Substance Use Disorder SUD: Symptoms & Treatment

Ott 18 2021

difference between heroin and cocaine

An opiate (narcotic) drug processed from morphine and extracted from certain poppy plants. Heroin comes in a white or brownish powder, or a black sticky substance known as “black tar heroin.” Often “cut” with other drugs or substances such as sugar or powdered milk. User is unaware how much actual heroin is being used, creating likelihood of overdose.

“The mice just couldn’t learn where they received their morphine reward,” Monje said. Research in neuroplasticity has mostly focused on changes that occur at synapses — where neurons meet and communicate with each other. In adaptive myelination, more active brain circuits gain more myelin — the fatty insulation that allows electrical signals to travel faster and more efficiently through nerve fibers. Learning to juggle or practicing the piano, for example, gradually increases myelination in the brain circuits involved, optimizing for these abilities. The complications of substance use disorder are broad and may depend on the type of substance use.

Substance use disorders

In addition, excessive use of either drug can lead to a potentially fatal overdose. (It’s worth noting that even habitual cocaine users can experience overdoses when consuming smaller amounts of the drug, as well.) It’s important to seek treatment for cocaine use or treatment for heroine use before suffering fatal or long-term consequences. Heroin addiction treatment often includes medication-assisted treatment (MAT), which combines medications like methadone or buprenorphine ecstasy mdma or molly with counseling and behavioral therapies. MAT helps to reduce withdrawal symptoms, prevent relapse, and stabilize individuals in recovery. Additionally, support groups and aftercare programs play a crucial role in providing ongoing support and preventing relapse for both cocaine and heroin addiction. Both cocaine and heroin have profound effects on the body, but they differ in terms of the specific physiological and psychological responses they elicit.

Common Neurological Risks of Drug Abuse

Addiction was historically viewed as a disease of “weak personality” and was not systematically addressed by the scientific and medical communities until the latter half of the 20th century. Pioneering studies in the 1960s and 1970s led to the development of methadone, the first (and still effective and widely used) treatment for the long-term management of addictions to heroin and other opiates (1–3). During the 1980s, efforts coalesced around the investigation and development of pharmacological treatments for other drugs of abuse, including alcohol and cocaine, though there are still no approved medications for the treatment of cocaine addiction.

SUD also recognizes a spectrum of problematic substance use, not just physiologic addiction. A person can have more than one substance use disorder at a time, such as alcohol use disorder and cocaine use disorder. Fentanyl and other synthetic drugs are also increasingly showing up in non-opioid drugs, including coke and molly. Even a small amount of fentanyl contamination can greatly increase your risk of experiencing a potentially fatal overdose. As the drugs wear off, all that excess serotonin and dopamine gets reabsorbed or broken down.

10. Management of Acute Intoxications and Cocaine Use Disorder

  1. DAT, dopamine transporter; NAT, noradrenaline transporter; SERT, serotonin transporter.
  2. Substance use disorder (SUD) is a complex condition that involves a problematic pattern of substance use.
  3. There were significant increases in SOD activity, ROS, protein carbonylation and lipid peroxidation, cleaved caspase-3 expression and intramitochondrial calcium, accompanied by a significant decrease in GPx.
  4. Plastic trays covered with pine wood shavings were placed under the cage floors.
  5. The choice of the drug to combine with cocaine is often based on the desire to counteract the stimulant (‘upper’) effects of cocaine, so another drug to ‘mellow down’ (a ‘downer’) is frequently selected.

To overcome these limitations, novel methodologies should be developed to elucidate the interoceptive and exteroceptive components of drug-setting interactions and dissect the exact role of relevant brain networks. Most pharmacotherapies currently approved for the treatment of addictive disorders target MOP-r. The full MOP-r agonist methadone is approved in the chronic maintenance treatment of addiction to heroin or prescription opioids, as is the MOP-r partial agonist buprenorphine. Monthly depot formulation (e.g., for the treatment of alcoholism, and more recently for the prevention of relapse to opioid dependence following detoxification), has powerful MOP-r antagonist effects. Of interest, both buprenorphine and naltrexone also have affinity at KOP-r, and buprenorphine is also a partial agonist at orphanin FQ/nociceptin receptors (N/OFQ-r), with relatively low potency. Activation in the dopaminergic mesocortico/mesolimbic and nigrostriatal systems, either directly in the case of cocaine or indirectly for heroin/prescription opioids or alcohol, appears to be a common neurobiological consequence of exposure to drugs of abuse (5–7).

Consider seeing a mental health professional if you’re having issues managing your stress. For an adult, a divorce, loss of a job or death of a loved one may increase the risk of substance use. For a how long does marijuana stay in your system teenager, moving, family divorce or changing schools can increase their risk. A provider will also ask about your mental health history, as it’s common to have an SUD and a mental health condition.

Adulterants and contaminants are often present in cocaine samples, as indicated by analysis of a pool of samples acquired in the street that averaged 40%. Many of these additives are often included to increase the perceived volume (e.g., talc, sugar or corn starch) or purity of cocaine (e.g., lidocaine, benzocaine, and procaine; caffeine, ephedrine) and may modulate cocaine’s biological effects, including toxicity [24]. In addition to these substances, polydrug use with both licit and illicit drugs is a common practice among cocaine users [2,145,146,147,148]. Polydrug use constitutes a risk for users for a myriad of reasons, including the potentiation of noxious effects of one drug by the other(s) due to the formation of new (and perhaps more toxic) metabolites and/or the competitive inhibition of metabolizing systems. The choice of the drug to combine with cocaine is often based on the desire to counteract the stimulant (‘upper’) effects of cocaine, so another drug to ‘mellow down’ (a ‘downer’) is frequently selected. Examples of these drugs are alcohol, benzodiazepines (e.g., lorazepam and diazepam), cannabis and opioids (e.g., heroin) [149].

