SOMEWHERE BETWEEN MDMA AND SPEED During the legal high years 4-Fluoroamphetamine (4-FA) was particularly popular in the Netherlands, although it certainly gained traction elsewhere too.
Its effects are frequently pitched as being somewhere between MDMA and amphetamine, although I felt that it was closer to the former than the latter, at least during the early stages. Later on, this balance seemed to change, making the overall ride somewhat variable.
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. Certainly, if you have any cardio-related issues, don't do it.
