I am on subutex maintenance and this weekend binged on opiates (heroin and possibly fentanyl laced heroin) and crack. I know you are supposed to wait for a while before you take subutex after opiates, but my understanding is that you are supposed to wait until withdrawals to take subutex, but I suspect that may not be true after a weekend binge. My last use was a point or 2 10 hours ago. I just took some Xanax and my plan is to wait until I get up tomorrow to take the subutex, but am I safe to take it even sooner?
