BENZODIAZEPINES (BZO)
common with amphetamine drugs, a capacity to increase blood pressure and heart rate. MDMA does Benzodiazepines are medications that are frequently prescribed for the symptomatic treatment of anxiety produce some perceptual changes in the form of increased sensitivity to light, difficulty in focusing, and blurred vision in some users. Its mechanism of action is thought to be via release of the neurotransmitter with Integrated E-Z Split Key™ Cup
and sleep disorders. They produce their effects via specific receptors involving a neurochemical called gamma aminobutyric acid (GABA). Because they are safer and more effective, Benzodiazepines have serotonin. MDMA may also release dopamine, although the general opinion is that this is a secondary replaced barbiturates in the treatment of both anxiety and insomnia. Benzodiazepines are also used as effect of the drug (Nichols and Oberlender, 1990). The most pervasive effect of MDMA, occurring in Instruction Sheet for testing of any combination of the following drugs:
