I don't know the name of the drug that was like herion but like you said, any psychotropic drug can lead to havoc..just look at the SSRI's now in the news that they say can lead to suicide in teens.....I have reports and such on this and books that talk about his 5 years ago, but the drug companies hold all this stuff back.....I'm not as familiar with opiates......and there is a diffence between being an addict and physically dependent....I was not an addict cause it didn't make me high and there was no psychosocial behavior around the drug......i took it cause the doctor said I should.....I learned my lesson from that and he was dead wrong.........your body rejected them cause some people have paradoxical effects or they can become toxic which is different than "tolerance"
IMHO, these things should be prescribed for only a week before a follow-up appointment.
In my case, if I ever get into a serious injury situation, it will take a dilaudid injection to kill the pain.
Oxycodone is the cancer pain-management drug I was talking about.