Carriers of the 118G allele show an elevated sensitivity to pain and reduced analgesic response to opioids. Homozygotes for the 118G allele requested higher doses of oral morphine in treatment for cancer pain. Results of several studies suggest that the effect of the 118G allele may vary among different opioids, different routes of drug administration, or different pain etiologies, as recently reviewed (107).

Another minor metabolic reaction is the N-demethylation of cocaine to norcocaine (NCOC). In the presence of ethanol (EtOH), cocaine will undergo transesterification and form cocaethylene (CE). Coca leaves have been traditionally used by the indigenous Andean populations and were/are consumed mostly by chewing; coca leaves as a part of religious occasions and other celebrations by the Inca, as well as employed for medicinal purposes [22]. It was from the coca leaves that Albert Niemann first isolated cocaine in 1859–1860 [21,24]. The intravenous double-lumen catheters consisted of two 10.5 cm of silicone tubing (0.37-mm inner diameter, 0.94-mm outer diameter) sheathed, at 3.4 cm from its proximal end, by a 5-mm length of heat-shrink tubing.

While these substances are very different from each other, they all strongly activate the reward center of your brain and produce feelings of pleasure. This can create two very distinct experiences, but both have the potential to cause serious health issues. For example, levamisole — a veterinary deworming medication — is often found in cocaine. It can cause your bone marrow to stop making white blood cells called granulocytes, leaving you vulnerable to infections. Because of its effect on serotonin levels, MDMA may cause something called serotonin syndrome — a condition that results from too much serotonin in the body — when mixed with other substances that increase serotonin. It not only impacts your heart’s internal rhythm that keeps it beating, but also tightens the small blood vessels that feed the muscle.

Another significant difference between cocaine and heroin lies in the way they are typically administered. Cocaine is most commonly snorted as a powder, although it can also be dissolved and injected intravenously. The powder form is often mixed with other substances, such as talcum powder or baking soda, to increase profits for dealers. Injection provides the fastest and most intense effects, while smoking and snorting result in a slower onset of action. One of the brain areas still maturing during adolescence is the prefrontal cortex—the part of the brain that allows people to assess situations, make sound decisions, and keep emotions and desires under control. The fact that this critical part of a teen’s brain is still a work in progress puts them at increased risk for trying drugs or continuing to take them.

These gene variants may functionsynergistically with genetic polymorphisms involved in common comorbid conditions, such asanxiety or depression, and stress responsivity. Addictions can also be comorbid with majorinfectious disorders, such as HIV/AIDS (4). are common toads poisonous to humans The KOP-r/dynorphin system has emerged as a potential therapeutic target for both cocaine and heroin/prescription opioid addiction (see also below). Centrally active KOP-r high-efficacy agonists are generally psychotomimetic with aversive properties.

According to the2011 Monitoring the Future report, 1.2% of high school students in the USAreported lifetime use of heroin (43). Approximately 13%of high school seniors also reported nonmedical use of “other narcotic drugs,”such as the prescription opioids oxycodone and hydrocodone (44). Addiction is a chronic disease characterized by drug seeking and use that is compulsive, or difficult to control, despite harmful consequences. The initial decision to take drugs is voluntary for most people, but repeated drug use can lead to brain changes that challenge an addicted person’s self-control and interfere with their ability to resist intense urges to take drugs. These brain changes can be persistent, which is why drug addiction is considered a “relapsing” disease—people in recovery from drug use disorders are at increased risk for returning to drug use even after years of not taking the drug.

Of interest, naltrexone was effective in reducing use of amphetamine (anotherpsychostimulant compound acting through the dopamine transporter) in patients withoutcooccurring alcoholism (36). A form of long-term depression (LTD) that is observed in dopaminergic neurons in the ventral tegmental area and that reduces synaptic efficacy between presynaptic GABAergic neurons and postsynaptic dopaminergic neurons. A hypothetical motivational process that is inferred from findings of time-dependent increases in cue-induced drug seeking after withdrawal from drug self-administration in rats. Heroin is an opioid drug made from morphine, a natural substance taken from the seed pod of the various opium poppy plants grown in Southeast and Southwest Asia, Mexico, and Colombia. Heroin can be a white or brown powder, or a black sticky substance known as black tar heroin. It’s common for a person to relapse, but relapse doesn’t mean that treatment doesn’t work.

While the stimulation of α1-adrenergic receptors is related to contraction of bronchial capillaries, the activation of β2-adrenergic receptors induces bronchial muscle dilation. Of note, non-cardiogenic pulmonary oedema may occur due to damage of the endothelium of pulmonary vessels, which will also increase their permeability [83]. The vasoconstrictive properties of cocaine also affect the respiratory system, particularly at the nasal level for intranasal administration.

Table 1 summarizes the socio-demographic characteristics of the sample and basic information about drug use. The majority of the participants (86.79%) had a fixed residence at the time of their enrolment in the study. However, it is important to point out that the information concerning the setting of drug use referred to periods in which the participants had a fixed residence. Increased CRF activity in the central nucleus of the amygdala (CeA) underlies the anxiogenic and stress-like consequences of withdrawal common to many drugs of abuse (68, 70). CRF-R1 antagonists attenuate stress-induced reinstatement of cocaine or heroin seeking in rats (72). Administration of CRF to cocaine-addicted patients induced stress responses and subsequent cocaine craving (64).
