    History & Culture

    Methylmethaqualone is a designer drug analogue of methaqualone that appears to have emerged on the German black market during the late 1990s. The compound was made illegal in Germany in 1999, and around the same time, the United States Drug Enforcement Administration listed it as a "drug of forensic interest." Beyond these regulatory actions, very little documented information about this substance's history or cultural context is available.

    Tolerance & Pharmacokinetics

    drugs.wiki

    No tolerance chart. Our decay curves for these drugs were estimates, and a curve can make tolerance look longer-lasting than it is, which is the dangerous direction.

    How fast tolerance to these drugs fades after a break has not been measured well enough to draw, so don't count on a dose you used to take still being safe: after time off, start with a much smaller amount and don't use alone. Mixing sedatives with each other, with alcohol or with opioids sharply raises the risk of a fatal overdose. If you've been using regularly, don't stop suddenly: withdrawal from benzodiazepines, alcohol or GHB/GBL can cause seizures or delirium, so get medical help to cut down gradually.

    Effect Sentiment Distribution

    Confidence Distribution

    Each bar is the share of reports mentioning the effect; its whisker, and the band on the rows below, is the 95% interval: where the share could plausibly be with other reports of the same kind.

    Too few reports for bars: these effects come from 3 single-substance Erowid reports, and a bar is drawn only from 20 reports or more. With fewer, a percentage cannot tell a common effect from a rare one. Counts are shown instead. Why 20?
