How does rohypnol affect the brain?

Rohypnol, a potent sedative, primarily affects the brain by enhancing the effects of the neurotransmitter gamma-aminobutyric acid (GABA). This leads to increased inhibition of neural activity, resulting in sedation, muscle relaxation, and amnesia. The drug can also impair cognitive functions and motor skills, making it dangerous, especially in combination with alcohol or other depressants. Its use is often associated with illicit activities due to its potential for misuse and the severe effects it can have on memory and judgment.
