I'll make a small confession... when I was going through suboxone detox, sometime in the middle of my taper I tried to snort my dose. I was just yearning for some kind of a buzz but didn't want to relapse. I almost posted a thread about this stupidity here but I didn't want to give anybody any ideas.
My conclusion: A total of waste of time. I don't think it effected me quicker, nor stronger.
So from drug addict to another, my advice is don't do it. Not because it's wrong, not because it represents a failure in your attitude towards quitting, but just because it doesn't effin' work!
