Shorthand term for Mandrax (pronounced "Mandrakes"), a line of highly addictive British pharmaceutical tablets no longer in legal production. They act as barbiturates (or "downers") and were prescribed as sleeping aids in the late 60s and early 70s. They are prevalent on the drug market in many African countries, as well as a few south Asian countries. As Mandrax was initially produced in pill form and meant to be taken orally, many abusers ground up the pills and smoke them with Dagga, because like most other illicit substances, the effects are greatly enhanced when snorted, smoked, consumed in conjunction with alcohol or injected into the bloodstream. Short-term side effects are not much worse than your average anti-depressant (cramps, headaches, emotional problems, etc.) but loss of muscle control (resulting in the user suddenly collapsing) and toxin-induced psychosis have also been found to result from Mandrax use.

Slang for MDMA. "Mandy" is a powder form of the drug ecstacy. Is often preferred to ecstasy pills as MDMA is pure, whilst ecstasy pills are often adulterated. It is a popular drug amongst ravers and people who do not trust the purity of pills, and ecstasy in general has always been associated, often by the police and government, with the underground dance music scene.

Other slang names include "mud".
