What are Quaaludes (methaqualone)? Quaaludes (methaqualone) are a synthetic, barbiturate-like, central nervous system depressant. Methaqualone is an anxiolytic and a sedative-hypnotic drug. Quaaludes were introduced as a safe barbiturate substitute, but they later showed that the possibility of addiction and withdrawal symptoms were similar to those of barbiturates.

Fetal Risk Summary

No reports linking the use of methaqualone with congenital defects have been located. One manufacturer was not aware of any adverse effects following 1st trimester use (R.R. Smith, personal communication, William H. Rorer, Inc., 1972). The autopsy of a 6-day-old infant found a congenital hypothalamic hamartoblastoma and multiple malformations (1). The baby had been exposed to methaqualone, marijuana, and cocaine early in gestation, but the correlation to any of these agents is unknown. Methaqualone is often used as an illicit abuse drug. Separating fetal effects from adulterants or other drugs is not possible. Because of the abuse potential, methaqualone is not recommended during pregnancy.

Questions and Answers

Can Methaqualone be made in a home lab,, or are the chemicals that are needed,, too difficult to obtain??, There are many articles naming the precursor chemicles, but it seems that there are not available in the U.S.

Not easy to make Quaaludes in a bath tub. A four ring aromatic compound like that takes some sythetic skills.

Yes the US cracked down on the precursor chemicals for most drugs many years ago. In fact now it is comon to hear about smuggled precursors being interdicted.

what are Amphetamines, barbiturates, benzodiazepines, methaqualone, opiates, and phencyclidine.?, Also can you tell me which ones are downers or uppers and if they are use in the medical profession today

Amphetamines are stimulants (eg. Dexedrine, Benzedrine)

Barbiturates are the old fashioned sleeping pills that have now been replaced with benzodiazepines, because too many people were dying from taking bariturates. They are very deadly. (eg. Amytal, Butalbital, Seconal, Veronal, Luminal)

Benzodiazepines are the new generation of sleep aids that have replaced the barbiturates. Unfortunately, they too are highly addictive and difficult to stop using. (Eg. Valium, Xanax, Klonopin)

Methaqualone was used as a sleep aid somewhere in between when Barbiturates were used and Benzos were invented. This was in the 60s. They were very popular and were called "Ludes" (eg. Quaalude, Mandrax)

Opiates are drugs developed from the opium poppy. They exert a morphine like action in the brain and reduce pain, whilst also causing euphoria. They can be natural (Morphine) or semi-synthetic (Codeine, Heroin, Nicomorphine) or fuly synthetic (Demerol, Fentanyl)

Phencyclidine is called a dissociative anaesthetic. It was used in the 70s but is now NOT used on humans due to unpredictable side effects and the fact the it's very neurotoxic. It's called PCP or Angel Dust.

All the above drugs are still used in medicine except methaqualone and PCP which are still used in research ONLY.
Uppers: Amphetamines
Downers: Barbs, Benzodiazepines, Methaqualone, Opiates

EDIT: Technically speaking PCP is neither an upper or a downer, although it can have both effects. Best way to describe it is "Dissociative" like Ketamine or DXM
Hallucinogenic/Deleriant: PCP, Methaqualone

Is Methaqualone made anywhere in the world??,

Since methaqualone is no longer legally produced, illicit manufacture either in India, or in South Africa itself or other African countries produces methaqualone for the South African market.

Is methaqualone (ludes) legal anywhere?, Is methaqualone (ludes) legal anywhere?

about the only place you can find it is south africa and its illegal there too

Methaqualone--Quaalude?, Were the original quaaludes(Roher and Lemon714) made from just pure methaqualone, or was some type of activating chemical added to create the euphoric effect? Not Mandrax, it has antihistimine.

