How long do its effects last?
Onset of effects
Duration of effects
The euphoria, anxiety suppression and pain relief effects appear to stem from the way in which opioids mimic endogenous endorphins. Endorphins are responsible for analgesia, causing sleepiness, and feelings of pleasure. They can be released in response to pain, strenuous exercise, orgasm, or excitement. This mimicking of natural endorphins results in the drug's effects. It acts primarily on μ-opioid receptors, with about six times lesser affinity to δ-opioid receptors .
Hydrocodone, a semisynthetic opiate agonist and hydrogenated ketone derivative, is similar to other phenanthrene derivatives, such as codeine. Used as an analgesic, hydrocodone is combined with acetaminophen, ibuprofen, or aspirin to treat pain. Used as an antitussive, hydrocodone is combined with phenylephrine, pseudoephedrine, phenylpropanolamine, guaifenesin, pyrilamine, pheniramine, or chlorpheniramine. Opiate agonists exert their principal pharmacologic effect at specific receptor binding sites in the CNS and other tissues. There are several subtypes of opiate receptors including the mu receptor (localised in pain modulating regions of the CNS), the kappa receptor (localised in the deep layers of the cerebral cortex), the delta receptor (localised in the limbic regions of the CNS), and the sigma receptor (thought to mediate the dysphoric and psychotomimetic effects of some opiate partial agonists). Agonist activity at the mu or kappa receptor can result in analgesia, miosis, and/or decreased body temperature. Agonist activity at the mu receptor can also result in suppression of opiate withdrawal, whereas antagonist activity can result in precipitation of withdrawal. Opiate agonists act at several sites within the CNS involving several systems of neurotransmitters to produce analgesia, but the precise mechanism of action has not been fully determined. Opiate agonists do not alter the threshold or responsiveness of afferent nerve endings to noxious stimuli nor the conduction of impulses along peripheral nerves. Instead, they alter the perception of pain at the spinal cord and higher levels in the CNS and the person's emotional response to pain .

Mechanism of action
Hydrocodone acts as a weak agonist at OP1, OP2, and OP3 opiate receptors within the CNS. Hydrocodone primarily affects OP3 receptors, which are coupled with G-protein receptors and function as modulators, both positive and negative, of synaptic transmission via G-proteins that activate effector proteins. Binding of the opiate stimulates the exchange of GTP for GDP on the G-protein complex. As the effector system is adenylate cyclase and cAMP located at the inner surface of the plasma membrane, opioids decrease intracellular cAMP by inhibiting adenylate cyclase. Subsequently, the release of nociceptive neurotransmitters such as substance P, GABA, dopamine, acetylcholine, and noradrenaline is inhibited. Opioids such as hydrocodone also inhibit the release of vasopressin, somatostatin, insulin, and glucagon. Opioids close N-type voltage-operated calcium channels (OP2-receptor agonist) and open calcium-dependent inwardly rectifying potassium channels (OP3 and OP1 receptor agonist). This results in hyperpolarization and reduced neuronal excitability .

- Ketamine - Both substances bring a risk of vomiting and unconsciousness. If the user falls unconscious while under the influence there is a severe risk of vomit aspiration if they are not placed in the recovery position.
- MXE - This combination can potentiate the effects of the opioid.
- DXM - CNS depression, difficult breathing, heart issues, hepatoxic, just very unsafe combination all around. Additionally if one takes dxm, their tolerance of opiates goes down slightly, thus causing additional synergistic effects.
- Cocaine - Stimulants increase respiration rate allowing a higher dose of opiates. If the stimulant wears off first then the opiate may overcome the patient and cause respiratory arrest.
- Alcohol - Both substances potentiate the ataxia and sedation caused by the other and can lead to unexpected loss of consciousness at high doses. Place affected patients in the recovery position to prevent vomit aspiration from excess. Memory blackouts are likely.
- GBL / GHB - The two substances potentiate each other strongly and unpredictably, very rapidly leading to unconsciousness. While unconscious, vomit aspiration is a risk if not placed in the recovery position.
- Tramadol - Concomitant use of tramadol increases the seizure risk in patients taking other opioids. These agents are often individually epileptogenic and may have additive effects on seizure threshold during coadministration. Central nervous system- and/or respiratory-depressant effects may be additively or synergistically present.
- Benzodiazepines - Central nervous system and/or respiratory-depressant effects may be additively or synergistically present. The two substances potentiate each other strongly and unpredictably, very rapidly leading to unconsciousness. While unconscious, vomit aspiration is a risk if not placed in the recovery position. Blackouts/memory loss likely .
- PCP - PCP can reduce opioid tolerance, increasing the risk of overdose.
- Nitrous oxide - Both substances potentiate the ataxia and sedation caused by the other and can lead to unexpected loss of consciousness at high doses. While unconscious, vomit aspiration is a risk if not placed in the recovery position. Memory blackouts are likely.
- Amphetamines - Stimulants increase respiration rate allowing a higher dose of opiates. If the stimulant wears off first then the opiate may overcome the patient and cause respiratory arrest.
- MAOIs - Coadministration of monoamine oxidase inhibitors (MAOIs) with certain opioids has been associated with rare reports of severe and fatal adverse reactions. There appear to be two types of interaction, an excitatory and a depressive one. Symptoms of the excitatory reaction may include agitation, headache, diaphoresis, hyperpyrexia, flushing, shivering, myoclonus, rigidity, tremor, diarrhoea, hypertension, tachycardia, seizures, and coma. Death has occurred in some cases .
- constant shivering,
- body aches,
- intense sweating,
- rapid or irregular heartbeat,

