So I just pissed in a cup for probation around 9am and I last used heroin the night before around 8pm. I'm thinking about getting a prescription of promethazine with codeine so I can tell the probation officer it was the codeine that caused the dirty test.. since heroin is broken down to codeine after using. This should work right? As long as there was enough hours so a 6-acetyl-morphine does NOT show up, correct? Quoted from erowid.com
That could work but the problem would be if he checks the date on the script. If you got it after the drug test it might raise his suspensions and give him cause for a more thorough test. Hell, he might do that anyway.
I've pissed dirty without doing any opes for weeks, but I think I would remember doing some opes... I give up on those piss tests. I just show up and do it. If it's dirty, I don't really care since I usually didn't take any fucking opes and it's not like the doctors gonna go "OH OKAY!" and believe me.
