Pharmacology of Opioids: Mechanisms, Risks, Withdrawal, and Treatment in Counseling

This episode offers an in-depth exploration of opioid pharmacology, detailing their mechanisms of action, the short-term and long-term impacts on the body and mind, and the significant risks associated with their use and abuse. It differentiates between natural, synthetic, and semi-synthetic opioids, classifying them as CNS depressants with unique analgesic properties that distinguish them from other depressants. A crucial aspect covered is the method of administration, emphasizing how routes like injection or snorting dramatically increase drug intensity and overdose potential compared to oral ingestion, a vital point for client education.

The discussion delves into the neurochemical intricacies of opioid action, explaining how they bind to the same receptors as the body's natural endogenous opioids but with far greater potency. The speaker elucidates how opioids reduce GABA, which subsequently boosts dopamine (the reward chemical) and norepinephrine (associated with energy and focus), and also increases serotonin levels. This complex neurochemical interplay accounts for the varied experiences users report, from euphoria and heightened energy to profound sedation. A critical distinction highlighted is the rapid development of tolerance (within 5-7 days) and its equally swift reversal, making relapse particularly dangerous as a previously tolerated dose can become lethal.

For mental health counselors, the episode provides practical insights and recommendations. It underscores the ethical imperative to educate clients about the risks of different administration methods, the rapid onset of tolerance, and the severe dangers of combining opioids with other CNS depressants like alcohol, benzodiazepines, or even antihistamines due to potentiation and synergism. While acknowledging the extreme discomfort of opioid withdrawal, the speaker notes it is generally not medically life-threatening if hydration is maintained, unlike withdrawal from alcohol or benzodiazepines. Practical advice includes offering palliative care during detox and recognizing the high prevalence of dual diagnoses, as many clients with opioid use disorder also struggle with co-occurring depression and anxiety, often engaging in self-medication.

The broader implications of the opioid crisis are also addressed, linking the increased difficulty in obtaining prescription opioids to a surge in demand for illicit substances like heroin and fentanyl. Fentanyl, being 30-50 times stronger than heroin, is identified as a major contributor to overdose fatalities. The episode reviews medication-assisted treatments (MAT) such as methadone (a full agonist) and buprenorphine/naloxone (Suboxone, a partial agonist with a ceiling effect), stressing that these are intended as temporary supports for skill development rather than indefinite maintenance. The speaker also raises ethical concerns about the controversial idea of using opioids for treatment-resistant depression, citing issues of tolerance, dose escalation, and the potential for abuse, especially in light of evolving government regulations on opioid prescriptions. The overarching message for practitioners is to be well-informed, intervene effectively, and help destigmatize legitimate pain management while actively working to prevent addiction.

"the method of administration greatly affects the intensity and duration of onset for various drugs not just opiates"

"opiates bind to the same receptors but are fifty to a thousand times stronger than endogenous opioids"

"tolerance to opiates... develops inside to seven days"

"if you take it for a while to make prescribed opiates for a while then the body quits producing endogenous opioids"

"medical complications arise primarily from adulterants meaning somebody put something in there like comet or you know something really nasty just to extend the amount of the drug they had or they put in something cheaper to produce like fentanyl"

"antihistamines and opiates have a enhancing effect so it's like one plus one equals five"

"withdrawal from opiates is miserable but technically unless the person gets dehydrated... the detox from opiates is not medically it's not as life-threatening as they detox from benzos or from alcohol"

"fentanyl is 30 to 50 times stronger than heroin and overdose rates are extremely high"

"my concern... is the fact that even people who are on opiates for pain control have to increase the dose of opiates they're on overtime because they become tolerant"

"once people try opiates if they have that AHA experience it becomes much more dangerous in terms of potentially enticing them to return to that drug for relaxation"
