People's body chemistry varies so. My friend will take loritabs if he can get them, and he says they give him energy? I played with cke in the '80s and never felt any physical need for it. DID NOT try crack when offered, so am not sure if the instant addiction is justified. The opioid problem in my part of the U.S. is that when the person can no longer access the drug legally, they turn to street heroin with it's problems of purity and all. Mike
