Final answer:
The side effects of taking gamma-hydroxbutyric acid (GHB) can range from increased alertness and euphoria to seizures and hallucinations. High doses can even result in brain toxicity and death.
Step-by-step explanation:
The side effects of taking gamma-hydroxbutyric acid (GHB) can vary depending on the dosage. In low doses, GHB can result in increased alertness, mild euphoria, and decreased appetite. However, high doses of GHB can lead to agitation, paranoia, hallucinations, heightened sensitivity to physical stimuli, and even seizures. It is important to note that high doses of MDMA, which is chemically related to GHB, can cause brain toxicity and death.
