GHB is used as a recreational substance for its alcohol-like effects. While a common recreational dose is between 1.5 - 2.5 grams, a dose between 2.5 grams and 5 grams will likely result in falling asleep within 5 - 15 minutes, and a dose of 5 - 10 grams can result in convulsions, unconsciousness (a coma-like state) and vomiting. Doses above 10 grams are associated with a risk of death.<ref name="ErowidGHBVault">{{Citation | title=Erowid GHB Vault : Dosage | url=https://www.erowid.org/chemicals/ghb/ghb_dose.shtml}}</ref> Do not confuse grams with milliliters. If consuming GHB that has already been premixed into a liquid form, additional caution is required as there is no way to know for sure the concentration of the solution (e.g. how many grams of GHB is in each mL of solution). As such, users are advised to start with a low dose and work their way up slowly by increasing the dose in small increments. However, an appropriate interval between dosing is essential to avoid accidental overdose. | GHB is used as a recreational substance for its alcohol-like effects.

GHB, along with [[GBL]], has acquired a reputation as a "date rape drug," in which it is purportedly secretly placed into alcoholic drinks.{{citation needed}} There is very limited evidence to suggest that this actually happens but care should always be taken when accepting drinks from strangers. | GHB, along with [[GBL]], has acquired a reputation as a "date rape drug," in which it is purportedly secretly placed into alcoholic drinks.{{citation needed}} There is very limited evidence to suggest that this actually happens but care should always be taken when accepting drinks from strangers. | ||

Accidental ingestions of GHB have also occurred due to inadequate storage methods. If GHB is put into a clear liquid, glass, or bottle, it can be easily mistaken for water. It is recommended to clearly label your GHB in writing and dye the liquid with blue food coloring so it no longer resembles a drinkable beverage. It is also recommended to store your GHB in a container that no one would drink out of. | Accidental ingestions of GHB have also occurred due to inadequate storage methods.

GHB is also corrosive it is recommend it to dilute it with a non-alcoholic liquid in the ratio of atleast 1:100ml if not done this can result in burns in the intestine as well as the mouth.[https://sidekicks.berlin/en/ghb-gbl/#beratung] | |||

A 2022 review<ref>Amsterdam JV, Brunt TM, Pereira FR, Crunelle CL, Brink WVD. [https://web.archive.org/web/20230313103920/https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9878963/ Cognitive Impairment Following Clinical or Recreational Use of Gammahydroxybutyric Acid (GHB): A Systematic Review.] Curr Neuropharmacol. 2022;20(4):809-819.</ref> compared 43 studies on GHB-induced cognitive impairment in humans and animals. The analysis suggests that moderate or clinical use may result in acute cognitive impairment. Working memory, short-term memory, and impaired performance on cognitive tasks were impaired after doses as low as 10mg/kg, but these effects appear to be temporary. Conversely, one study found that a dose of 20mg/kg improved social and non-social cognition, but did not affect base cognitive functions, such as visual or verbal memory recall. However, chronic heavy use of GHB, especially if accompanied by GHB-induced comas appear to cause long-term cognitive impairment and are likely neurotoxic. | |||

One study found that repeated administration of GHB to rats for 15 days drastically reduced the number of neurons and non-neuronal cells within the hippocampus and in the prefrontal cortex. With doses of 10 mg/kg of GHB, they were decreased by 61% in the hippocampus region and 32% in the prefrontal cortex, and with 100 mg/kg, they were decreased by 38% and 9%, respectively. This paper demonstrates contradicting effects on neuronal loss, with lower doses (10 mg/kg) producing the most neurotoxicity, and higher doses (100 mg/kg) producing less. | One study found that repeated administration of GHB to rats for 15 days drastically reduced the number of neurons and non-neuronal cells within the hippocampus and in the prefrontal cortex.
