GHB

GHB (Gamma-Hydroxybutyric Acid) is a CNS depressant used as intoxicant. It is a naturally occurring substance found in the human central nervous system, as well as in wine, beef, small citrus fruits, and in small amounts in almost all animals. GHB has been used in a medical setting as a general anaesthetic, to treat conditions such as insomnia, clinical depression, narcolepsy, and alcohol withdrawal, and to improve athletic performance.

History

GHB was synthesized and introduced into medicine in 1960 and in 1963 discovered as a naturally occurring chemical in the human brain.

Dosage

GBL dose: 1ml GBL is equal to 1.6g GHB

• Enhanced sensuality

Neutral

• Dizziness

Negative

• Nausea
• Restlessness
• Unconsciousness
• Amnesia

After effects

• Hangover (usually only occurs from high doses)
• #Dopamine Rebound

Harm Reduction

• The dosage curve of GHB is very steep, recreational doses being very close to doses which will cause a period of unrousable sleep, which are again relatively close to doses which may cause coma or death through respiratory depression.
• The only way to know the concentration of liquid GHB is to know and trust information provided by the source. Users should be extremely careful about GHB dosages as even small overdoses can result in temporarily unrousable sleep.
• Avoid driving and operating heavy machinery
• Don't mix it with alcohol, or other depressants
• 2-3 uses a week should be the maximum
• High addiction potential

Chemistry and Pharmacology

GHB has at least two distinct binding sites in the central nervous system. GHB is an agonist at the newly characterized GHB receptor, which is excitatory, and it is a weak agonist at the GABA-B receptor, which is inhibitory. GHB is a naturally occurring substance that acts in a similar fashion to some neurotransmitters in the mammalian brain. GHB is probably synthesized from GABA in GABAergic neurons, and released when the neurons fire.

If taken orally, GABA itself does not effectively cross the blood-brain-barrier.

Dopamine Rebound

GHB will reduce dopamine levels in high amounts, but increase dopamine levels in the brain in low amounts. This leads to what is known as dopamine rebound among users. Users can experience strong wakefullness about 4 hours after the last dose was consumed. This is often strong enough to wake the user up from sleep, and may be accompanied by a strong redose compulsion. The longer and higher the dose of GHB used, the more pronounced the effect may become.

Production

Production of GHB consists simply of mixing "lactone" (short for gamma butyrlactone) and lye (sodium hydroxide) in the proper amounts. It can also be converted from GBL.

Legal status

GHB is illegal in most parts of the world, GBL is legal in parts of Europe.
