[107] On 24 December 1912, Merck filed two patent applications that described the synthesis and some chemical properties of MDMA[108] and its subsequent conversion to methylhydrastinine. なるほどwifiは、「読んでくださる方一人一人が最適なネット回線を選べるような情報を提供すること」を運営理念として掲げ、読者様を第一に考えるネット回線の総合メディアサイトです。, 主に紹介しているネット回線は、近頃主流の「ポケットwifi」「WiMAX」「光回線」です。その他、今後使う人が増えていくであろう「民泊WiFi」や「どんなときもWIFI」「Mugen WiFi」などについても紹介しています。, 4月10日に容量無制限で人気のクラウドWiFi「Mugen WiFi」がサービス停止となりました。サービス停止の要因は、回線提供元の事情とのことです。, これに伴い、「どんなときもWiFi」を始めとしたクラウドWiFiやソフトバンクSIMを利用した大容量WiFiは、全てのサービスが停止となる予定です。, そのため、現状ポケットWiFi業界の勢力図は「WiMAX一択」となりました。ポケットWiFiを契約するなら、一番お得なWiMAX「Broad WiMAX」がおすすめです。, 私たちは、メディアの成長には「読んで良かった」と思える情報を提供することが一番だと考えます。そのため、なるべく本音の嘘偽り無い内容でネット回線のレビュー記事を書いています。, また、なるほどwifiを読んでくださる方々にメリットを提供できるよう、ネット回線を提供する企業様に月額料金やキャッシュバック額などの交渉を行う事もあります。, 例えばブロードワイマックスでは、交渉の結果、なるほどwifi限定で「現金1万円」のキャッシュバックキャンペーンを行えることになりました。, なるほどwifiは、ネット回線メディアの中では少ない「読者様第一」のメディアを目指しています。ネット回線の契約で「騙された」「損をした」など、後悔する方を1人でも減らせれるように正しい情報を発信していきます！, ポケットWi-Fiとは、元々はY!mobileのモバイルWiFiを指す商標でした。ですが、一般的には「外で使えるモバイルWiFi全般」を指してポケットWiFiと呼ばれています。, そのため、なるほどwifiでも「Y!mobileのPocket WiFi」「ソフトバンクSIMのWiFi」「どんなときもwifiなどのクラウドSIM WiFi」などをひとまとめにして「ポケットWiFi」と記述しています。, ポケットWiFiがあれば、家でも外でも場所を気にせずネットに接続できます。そのため、「外で仕事をする人」「外でゲームをする人」などに人気があります。, 数あるポケットWiFiの中でも、現在は「無制限ポケットWiFi」が人気です。月間容量が無制限で速度制限リスクが低いWiFiのことですね！, これからポケットWiFiを契約するようなら、「無制限ポケットWiFi」の中から自分に合ったポケットWiFiを選ぶのがおすすめです。, 今ポケットWiFiを契約するなら、月間容量無制限で通信速度も速い「Broad WiAMX」がおすすめです。, Broad WiMAXは、WiMAXの中でも月額の安さが売りのサービスです。さらに、なるほどWiFi限定で現金1万円キャッシュバックを行なっており業界最安値のWiMAXなんです。, 完全無制限のクラウドWiFiや、月間300GBの大容量WiFiがサービス停止となった今、最もおすすめのポケットWiFiとなります。, 現金1万円キャッシュバック詳細はこちら※上記URLリンク先が表示されていれば現金1万円を受け取り可能です！, WiMAXとは持ち運びできるモバイルWi-Fiのことです。上記表のように、数あるモバイルWi-Fiルーターの中の種類の1つということですね。持ち運びができるWi-Fi＝WiMAXではないので注意しましょう。, WiMAXは「Broad WiMAX」「GMOとくとくBB」「JP WiMAX」などたくさん種類があるように思われがちですが、WiMAXの性能自体はどこも同じです。料金やサポート面が異なるだけなので、なるべく安くてサポートが良いプロバイダ（申込窓口）で契約するのがポイントです！, WiMAXについてさらに詳しく知りたい方は「WiMAX(ワイマックス)とは?初心者が知るべき１０のデメリットメリット!」をチェックしてみてください。, ちなみに、なるほどwifiが最もおすすめするWiMAXは「BroadWiMAX」です。下記では、なるほどwifi限定で開催しているBroadWiMAXのキャンペーンを解説しています。是非、チェックしてみてください！, ポケットWiFiの中でも一番おすすめの「WiMAX」ですが、 WiMAXを選ぶ時は３年間の支払い総額が安いことを基準に選びましょう。, WiMAXは、「UQ WiMAX」が提供するサービスを代理店各社が色をつけて販売する「MVNO形式」のWiFiです。そのため、回線品質は各社同じです。, 違うのは「料金」や「サポート」だけですので、「３年間の支払い総額が安いWiMAX」が最もお得なWiMAXであると言えます。, そのため、特にこだわりが無いようでしたら３年間の支払い総額が圧倒的最安値の「Broad WiMAX」を契約するのが一番お得です！, Broad  WiMAXを契約して現金１万円を受け取る！※上記URLリンク先が表示されていれば現金1万円を受け取り可能です！, 月額料金・契約期間・キャッシュバックなど、自分の好みの条件に当てはまるWiMAXを検索できる「絞り込み検索」を用意しました。, 下記条件の好きな項目にチェックを入れると、その条件に当てはまるWiMAXが表示されます。自分の基準でWiMAXを捜したいときに活用してください！, WiMAXよりも速度が倍以上速いのが光回線です。WiMAXのように速度制限がないので動画視聴をたっぷりしたい方、パソコンでの作業が多い方、家族全員で使いたい方に特におすすめです。, 「スマホのキャリアと合わせて使う」「戸建て・マンション用で最適な光回線を選ぶ」「住んでいる地域で最安のものを使う」などを意識すればお得に光回線を使うことができるので、料金面はモバイルWi-Fiとほとんど変わらないと言っていいでしょう。, ただ、光回線を使うには工事が必要なので今すぐ自宅でWi-Fiを使いたい方はWiMAXのようなモバイルWi-Fiがおすすめです。, 光回線についてさらに詳しく知りたい方は「【元販売員が語る光回線の全て！】2021年2月のおすすめを徹底比較！」をチェックしてみてください。, 置くだけwifiとは、「モバレコエアー」「ソフトバンクエアー」のようなモバイル回線を利用した自宅用のwifiルーターのことです。, 工事不要で即日利用開始することができますし、ライトな利用であれば光回線と遜色なくインターネットを利用できます。, 置くだけwifiは、上記のような特徴から「一人暮らしの人」「Web検索ができれば十分な人」などから近頃人気のWiFiです。, 料金的な話をすると、光回線よりも1,000円程度月額が安く非常にお得な料金設定になっています。, もし、インターネットをWeb閲覧・簡単な動画視聴などでしか利用しないようでしたら是非置くだけwifiの利用も検討してみてください。, 置くだけwifiの契約を検討しているようでしたら、月額が最もお得な「モバレコエアー」の契約をおすすめします。, モバレコエアーはソフトバンクエアーと全く同じサービス内容でありながら、２年間の平均月額が800円近く安い置くだけwifiです。, また、同じく置くだけwifiとして人気の「WiMAX L02」と比較すると平均月額が1,000円近く安くなるんですよ！