This week on The Tox Lab, we’re taking a closer look at quaaludes and their modern analogues.

Once synonymous with a particular era of drug use, quaaludes have largely disappeared from the illicit market. But have they really gone away? We explore the history of methaqualone, how and why it fell out of use, and what has appeared in its place.

We then dive into a review examining a wide range of methaqualone analogues, focusing on how these substances are described by users, the variability in their effects, and what this means for interpretation.

Join us as we unpack the legacy of quaaludes, the chemistry behind their analogues, and what user experiences can tell us about substances that are often poorly characterised.
