throughout the past 4 days i took a total of 8mg of subutex, with the last dose being about an hour ago which was not even 1mg. what would happen if in a few hours i blew some heroin? anything?
I predict the H will have no effect and will be wasted. Bupe's binding affinity is higher by many orders of magnitude. Even though you took a <1mg dose, it's enough to blockade your receptors. I'd wait at least a day so as not to waste any dope.
