So theoretically if I have 30 mg of methadone, which does absolutely nothing to me except for keep the withdrawals away, and I want to get high with some known quality opium, and plenty of it, can I keep the methadone dose? I know that methadone has a much higher affinity for the receptors responsible for the high, but since I assume there are plenty more of those receptors that arent being triggered by the 30mg of methadone, would I get better results if I maintain the methadone at a low dose and add the opium? I realize this isnt exactly harm reduction stuff here, but lets just assume I am in no danger of overdose. Or, will the methadone, even in its low quantity, block out the morphine, thebaine, etc?
