#4-fluoroamphetamine

4-Fluoroamphetamine (4-FA) was particularly popular in the Netherlands, although it certainly gained traction elsewhere. Its effects are frequently pitched as being somewhere between MDMA and amphetamine, although I felt that it was far closer to the former than the latter. Be aware that there are numerous warnings of neurotoxicity and cardiovascular toxicity related to this drug, so caution is essential should you choose to use it.
