MEAI hydrochloride is primarily used in research settings to study its effects on the central nervous system, particularly its potential to reduce alcohol consumption. It has been investigated for its ability to act as a substitute for alcohol, providing a similar euphoric effect without the associated harmful consequences. This makes it a candidate for therapeutic applications in treating alcohol dependency or addiction. Additionally, its properties are being explored for use in behavioral studies to understand its impact on mood and cognitive functions. Researchers are also examining its potential as a safer alternative in recreational contexts, where it may offer a controlled way to achieve desired psychological effects.
