Toxicity
PsychonautWikiThe toxicity profile of mephenaqualone is not well-documented, but it is assumed to be similar to that of methaqualone. Overdosing on mephenaqualone can lead to severe sedation, respiratory depression, and potentially life-threatening symptoms. As with all CNS depressants, combining mephenaqualone with other depressants like alcohol or benzodiazepines significantly increases the risk of overdose and fatal respiratory depression.