, いまなら「17,000円」の高額キャッシュバックも受け取れて２年総額が「49,508円」と激安価格となっています。置くだけwifiを契約するならモバレコエアー1択ですね！, 1日〜1ヶ月間など短期間だけ使いたい時におすすめなのが「レンタルWiFi」です。レンタルWiFiは1日単位でレンタルできるWiFiなので、長期間の契約不要でお得に使えます。, 例えば「イベントで3日だけモバイルWiFiを使いたい」「1週間の国内旅行でWiFiを使いたい」などの場合に、とてもお得にWiFiを使うことができます。, 当サイトでは、「入院におすすめのWiFi」や「一時帰国におすすめのWiFi」など、場合別におすすめのレンタルWiFiを紹介しています。, また、【15社比較】国内向けモバイルレンタルWiFiおすすめランキング!の記事で全般的におすすめのレンタルWiFiを紹介しているのでこちらも参考にしてみてください！, なるほどwifiでは「WiFiレンタルどっとこむ」様とコラボレーションして、限定価格でレンタルWiFIをレンタルできます！, 例えば、1日10GB使えるE5388が1ヶ月4,980円でレンタルできます。1日10GB端末の業界相場は6,500円前後なので相場より1500円安い激安価格です。, その他、1日1GBや月間5GBなどの端末も相場よりも安くレンタルできます。最も割引き率が高いWiFiだと、通常価格と比較して1年間で21,600円も安くレンタルできます。, レンタルWiFiを契約するなら、なるほどwifi経由でWiFiレンタルどっとこむを利用するのが最もお得なので是非一度チェックしてみてください！, WiFiレンタルどっとこむの公式HPはこちら当サイトのリンク限定で公式HPよりも月額1,800円安くレンタルできます！, ※クラウドWiFiは、今後全てのサービスが停止する予定のため比較軸から削除しました。, 「どんなときもWiFi」を始めとしたクラウドWiFiやソフトバンクSIMを利用した大容量WiFiは、, ポケットWiFiを契約するなら、一番お得なWiMAX「Broad WiMAX」がおすすめです。, 一般的には「外で使えるモバイルWiFi全般」を指してポケットWiFiと呼ばれています。, なるほどWiFi限定で現金1万円キャッシュバックを行なっており業界最安値のWiMAX, 完全無制限のクラウドWiFiや、月間300GBの大容量WiFiがサービス停止となった今、最もおすすめのポケットWiFi, 下記条件の好きな項目にチェックを入れると、その条件に当てはまるWiMAXが表示されます。, 上記のような特徴から「一人暮らしの人」「Web検索ができれば十分な人」などから近頃人気のWiFiです。, ソフトバンクエアーと全く同じサービス内容でありながら、２年間の平均月額が800円近く安い, いまなら「17,000円」の高額キャッシュバックも受け取れて２年総額が「49,508円」と激安価格となっています。. [116][128][129], Recreational use also increased after several cocaine dealers switched to distributing MDMA following experiences with the drug. Normally there is a high extracellular sodium (Na+) and chloride (Cl–) ion concentration, and low potassium (K+) ion concentration in respect to intracellular concentrations. In some cases, depressive symptoms persist for longer periods. Since the mid-1990s, MDMA has become the most widely used amphetamine-type drug by college students and teenagers. [12][82] MDMA also interacts with drugs which inhibit CYP450 enzymes, like ritonavir (Norvir), particularly CYP2D6 inhibitors. GMOとくとくBBWiMAX 2+の悪い評判は本当?メリット＆デメリット５つで解説! [137] An initial hearing was held on 1 February 1985 at the DEA offices in Washington, D.C. with administrative law judge Francis L. Young presiding. In humans, MDMA binds as an agonist to the following receptors: MDMA has two enantiomers, S-MDMA and R-MDMA. [175] These novel techniques allow police scientists to facilitate the monitoring of illicit distribution networks. [128] Under the brand name "Sassyfras", MDMA tablets were sold in brown bottles. [13] The most serious short-term physical health risks of MDMA are hyperthermia and dehydration. [10][25] In psychotherapeutic settings, MDMA effects have been characterized by infantile ideas, mood lability, and memories and moods connected with childhood experiences. In Canada, MDMA is listed as a Schedule 1[168] as it is an analogue of amphetamine. Albert van Schoor performed simple toxicological tests with the drug in 1952, most likely while researching new stimulants or circulatory medications. [176], A number of ecstasy manufacturers brand their pills with a logo, often being the logo of an unrelated corporation. The United Nations Office on Drugs and Crime stated in its 2014 World Drug Report that US ecstasy retail prices range from US$1 to $70 per pill, or from $15,000 to $32,000 per kilogram. [6], At high doses, MDMA induces a neuroimmune response that, through several mechanisms, increases the permeability of the blood-brain barrier, thereby making the brain more susceptible to environmental toxins and pathogens. Ther. [76], A number of drug interactions can occur between MDMA and other drugs, including serotonergic drugs. [172] By 2014 the EMCDDA reported that the range was more usually between €5 and €10 per tablet, typically containing 57–102 mg of MDMA, although MDMA in powder form was becoming more common.[173]. Once the MDP2P intermediate has been prepared, a reductive amination leads to racemic MDMA (an equal parts mixture of (R)-MDMA and (S)-MDMA).

