3 Phases of Cocaine Withdrawal: Roadmap to Recovery

Some effects of cocaine are almost instantaneous and typically last from a few minutes to 1 hour. After medical detox is complete, patients will be screened for entry into substance use disorder treatment. Treatment plans may continue in an inpatient (in the facility) or outpatient (live at home and commute to the facility) manner. Those who are ready for continued care can be admitted into a program at this time. An individual will have more time to focus on their recovery and be better equipped to maintain a healthy diet once they leave. The safest course of action for anyone working through the cocaine withdrawal process is to enlist the help of rehab specialists and participate in medical detox.

What are the effects of cocaine on the brain?

1. Unfortunately however, PET in human users is fairly invasive (requiring that addicts are given a dose of radiation and an arterial or venous line), expensive, and only available at research sites with rapid access to the radioligands.
2. For this FDG-PET study we enrolled 23 former cocaine users that were currently active participants in community-based outpatient and inpatient treatment programs, as well as 14 age-matched controls with no history of psychiatric illness or substance dependence.
3. However, cocaine causes intense cravings during withdrawal, which is one of many people’s main barriers to long-term recovery.
4. Here, recovery was found in only 60% of the monkeys within 3 months, whereas in the other 40% there was no evidence of recovery even after as long as a year after the cessation of cocaine use.
5. They investigated gray matter tissue density and white matter integrity among 50 sibling pairs (one cocaine dependent, one with no history of drug dependence), and 50 unrelated healthy controls.
6. It may not sound glamorous, but the first steps of recovery are simply developing healthy habits.

For this FDG-PET study we enrolled 23 former cocaine users that were currently active participants in community-based outpatient and inpatient treatment programs, as well as 14 age-matched controls with no history of psychiatric illness or substance dependence. The former cocaine users in this study had been abstinent from cocaine for up to 14 months. For preliminary analysis these 23 individuals were divided into groups of short term (1–5 weeks), middle term (1–5 months), and long term (10–14 months) abstinence, similar to the groups reported by Connolly et al (2012). Preliminary analysis of these data demonstrates that, consistent with the original PET studies in this area, short term abstainers have lower neural activity in both the frontal cortex and subcortical areas relative to the matched controls (Figure 1). The functional activity in the subcortical areas, however, did not vary as a function of length of abstinence. While these data are preliminary, cross-sectional, and from a limited sample, the results complement Connolly et al. (2012) and suggest that long-term abstinence from cocaine in humans may be more related to neural activity in the frontal cortex rather than the subcortical areas.

Investigating glutamate and GABA concentrations in human cocaine users however, is still in its infancy. Future research in this area holds tremendous potential for translating many of the basic science results of altered glutamate and GABA activity to new, potentially patient-tailored treatment options for human cocaine users. This elevated cortical integrity in brain regions involved in self-control may enable them to maintain abstinence for a longer time. This ‘survivor’ effect may also explain the elevated levels of frontal glucose metabolism that have been observed in these long term abstainers (Connolly et al., 2012). When considering the relative role of the frontal cortex versus subcortical areas on the maintenance of abstinence, it is important to acknowledge that nearly all behaviors in foods that contain alcohol the human repertoire are the result of complex interactions among neural systems which span multiple brain regions.

Long-term effects

Following this, you may enter an extended withdrawal phase, which can last for days or even weeks as cocaine remains in your system. For some individuals, certain symptoms, especially cravings or mood disturbances, can persist for a significant amount of time. Cocaine withdrawal, or withdrawal from any powerful drug, happens because of the way the drug interacts with the brain. Cocaine causes you to experience intense euphoria, due to the neurotransmitter, dopamine, (which is also known as the ‘happy chemical’) being sent to your brain. This initial high will usually last around 1-2 hours (although this will be shorter if you’ve taken crack cocaine).

While it has been shown to play a role in various forms of plasticity (Black, 1999; Bramham and Messaoudi, 2005), BDNF is also involved in the survival of dopamine neurons (Hyman et al., 1991). BDNF knockout mice have reduced locomotor responses to cocaine and diminished cocaine-induced conditioned place preference, compared to wild-type littermates (Hall et al., 2003). Subsequently it was shown that infusions of BDNF into the medial prefrontal cortex attenuate the reinstatement of cocaine-seeking (Berglind et al., 2007) and prevent cocaine-induced alterations in nucleus accumbens glutamate levels (Berglind et al., 2009).

Cocaine Withdrawal Timeline & Factors

(Graph inset) The time courses of cocaine-induced buildup of ΔFosB and cocaine-related structural changes (dendrite sprouting) suggest that these neurobiological effects may underlie some of the drug’s short-term, medium-term, and long-term behavioral effects. Dopamine originates in a set of brain cells, called dopaminergic (dopamine-making) cells, that manufacture dopamine molecules and launch them into their surroundings. Some of the free-floating dopamine molecules latch onto receptor proteins on neighboring (receiving) cells.

Furthermore, it is possible that lower D2 receptor concentrations may have predated drug use. In animal models where greater control over environmental and pharmacological variables can be exercised, Nader and colleagues have reported that D2 receptor availability following limited (less than a month) cocaine how to identify liberty caps exposure in nonhuman primates, recovered to control levels after only 1–3 weeks. However, this was not the case when longer periods (12 months) of exposure to cocaine self-administration were investigated. Here, recovery was found in only 60% of the monkeys within 3 months, whereas in the other 40% there was no evidence of recovery even after as long as a year after the cessation of cocaine use.

Recovering from Cocaine: Insights from Clinical and Preclinical Investigations

Short-term cocaine use can increase the risk of stroke, seizures, headaches, and coma. Symptoms dissipate completely after 10 weeks, but a person may experience intermittent cravings based on external cues. During this time, a person experiences mood symptoms, cravings, irritability, trouble sleeping and intense cravings.

These data emphasize the significance of the exposure period prior to the discontinuation of drug use. It is likely that because of the relatively short periods of exposure used in many studies using animal models, the intensity and duration of many neuroadaptations may be underestimated. Cocaine’s primary mechanism of action in the brain involves binding to the dopamine transporter which is highly concentrated in the basal ganglia (or striatum). Dopamine disruption in the striatum has been robustly studied in animal models of cocaine use and in several human imaging studies. Additionally however, many highly-cited human neuroimaging studies have revealed significantly lower rates of functional activity in the frontal cortex of cocaine users relative to non-drug using controls. This ‘hypofrontality’ was first documented in PET imaging studies which measured baseline glucose metabolism throughout the brain of cocaine users (Goldstein et al., 2004; Goldstein and Volkow, 2002; Volkow et al., 1991a; Volkow how to tell if weeds laced et al., 1992; Volkow et al., 2005).
