The CDSA was updated as a result of the Safe Streets and Communities Act changing amphetamines from Schedule III to Schedule I in March 2012.  MDMA racemate is a partial agonist towards human TAAR1, but this is not physiologically relevant due to low EC50. , MDMA is sometimes taken in conjunction with other psychoactive drugs such as LSD, psilocybin mushrooms, and ketamine, an act called "candy-flipping". , MDMA has become widely known as ecstasy (shortened "E", "X", or "XTC"), usually referring to its tablet form, although this term may also include the presence of possible adulterants or diluents. They described MDMA as inducing "an easily controlled altered state of consciousness with emotional and sensual overtones" comparable "to marijuana, to psilocybin devoid of the hallucinatory component, or to low levels of MDA". Research was stopped "particularly due to a strong price increase of safrylmethylamine", which was still used as an intermediate in methylhydrastinine synthesis.  Results of several studies show the effects of increased empathy with others. MDMA is legally controlled in most of the world under the UN Convention on Psychotropic Substances and other international agreements, although exceptions exist for research and limited medical use.  Most illicit MDMA is synthesized using MDP2P (3,4-methylenedioxyphenyl-2-propanone) as a precursor.  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.  The Commission on Narcotic Drugs added MDMA to Schedule I of the convention on 11 February 1986. 2021.2.09 【カナスム特派員】家は3回建てないと理想が叶わない？ 2021.2.09 【カナスム特派員】「ヴィンテージウイスキー」  Compared with amphetamine, MDMA and its metabolite MDA are less reinforcing.  A scheme for management of acute MDMA toxicity has been published focusing on treatment of hyperthermia, hyponatraemia, serotonin syndrome, and multiple organ failure. , Merck records indicate its researchers returned to the compound sporadically. In 1959, Wolfgang Fruhstorfer synthesized MDMA for pharmacological testing while researching stimulants. In 1953 and 1954, the United States Army commissioned a study of toxicity and behavioral effects in animals injected with mescaline and several analogues, including MDMA.  Some of these symptoms include fatigue, loss of appetite, depression, and trouble concentrating. , Intracellular MDMA can also bind to monoamine oxidase A (MAO-A) as an inhibitor, and thus prevent it from breaking down cytosolic serotonin. 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。.

Later,[when?] When taken by mouth, effects begin in 30 to 45 minutes and last 3 to 6 hours. , The MDMA concentration in the blood stream starts to rise after about 30 minutes, and reaches its maximal concentration in the blood stream between 1.5 and 3 hours after ingestion. , MDMA may have been in non-medical use in the western United States in 1968. , The potential for MDMA to be used as a rapid-acting antidepressant has been studied in clinical trials, but as of 2017 the evidence on efficacy and safety were insufficient to reach a conclusion.  A 2007 analysis estimated MDMA to have a psychological dependence and physical dependence potential roughly three-fourths to four-fifths that of cannabis.  However, there is consistent evidence of structural and functional deficits in MDMA users with high lifetime exposure.  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. , American chemist and psychopharmacologist Alexander Shulgin reported he synthesized MDMA in 1965 while researching methylenedioxy compounds at Dow Chemical Company, but did not test the psychoactivity of the compound at this time. In Canada, MDMA is listed as a Schedule 1 as it is an analogue of amphetamine. Although MDMA was not named explicitly in this legislation, the order extended the definition of Class A drugs to include various ring-substituted phenethylamines.

In psychotherapeutic settings, MDMA effects have been characterized by infantile ideas, mood lability, and memories and moods connected with childhood experiences.  One method is to isomerize safrole to isosafrole in the presence of a strong base, and then oxidize isosafrole to MDP2P. Some drug abuse screening programs rely on hair, saliva, or sweat as specimens.  The magnitude of these impairments is correlated with lifetime MDMA usage and are partially reversible with abstinence. 80% of MDMA is metabolised in the liver, and about 20% is excreted unchanged in the urine.  Sympathomimetic side effects can be managed with carvedilol. It is therefore possible that no serotonergic neurotoxicity is present in most casual users. A 1920 Merck patent describes a chemical modification to MDMA. 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".  The duration of action of MDMA is usually four to six hours, after which serotonin levels in the brain are depleted. , In humans, MDMA increases the amount of serotonin in the synaptic clefts of serotonergic neurons by inhibiting its uptake into neurons and by directly releasing it from the neurons. Each VMAT2 transports cytosolic monoamines into the vesicle by dissipating proton gradient across the vesicular membrane.

Shulgin occasionally used MDMA for relaxation, referring to it as "my low-calorie martini", and gave the drug to friends, researchers, and others who he thought could benefit from it. Likewise, the plasma half-life of (R)-MDMA was significantly longer than that of the (S)-enantiomer (5.8 ± 2.2 hours vs 3.6 ± 0.9 hours).  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.  However, most studies on MDMA and serotonergic neurotoxicity in humans focus on the heaviest users, those who consume more than seven times the average.  Before it was widely banned, it saw limited use in psychotherapy.  The DEA was surprised when a number of psychiatrists, psychotherapists, and researchers objected to the proposed scheduling and requested a hearing. Baxter, Ellen W.; Reitz, Allen B. Kolbrich EA, Goodwin RS, Gorelick DA, Hayes RJ, Stein EA, Huestis MA. Evidence suggests 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.

Some users enjoy the feeling of mass communion from the inhibition-reducing effects of the drug, while others use it as party fuel because of the drug's stimulatory effects. Bill Mandel reported on "Adam" in a 10 June San Francisco Chronicle article, but misidentified the drug as methyloxymethylenedioxyamphetamine (MMDA). While intrigued by reports of psychotherapeutic uses for the drug, the committee viewed the studies as lacking appropriate methodological design and encouraged further research. The immediate adverse effects of MDMA use can include: Other adverse effects that may occur or persist for up to a week following cessation of moderate MDMA use include:, As of 2015[update], the long-term effects of MDMA on human brain structure and function have not been fully determined. Permits for research uses on humans must be approved by a recognized ethics committee on human research. , A small recreational market for MDMA developed by the late 1970s, consuming perhaps 10,000 doses in 1976. In Western Australia under the Misuse of Drugs Act 1981 4.0g of MDMA is the amount required determining a court of trial, 2.0g is considered a presumption with intent to sell or supply and 28.0g is considered trafficking under Australian law.. Thus, VMAT2 inhibition results in more free cytosolic monoamines like serotonin in the case of serotonergic neurons.  Furthermore, it is not clear yet whether "typical" users of MDMA (1 to 2 pills of 75 to 125 mg MDMA or analogue every 1 to 4 weeks) will develop neurotoxic brain lesions.

Concurrent use of MDMA high dosages with another serotonergic drug can result in a life-threatening condition called serotonin syndrome.  The most common salt of MDMA is the hydrochloride salt; pure MDMA hydrochloride is water-soluble and appears as a white or off-white powder or crystal. impaired memory and concentration).