[119][127] Early MDMA distributors were deterred from large scale operations by the threat of possible legislation. It is also sometimes snorted. Compared to ephedrine, Oberlin observed that it had similar effects on vascular smooth muscle tissue, stronger effects at the uterus, and no "local effect at the eye". While engaged in scheduling debates in the United States, the DEA also pushed for international scheduling. Evidence suggests[94] that the area under the blood plasma concentration versus time curve (AUC) was two to four times higher for the (R)-enantiomer than the (S)-enantiomer after a 40 mg oral dose in human volunteers. [127], After a year of planning and data collection, MDMA was proposed for scheduling by the DEA on 27 July 1984 with a request for comments and objections. In the next month, the World Health Organization identified MDMA as the only substance out of twenty phenethylamines to be seized a significant number of times. [10][50] Reduced gray matter density in certain brain structures has also been noted in human MDMA users. [85], Cortisol, prolactin, and oxytocin quantities in blood serum are increased by MDMA.[6]. [33], MDMA is sometimes taken in conjunction with other psychoactive drugs such as LSD, psilocybin mushrooms, and ketamine, an act called "candy-flipping". In 1959, Wolfgang Fruhstorfer synthesized MDMA for pharmacological testing while researching stimulants. The efficacy of MDMA inhibition is highest towards NET and SERT, and is much less towards DAT. The majority of tablets contain 70–85 mg of MDMA. [6] Serotonin levels typically return to normal within 24–48 hours. [68] MDMA is less addictive than other stimulants such as methamphetamine and cocaine. [84], These monoamine transporters (SERT, NET and DAT) reuptake their respective neurotransmitters via ion gradient. [14], Acute adverse effects are usually the result of high or multiple doses, although single dose toxicity can occur in susceptible individuals. [128]:50[148] Thereafter in the late 1980s, the drug spread alongside rave culture to the UK and then to other European and American cities. This may be due to increased seizures during use and decreased production of the precursor chemicals used to manufacture MDMA. When he tried the drug in 1977, Zeff was impressed with the effects of MDMA and came out of his semi-retirement to promote its use in therapy. Unwitting substitution with other drugs, such as mephedrone and methamphetamine,[153] as well as legal alternatives to MDMA, such as BZP, MDPV, and methylone, are also thought to have contributed to its decrease in popularity. It is therefore possible that no serotonergic neurotoxicity is present in most casual users. [177] Some pills depict logos of products or shows popular with children, such as Shaun the Sheep. Around 1970, Shulgin sent instructions for N-methylated MDA (MDMA) synthesis to the founder of a Los Angeles chemical company who had requested them. [6][12] Severe overdose