# Recreational Use
Secobarbital began to be widely abused in the 1960s and 1970s, although with the advent of benzodiazepines, they have become less commonly used.
Secobarbital has acquired many nicknames, the most common being "reds", or "red dillies" (it was originally packaged in red capsules). Another common nickname is "seccies". A less common nickname is "dolls"; this was partly responsible for the title of Jacqueline Susann's novel Valley of the Dolls, whose main characters use secobarbital and other such drugs.
Another popular brand of barbiturate pill Tuinal contained a combination of secobarbital and amobarbital but is now rarely prescribed due to problems with abuse and overdose.

## Cause of Death of Charles Boyer

## Cause of Death of Bartley Crum
Bartley Crum was the attorney for some of the so-called "Hollywood Ten" who were subpoenaed to appear before the House Un-American Activities Committee in 1947. The FBI tapped Crum's phones, opened his mail, and shadowed him constantly. Labeled as subversive, he ended up losing most of his clients and, unable to cope with stress from the harassment, committed suicide in 1959 by washing down an entire bottle of Seconal with whisky.

## Cause of Death of Judy Garland
Judy Garland, of "The Wizard of Oz" fame, was found dead in her bathroom by her husband Mickey Deans on June 22, 1969. The stated exact cause of death by coroner Gavin Thursdon was accidental overdose of barbiturates; her blood contained the equivalent of 10 1.5-grain Seconal capsules.

## Role in Death of Jimi Hendrix
Secobarbital played a role in the September 18, 1970 death of legendary rock guitarist Jimi Hendrix, who purportedly took nine Secobarbital tablets after a night of drinking wine and was later found dead in his London apartment.  Hendrix' death was caused by asphyxiation, after Hendrix presumably vomited in his sleep as a result of the mixture of the excessive Secobarbital dose and alcohol.

# Use as a lethal injection
Secobarbital overdose was the most common method of implementing physician-assisted suicide (PAS) in Oregon until Eli Lilly and Company discontinued manufacturing it in May 2001, leading to a shortage of the drug. Since then, pentobarbital has dominated in Oregon PAS. Ranbaxy Laboratories Limited have experienced approval issues in their attempts to produce 100 mg secobarbital capsules, but there is no longer a shortage as of October 2006.
It is a component in the veterinary drug Somulose, used for euthanasia of horses and cattle.
