Methylmethaqualone (MMQ) is an analogue of methaqualone which has similar sedative and hypnotic properties to its parent compound, and is around the same potency. Methylmethaqualone differs from methaqualone by 4-methylation on the phenyl ring. It was made illegal in Germany in 1999 and listed by the DEA as a "drug of forensic interest" at about the same time, but little other information is available, it would appear that this compound was sold on the black market in Germany as a designer drug analogue of methaqualone.[1]

Animal studies of methylmethaqualone have shown it to produce convulsions at only slightly above the effective sedative dose,[2] and anecdotal reports from human users have confirmed that it can have a pro-convulsive effect, which could potentially make this compound particularly hazardous if taken in excessive doses.
