What causes opioid addiction, and why is it so tough to combat? - Mike Davis

Summary

Opioids: History and Effects

Opium from the poppy was used in ancient remedies and for its pleasurable effects. Morphine and codeine are opiates, compounds derived directly from opium. Opioids is the broader term for natural and synthetic drugs that act similarly, including heroin, hydrocodone, oxycodone, and fentanyl.

Opioids bind to receptors in the brain and body more strongly and for longer than natural endorphins. They reduce pain and can trigger dopamine release, producing pleasure or euphoria. They also suppress noradrenaline, which affects functions such as breathing, wakefulness, digestion, and blood pressure.

This can cause side effects such as constipation. At high doses, opioids can dangerously slow breathing or heart rate, leading to unconsciousness or death.

Dependence and Addiction

Repeated opioid use can lead to tolerance and physical dependence:

1. Opioid receptors may become less responsive or decrease in number. This is called tolerance.
2. A person may need larger doses to produce the same effects.
3. Opioids lower noradrenaline. To compensate, the body increases its sensitivity to it, adapting to the drug’s presence.
4. The body can become physically dependent on opioids to maintain this new balance.
5. If opioid use stops abruptly, noradrenaline rises while the body is still highly sensitive to it. Withdrawal can include muscle aches, stomach pain, fever, and vomiting, and can be severely debilitating.
6. Some people continue using opioids not to get high, but to avoid withdrawal.

Returning to opioids after a period without them is especially risky. A dose that once seemed standard may cause an overdose because tolerance has fallen.

How the Crisis Developed

The video says pharmaceutical companies aggressively marketed opioid painkillers in the 1980s and 1990s while downplaying addiction risk. Prescriptions and addiction cases rose. Although prescriptions have become more regulated, overdose and addiction remain serious problems.

The video describes a shift from many early cases involving middle-aged people who became dependent on prescribed painkillers to younger people who may start with prescription drugs and later turn to cheaper, more accessible heroin or illicit synthetic opioids.

Prevention and Treatment

Naloxone is presented as the best current defense against opioid overdose. It binds to opioid receptors without activating them, blocks other opioids, and can displace them from receptors to reverse an overdose.

Treatment often needs to address mental health conditions alongside opioid dependence. Programs may combine medication, health services, and psychotherapy. Inpatient and outpatient programs can be difficult to access: they may be expensive, have long waiting lists, or require detoxification and time away from work or housing.

Opioid maintenance programs aim to reduce opioid abuse while avoiding withdrawal. They combine medication and behavioral therapy, using drugs that bind to opioid receptors without the same psychoactive effects as commonly misused opioids. Methadone and buprenorphine are named as the primary maintenance medications.

The video notes an access barrier: doctors need a special waiver to prescribe methadone or buprenorphine, even though no specific training or certification is required to prescribe opioid painkillers. It also says buprenorphine can be scarce enough to have a growing black market.
