@Solace,
Just a point since i am a bit of a druggie!
It is a common misconception that dopamine is the feel good chemical.
It is most definatly not a feel good chemical.
It is the intensity chemical.
I used to do a drug called GHB and that lowered your dopamine and made you feel great. Then when it wore off you got a dopamine rebound whereby your dopamine would rocket up.
It did not make you feel good. It just made you feel over stimulated/wired.
Its like with high doapmine the voltage in your brain is turned up.
So the high dopamine with cocaine simply gives you a feeling of everything being intense. It is in fact the endorphins that give you the euphoria.
Its the same with serotonin. Every says that it is the HAPPY drugalso because of mdma/exctacy.
Again it is not. Serotonin is the depth chemical.
When serotonin is higher things seem deeper or richer.
Again it is the endorphins that mdma/exctacy produce that give the euphoria.
So to sum up dopamine is the intensity chemical, serotonin is the depth chemical and endorphins are the euphoria chemical.
The reason people get it wrong is because the dumb scientists who come out with all this crap have never taken a drug in thier life so they dont know what they are talking about.
