from other
concerned parties.
Interested persons are invited to submit their comments,
objections, or requests for a hearing in writing, with regard to this
proposal. Requests for a hearing should state with particularity the
issues concerning which the person desires to be heard. All
correspondence regarding this matter should be sent to the Drug
Enforcement Administration according to the instructions found in the
Addresses section of this proposed rule. In the event that comments,
objections or requests for a hearing raise one or more questions that
the Acting Deputy Administrator finds warrants a hearing, the Acting
Deputy Administrator shall publish a hearing notice in the Federal
Register summarizing the issues to be heard and setting the time for
the hearing.
Regulatory Certifications
Regulatory Flexibility Act
The Acting Deputy Administrator hereby certifies that this proposed
rule has been drafted in accordance with the Regulatory Flexibility Act
(5 U.S.C. 605(b)), has reviewed this regulation, and by approving it
certifies that this regulation will not have a significant economic
impact on a substantial number of small entities. This proposed rule,
if promulgated, would permanently place AMT and 5-MeO-DIPT into
Schedule I of the Controlled Substances Act.
Executive Order 12866
This proposed rule is not a significant regulatory action for the
purposes of Executive Order (E.O.) 12866 of September 30, 1993. Drug
scheduling matters are not subject to review by the Office of
Management and Budget (OMB) pursuant to provisions of E.O. 12866, Sec.
3(d) (1).
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 Federalism
This proposed rulemaking will not have substantial direct effects
on the States, on the relationship between the national government and
the States, or on the distribution of power and responsibilities among
the various levels of government. Therefore, in accordance with
Executive Order 13132, it is determined that this proposed rulemaking
will not have sufficient federalism implications to warrant the
preparation of a federalism assessment.
Unfunded Mandates Reform Act
This proposed rulemaking will not result in the expenditure by
State, local and tribal governments, in the aggregate, or by the
private sector, of $100,000,000 or more in any one year, and it will
not significantly or uniquely affect small governments. Therefore, no
actions were deemed necessary under provisions of the Unfunded Mandates
Reform Act of 1995.
Small Business Regulatory Enforcement Fairness Act of 1996
This proposed rulemaking is not a major rule as defined by Sec.
804 of the Small Business Regulatory Enforcement Fairness Act of 1996.
This rule will not result in an annual effect on the economy of
$100,000,000 or more; a major increase in costs 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.