resulting in death has also been reported in people who took MDMA in combination with certain monoamine oxidase inhibitors,[6][12] such as phenelzine (Nardil), tranylcypromine (Parnate), or moclobemide (Aurorix, Manerix). This individual later provided these instructions to a client in the Midwest. However, the two enantiomers have been shown to exhibit different kinetics. [29][30] The effect of MDMA increasing sociability is consistent, while its effects on empathy have been more mixed. [77] The metabolism may be primarily by cytochrome P450 (CYP450) enzymes CYP2D6 and CYP3A4 and COMT. [114] Urged by Senator Lloyd Bentsen, the DEA announced an emergency Schedule I classification of MDMA on 31 May 1985. [170] Among young adults, 1.8% had used MDMA in the last 1.8% year. Following use, people often feel depressed and tired. [124] [2][3][42] MDMA is also sold in the form of the hydrochloride salt, either as loose crystals or in gelcaps. [13][14] When taken by mouth, effects begin in 30 to 45 minutes and last 3 to 6 hours. [42] In the United States, about 0.9 million people used ecstasy in 2010. Subsequent legally-approved MDMA studies in humans have taken place in the US. [149]:1080 MDMA became one of the four most widely used illicit drugs in the US, along with cocaine, heroin, and cannabis. [71], One study found approximately 15% of chronic MDMA users met the DSM-IV diagnostic criteria for substance dependence. The disposition of MDMA may also be stereoselective, with the S-enantiomer having a shorter elimination half-life and greater excretion than the R-enantiomer. [119][citation needed] No double blind studies had yet been conducted as to the efficacy of MDMA for therapy. Baxter, Ellen W.; Reitz, Allen B. Kolbrich EA, Goodwin RS, Gorelick DA, Hayes RJ, Stein EA, Huestis MA. [52] Long-term exposure to MDMA in humans has been shown to produce marked neurodegeneration in striatal, hippocampal, prefrontal, and occipital serotonergic axon terminals. As of October 2015[update], most of the MDMA in the United States is produced in British Columbia, Canada and imported by Canada-based Asian transnational criminal organizations. In each reuptake cycle, one monoamine, Na+ and Cl– are simultaneously taken inside the cell. [6] The variability of the induced altered state is lower compared to other psychedelics. impaired memory and concentration). Research was stopped "particularly due to a strong price increase of safrylmethylamine", which was still used as an intermediate in methylhydrastinine synthesis. [162], In the United States, MDMA is currently placed in Schedule I of the Controlled Substances Act. [181], InChI=1S/C11H15NO2/c1-8(12-2)5-9-3-4-10-11(6-9)14-7-13-10/h3-4,6,8,12H,5,7H2,1-2H3, A salt of MDMA (typically white) with impurities, resulting in a tan discoloration, Reactors used to synthesize MDMA on an industrial scale in a, Synthesis of MDMA and related analogs from safrole, German patents for MDMA synthesis and the subsequent methylhydrastinine synthesis filed by Merck on 24 December 1912 and issued in 1914. [6] The effects established so far for recreational use of ecstasy lie in the range of moderate to severe effects for serotonin transporter reduction. [12] Concurrent use of MDMA high dosages with another serotonergic drug can result in a life-threatening condition called serotonin syndrome. [10][50] Global reductions in gray matter volume, thinning