4-FA (4-FLUOROAMPHETAMINE) is a substituted amphetamine that offers effects somewhere between those of amphetamine and MDMA. It’s been a member of the research chemical market since the late 2000s.
It has at times been a more popular research chemical because it does have a unique and potentially desirable effect profile.
Not enough is known about the drug to be sure about its safety level, particularly with chronic use.
4-FA (4-FLUOROAMPHETAMINE) elevates the mood, increases feelings of empathy and warmth, evokes a sense of openness and togetherness and may cause excessive talking. Furthermore, 4-FA enhances sensory perception, gives a body high and stimulates the lust to dance.
Like other amphetamines, 4-FA causes stiff jaws and bruxism (grinding of teeth) in some users and it suppresses the appetite. Compared with other research chemicals the hyperthermic effect seems to be less severe, though overheating is still a possible risk.
In general different amphetamines (MDMA, speed) combine together well, though some users reported 4-FA suppresses the euphoric effects of MDMA.
Some people combine 4-FA with methylone (MDMC), another research chemical that’s closely related to MDMA. Both positive and negative experiences have been reported, though presumably, this combination is quite harmful to the brain, as the neurotoxicity of both substances adds up.
Alcohol in combination with amphetamines taxes the liver and kidneys, causing dehydration. This might lead to overheating and increases the bad side-effects.
How did you start using?
A: I was injured on the job, and the doctor prescribed Vicodin to help ease the pain. I went down to the pharmacy and picked up my hydrocodone – the generic version of the drug. I was a little hesitant to take these pills at first. However, since I was in a lot of pain, I figured I better do what the doctor advised.
Q: How did you respond to the medication?
A: Well, it didn’t help cure my back problem, but it really relieved the pain. I found that I could go back to work, pick up my kids and do just about anything I used to do before I injured myself. I felt like a million bucks, all things considered.
Q: And were there any other reactions to?
A: Oh, yes. Almost from the first time I took the drug, I got a nice little buzz off of it. Nothing too radical, mind you. But, after taking the Vicodin, I was always in a good mood. I was cheerful and feeling like I could take on the world, you know?
Q: And then what happened?