Yes it seems so after reading this

Looking at the structure of methaqualone it seems and as the site quated to have a sedating effect the same as or close to barbiturates .... barbiturates cause a sedating effect or CNS depression by binding to the GABA type A or B receptor.

binds on the Allosteric site of the receptor ... causing an influx of Cl- ... which causes hyperpolarisation and decreases action potential .. hence CNS depression and the syptoms .

i think euphoria is brought by the drug rather than any additives added

Any idea about Methaqualone?, I was trying to find out if methaqualone (yeah, qualoeds) is still legal in any country, I know that in Argentina, is used as an anesthesic, the name there is metacualona, and is legal, but you have to be an anesthesiologist to get that.. Is only curiosity, i work as a bartender and i listen to the people that are 30 to 45 years old talk about that all the time, and I want to know if is legal somewhere. I dont use drugs at all, in fact, never tried nothing because i find everithing nasty( smoke, snore, etc), but I allways like to know more.. I live in Miami, pretty much the drug emporium... jaja

You can get it illegally, but not legally anywhere in the world. (Assuming you are not an anesthesiologist.)

but methaqualone without a prescription?, WHERE It's Quaalude

it was withdrew in the 1980's so nobody should have any.

how mandrax (methaqualone) is isolated, identified and determined?,

sorry, just have some infos

Methaqualone1 is a sedative drug.

It is similar in effect to barbiturates, a general CNS depressant. It was used in the 1960s and 1970s as an anxiolytic, for the treatment of insomnia, and as a sedative.

Usual effects include relaxation, euphoria, and drowsiness, also reducing heart rate and respiration. Larger doses can bring about depression, muscular miscoordination, and slurred speech.

An overdose can cause delirium, convulsions, hypertonia, hyperreflexia, vomiting, renal insufficiency, coma, and death through cardiac or respiratory arrest. It resembles barbiturate poisoning but with increased motor difficulties and a lower incidence of cardiac or respiratory depression. Toxicity is treated with diazepam and sometimes an anticonvulsant.

Methaqualone was discovered by the Indian researcher M. L. Gujiral in 1955 during an anti-malaria research program. It was marketed as a sleeping pill during the 1960s under a number of tradenames including Renoval and Melsed and in combination with an antihistamine as Mandrax. From 1965 it was sold on the U.S. market as Quaalude, Sopor and Parest; by 1972 it was the sixth most popular sedative in the US. The name Quaalude was apparently derived from the phrase 'quiet interlude' [citation needed] with an added 'aa' by the manufacturers in order to elicit a more positive public recognition, as was done with the drug Maalox. It was hoped that it was a 'safer' drug than barbiturates to use for sedation; however, it was found to have similar problems of tolerance and dependence.

Quaaludes became increasingly popular as a recreational drug during the 1960s. The drug was more tightly regulated in Britain under the Misuse of Drugs Act 1971 and in the US from 1973. With its addictive nature clear, it was withdrawn from many developed markets in the 1980s, being made a Schedule I drug in the US in 1984. Up until the fall of Nicolae Ceau┼čescu's regime in 1989, methaqualone (along with other sedatives) was used to pacify orphans in Romania's state-run orphanage system. Internationally, methaqualone is a Schedule II drug under the Convention on Psychotropic Substances. [1]

It is widely believed that the Church of Scientology was founded after a weekend-long Quaalude binge by its founders in the mid-1970's. In fact, one might theorize that part of the drug's placement on Schedule I was due to its role in the creation of this church. Despite the fact that 'ludes are almost impossible to obtain in the United States, Scientology is still around. Were it not for methaqualone, the Church of Scientology would not exist today.[citation needed]

Smoking methaqualone, either alone or as an adulterant added to various legal and illegal smoking mixtures, gained popularity in the United States during the mid 1970's. When smoked methaqualone gives the user an immediate trance-like euphoria that quickly wears off. Because the various binders and inert ingredients that were contained in the pill form were toxic when smoked, this practice was roundly decried by the medical community as a serious health risk. Smoking methaqualone quickly leads to emphysema and other chronic lung disorders.

Smoking marijuana laced with methaqualone has become a major problem in South Africa, rivalling crack cocaine as the most abused hard drug. Its low price (R30.00 average against R150.00 for crack) means it is the preferred hard drug of the large low-income section of society.