of the parietal and orbitofrontal cortices, and decreased hippocampal activity have been observed in long term users. Thus, VMAT2 inhibition results in more free cytosolic monoamines like serotonin in the case of serotonergic neurons. Deaths have been reported due to increased body temperature and dehydration. MDMA was also found to have effects on blood sugar levels comparable to high doses of ephedrine. Any other type of sale, use or manufacture is strictly prohibited by law. [24][45] Cases of life-threatening or fatal hyponatremia (excessively low sodium concentration in the blood) have developed in MDMA users attempting to prevent dehydration by consuming excessive amounts of water without replenishing electrolytes.[24][45][46]. However, this effect is not significant in humans. ", "Methylenedioxymethamphetamine (MDMA or 'Ecstasy')", "Methylenedioxymethamphetamine (MDMA, ecstasy)", National Highway Traffic Safety Administration, "3,4-methylenedioxymethamphetamine (MDMA): current perspectives", "The origin of MDMA (ecstasy) revisited: the true story reconstructed from the original documents", "Ecstasy as a Remedy for PTSD? [14] MDMA acts primarily by increasing the activity of the neurotransmitters serotonin, dopamine and noradrenaline in parts of the brain. [64][65] In utero exposure to MDMA is associated with a neuro- and cardiotoxicity[65] and impaired motor functioning. [102] One method is to isomerize safrole to isosafrole in the presence of a strong base, and then oxidize isosafrole to MDP2P. [67] Because MDMA releases dopamine in the striatum, the mechanisms by which it induces ΔFosB in the nucleus accumbens are analogous to other dopaminergic psychostimulants. [12] However, because MDMA excretion and metabolism have nonlinear kinetics,[95] the half-lives would be higher at more typical doses (100 mg is sometimes considered a typical dose[90]). When taken by mouth, effects begin in 30 to 45 minutes and last 3 to 6 hours. Depression, substance use disorders, relationship problems, premenstrual syndrome, and autism were among several psychiatric disorders MDMA assisted therapy was reported to treat. Bill Mandel reported on "Adam" in a 10 June San Francisco Chronicle article, but misidentified the drug as methyloxymethylenedioxyamphetamine (MMDA). [127] The Texas Group advertised "Ecstasy parties" at bars and discos, describing MDMA as a "fun drug" and "good to dance to". As a free base, MDMA is a colorless oil insoluble in water. [112] Following the self-trials of a colleague at the University of San Francisco, Shulgin synthesized MDMA and tried it himself in September and October 1976. [139][141][142] The ban took effect one month later on 1 July 1985[138] in the midst of Nancy Reagan's "Just Say No" campaign.[143][144]. [56] The author noted that oxytocin and D-cycloserine are potentially safer co-drugs in PTSD treatment, albeit with limited evidence of efficacy. Complex, nonlinear pharmacokinetics arise via autoinhibition of CYP2D6 and CYP2D8, resulting in zeroth order kinetics at higher doses. Drugtext – 10 years of ecstasy and other party drug use in Australia: What have we done and what is there left to do? [23] The desired short-term psychoactive effects of MDMA have been reported to include: The experience elicited by MDMA depends on the dose, setting, and user. As a result of several expert witnesses testifying that MDMA had an accepted