A person gets "high" from opiates/opiods to do agonist activity primarily at the mu recp. If a person has no tolerance I.e. Non dependent taking a full or partial agonist will stimulate their recps past their baseline and they will notice a increase in mu activity. They are high. Regardless of affinities, kinetics, low, medium efficacys, partial, full agonism this person percieves a increase of mu stimulation and because high.
Now, if this person has increased their baseline(tolerance) with everyday usage of full agonists and they take a partial agonist that has a higher affinity for the mu recp also having a lower efficacy being a partial agonist this person will perceive a net decrease in mu stimulation and will go below their self imposed baseline and this will be felt as perc withdrawals. Because he/she is dependent on full agonist stimulation taking bupe ANTangonizes the full agonist and replaces itself on the mu rec being a partial agonist there is a net decrease in stimulation.
