if anything..all those things you asked about..well it does the complete opposite..

and while it CAN be slightly psychologically addicting...it doesnt allow you to stay addicted for more than about a year...seriously...if you are smoking it a lot for a year..like..all the time...you will want to stop at some point because you have drifted so far from this reality that you cant tell whats real anymore...and then the spice starts kicking you ass...