Withdrawal from long-term hydrocodone use can be very unpleasant. The opiate withdrawal syndrome is frequently described as having flu-like symptoms. Despite the potential for some profoundly uncomfortable moments, the opiate detox process is not typically life-threatening.
Any one of these symptoms may be enough to send a user back to the drug for relief, and that is why inpatient treatment centers are a safe, caring and effective place to deal with hydrocodone withdrawal.
Some treatment programmes administer medications to ease the patient's withdrawal. This form of medical assistance sometimes involves other potentially addictive substances, and is strictly controlled and monitored by addiction treatment professionals.
Treatment focused on the addiction will prove highly valuable moving forward, but another important part of treatment involves discovering why you became addicted and how you can live without the substance in the future.
Mental health treatment, like cognitive-behavioral therapy, can help those addicted to retrain their minds and teach them new ways to deal with pain and other circumstances that led to substance abuse .
Treatment for hydrocodone addiction is similar to heroin addiction treatment in that it utilises many of the same evidence based methods. Methadone, buprenorphine, and naltrexone are all medications that can be used to stabilise the patient and minimise their chance of relapse. Behavioural therapies can be helpful to change the way an individual thinks about their substance abuse as well as to teach them better coping skills for the future.
Any comorbid disorders associated with one's drug abuse should be assessed and treated in addition to their addiction, and depression is extremely common among hydrocodone addicts. Antidepressants can often be used as well as therapy models like cognitive-behavioral therapy that can treat both addiction and mood disorders at the same time. Depending on the severity of the individual's condition, inpatient care might be necessary, but many people receive proper and effective treatment in an outpatient programme .
According to the DEA, hydrocodone is the most commonly prescribed (and the most abused) opioid drug in the United States, and the National Institute on Drug Abuse (NIDA) reports that the US consumes nearly 100% of the world's supply of this drug . The following key statistics illustrate the extent of hydrocodone abuse -
- According to the National Survey on Drug Use and Health and Health (NSDUH), 4 million people over the age of 12 reported using hydrocodone for nonmedical purposes in 2013.
- Over 29,000 hydrocodone-related exposures and 36 deaths were reported in the U.S. in 2012, according to the American Association of Poison Control Centers.
- The Drug Abuse Warning Network (DAWN) estimated that there were more than 82,000 emergency room incidents in 2011 related to non-medical abuse of hydrocodone .
The number of prescriptions for hydrocodone written in the United States has increased dramatically in the last 25 years. This increase in prescriptions has, in turn, increased the rate of prescriptions diverted to the illicit market. The availability of hydrocodone on the black market has skyrocketed as a result .
Hydrocodone was first synthesised in Germany in 1920 by Carl Mannich and Helene Löwenheim. Hydrocodone is derived from codeine. As a semi-synthetic opioid, it is most often used orally as a narcotic analgesic and antitussive. Used mostly in combination with Acetaminophen (Vicodin) or Ibuprofen .
The first report, that hydrocodone produces euphoria and habituation symptoms, was published in 1923. The first report of hydrocodone dependence and addiction was published in 1961 .
