Secobarbital will impair motor functions like a mofo.
Secobarbital sodium (marketed by Eli Lilly and Company under the brand name Seconal) is a barbiturate derivative drug that was patented in 1934 in the US. It possesses anaesthetic, anticonvulsant, anxiolytic, sedative, and hypnotic properties. In the United Kingdom, it was known as Quinalbarbitone.
Secobarbital was widely misused in the 1960s and 1970s, and accidental overdose was associated with the drug. It was linked with the death of Judy Garland where the postmortem found that her blood contained the equivalent of ten 1.5-grain (97 mg) Seconal capsules.