medical usage, the administrative law judge presiding over the hearings recommended that MDMA be classified as a Schedule III substance. [citation needed] It is classed as a Schedule 9 Prohibited Substance in the country, meaning it is available for scientific research purposes only. At the time, Merck was interested in developing substances that stopped abnormal bleeding. [63], MDMA overdose symptoms vary widely due to the involvement of multiple organ systems. A 1920 Merck patent describes a chemical modification to MDMA. The authors did not evaluate or rate the negative impact of ecstasy on the cognitive health of ecstasy users (e.g. 【2021年2月最新】So-net光キャッシュバックキャンペーン10社を徹底比較! [10], MDMA is known to be metabolized by two main metabolic pathways: (1) O-demethylenation followed by catechol-O-methyltransferase (COMT)-catalyzed methylation and/or glucuronide/sulfate conjugation; and (2) N-dealkylation, deamination, and oxidation to the corresponding benzoic acid derivatives conjugated with glycine. [160][161] An editorial he wrote in the Journal of Psychopharmacology, where he compared the risk of harm for horse riding (1 adverse event in 350) to that of ecstasy (1 in 10,000) resulted in his dismissal as well as the resignation of his colleagues from the ACMD. [6] Among adolescent users in the United States between 1999 and 2008, girls were more likely to use MDMA than boys. [18] In the United States, as of 2017, about 7% of people have used MDMA at some point in their lives and 0.9% have used it in the last year. The essential oil of Ocotea cymbarum, for example, typically contains between 80 and 94% safrole. [117], Psychotherapists who used MDMA believed the drug eliminated the typical fear response and increased communication. [8] MDMA tablets typically have low purity due to bulking agents that are added to dilute the drug and increase profits (notably lactose) and binding agents. [171], In 2008 the European Monitoring Centre for Drugs and Drug Addiction noted that although there were some reports of tablets being sold for as little as €1, most countries in Europe then reported typical retail prices in the range of €3 to €9 per tablet, typically containing 25–65 mg of MDMA. [69][70] Compared with amphetamine, MDMA and its metabolite MDA are less reinforcing. "[165], In the Netherlands, the Expert Committee on the List (Expertcommissie Lijstensystematiek Opiumwet) issued a report in June 2011 which discussed the evidence for harm and the legal status of MDMA, arguing in favor of maintaining it on List I.[165][166][167]. The first confirmed sample was seized and identified by Chicago Police in 1970, see, Syndrome of inappropriate antidiuretic hormone, United States District Court for the Eastern District of Tennessee, European Monitoring Centre for Drugs and Drug Addiction, "Can MDMA play a role in the treatment of substance abuse? [34], As of 2017[update], MDMA has no accepted medical indications. Bibliography of Psychedelic Research Studies. [18] This was broadly similar to the percentage of people who use cocaine or amphetamines, but lower than for cannabis or opioids. [107], Outside of Merck, other researchers began to investigate MDMA. After pharmacological studies, research on MDMA was not continued. in Detroit (Wayne State University), Chicago (University of Chicago), San Francisco (UCSF and California Pacific Medical Center), Baltimore (NIDA–NIH Intramural