I suppose that can happen; I didn't know anybody who needed it then.
Also opiates like heroin do NOT cause dangerous withdrawal symptoms.
Didn't know that either. It must be extremely unpleasant to want a fix, I don't know. But you seem to know whereof you speak.
Opiate addicts are miserable in withdrawal. Anxious, sweaty, nausea, vomiting, diarrhea, cramps. But that’s about it. Alcohol and benzos, much worse, tachycardia, hypertension, hallucinations, seizures.
