Scientific Name: (RS)-1-(4-Fluorophenyl)propan-2-amine
Effects: 4-Fluoroamphetamine has characteristics of both classic stimulants and empathogens like MDMA. Increased energy and alertness combined with euphoria, empathy and a desire to socialize are all common effects. One dose lasts between 5-8 hours on average, with effects taking hold within 45 minutes of ingestion.
Health Risks: Increased heart rate/blood pressure, dehydration and hyperthermia. Combining 4-FA with other stimulants like caffeine may increase these risks. For some users, 4-FA can lead to habitual abuse or dependence.