Program), and South Carolina, as well as in Switzerland (University Hospital of Psychiatry, Zürich), the Netherlands (Maastricht University), and Spain (Universitat Autònoma de Barcelona). [164] Other courts have upheld the sentencing guidelines. [8] The average content of MDMA in a preparation is 70 to 120 mg with the purity having increased since the 1990s. [128] MDMA was openly distributed in Austin and Dallas–Fort Worth area bars and nightclubs, becoming popular with yuppies, college students, and gays. [6] Several forms of memory are impaired by chronic ecstasy use;[13][56] however, the effects for memory impairments in ecstasy users are generally small overall. WX06、W06、WX05、W05、WX04、W04、HOME02、L02、HOME01、L01s、novas, WX06、W06、WX05、W05、WX04、W04、HOME02、L02、HOME01、L01s. [119][145] Later Harvard psychiatrist Lester Grinspoon sued the DEA, claiming that the DEA had ignored the medical uses of MDMA, and the federal court sided with Grinspoon, calling Lawn's argument "strained" and "unpersuasive", and vacated MDMA's Schedule I status. [107][112][113], MDMA may have been in non-medical use in the western United States in 1968. [14][15] MDMA is commonly associated with dance parties, raves, and electronic dance music. Each VMAT2 transports cytosolic monoamines into the vesicle by dissipating proton gradient across the vesicular membrane. MDMA also induces significant norepinephrine release. Over the following years the number of MDMA samples increased, eventually exceeding the number of MDA samples in the early 1980s. "Now sick dealers peddle Shaun the Sheep Ecstasy tablets", "World's first trials of MDMA to treat alcohol addiction set to begin", "MDMA for the treatment of mood disorder: all talk no substance? These monoamines can then be released via monoamine transporters, which have been reversed by MDMA (see below). [42] The market for MDMA in the United States is relatively small compared to methamphetamine, cocaine, and heroin. [92][non-primary source needed]. Conducted at the University of Michigan in Ann Arbor, these investigations were declassified in October 1969 and published in 1973. [60][61][page needed] In addition, MDMA has immunosuppressive effects in the peripheral nervous system and pro-inflammatory effects in the central nervous system. The agency cited increased distribution in Texas, escalating street use, and new evidence of MDA (an analog of MDMA) neurotoxicity as reasons for the emergency measure. The contributions of these metabolites to the psychoactive and toxic effects of MDMA are an area of active research. It is thought that this can result in sustained and higher concentrations of MDMA if the user takes consecutive doses of the drug. [109], Merck records indicate its researchers returned to the compound sporadically. [50][53] Neurotoxic damage to serotonergic axon terminals has been shown to persist for more than two years. [128]:46 In 1985, MDMA use became associated with Acid House on the Spanish island of Ibiza. Although MDMA was not named explicitly in this legislation, the order extended the definition of Class A drugs to include various ring-substituted phenethylamines. [6] In the European Union as of 2018, 4.1% of adults (15–64 years old) have used MDMA at least once in their life, and 0.8% had used it in the last year. Permits for research uses on humans must be approved by a recognized ethics committee on human research.
