Little evidence has examined the therapeutic effects of methylphenidate (MPH) and Matrix Model treatment on addiction severity, craving, relapse and mental health in people who use methamphetamine (PWUM). This study was conducted to determine the effects of MPH, Matrix Model treatment, and Matrix-MPH on addiction severity, craving, relapse and mental health in PWUM.

Purpose The purpose of this paper is to explore and describe first-person experiences of relational recovery in co-occurring mental health and substance use conditions. Design/methodology/approach Within a phenomenological and collaborative approach, in-depth individual interviews with eight persons with co-occurring conditions were analysed using systematic text condensation. Findings Participants described interpersonal relationships as both supporting and hindering recovery in fundamental ways. Four categories of experiences of relational recovery were described as follows: choosing one’s child; living with loneliness and a painful past; sacrificing everything for one’s partner; and regaining trust and support. Originality/value This paper provides an enhanced understanding of how interpersonal relationships may be experienced by persons who live with co-occurring conditions. The results generally support an understanding of recovery as a relational process.

More than 9 million Americans met diagnostic criteria for both a mental illness and a substance use disorder, according to the latest results of the National Survey on Drug Use and Health (NSDUH). The 2019 NSDUH report, released on Sept. 11, points to a close link between mental health and substance use disorders (SUDs), prompting the need for facilities to treat for all mental health conditions and SUDs, officials stated.

The objectives of this review were to understand the prevalence of cannabis use and how cannabis is associated with transition to psychosis, symptoms, cognition, trauma and family history in clinical high risk (CHR) for psychosis individuals.

PLOS Medicine, 17(7), e1003172. https://doi.org/10.1371/journal.pmed.1003172

Background The “trimorbidity” of substance use disorder and mental and physical illness is associated with living in precarious housing or homelessness. The extent to which substance use increases risk of psychosis and both contribute to mortality needs investigation in longitudinal studies. Methods and findings A community-based sample of 437 adults (330 men, mean [SD] age 40.6 [11.2] years) living in Vancouver, Canada, completed baseline assessments between November 2008 and October 2015. Follow-up was monthly for a median 6.3 years (interquartile range 3.1–8.6). Use of tobacco, alcohol, cannabis, cocaine, methamphetamine, and opioids was assessed by interview and urine drug screen; severity of psychosis was also assessed. Mortality (up to November 15, 2018) was assessed from coroner’s reports and hospital records. Using data from monthly visits (mean 9.8, SD 3.6) over the first year after study entry, mixed-effects logistic regression analysis examined relationships between risk factors and psychotic features. A past history of psychotic disorder was common (60.9%). Nonprescribed substance use included tobacco (89.0%), alcohol (77.5%), cocaine (73.2%), cannabis (72.8%), opioids (51.0%), and methamphetamine (46.5%). During the same year, 79.3% of participants reported psychotic features at least once. Greater risk was associated with number of days using methamphetamine (adjusted odds ratio [aOR] 1.14, 95% confidence interval [CI] 1.05–1.24, p = 0.001), alcohol (aOR 1.09, 95% CI 1.01–1.18, p = 0.04), and cannabis (aOR 1.08, 95% CI 1.02–1.14, p = 0.008), adjusted for demographic factors and history of past psychotic disorder. Greater exposure to concurrent month trauma was associated with increased odds of psychosis (adjusted model aOR 1.54, 95% CI 1.19–2.00, p = 0.001). There was no evidence for interactions or reverse associations between psychotic features and time-varying risk factors. During 2,481 total person years of observation, 79 participants died (18.1%). Causes of death were physical illness (40.5%), accidental overdose (35.4%), trauma (5.1%), suicide (1.3%), and unknown (17.7%). A multivariable Cox proportional hazard model indicated baseline alcohol dependence (adjusted hazard ratio [aHR] 1.83, 95% CI 1.09–3.07, p = 0.02), and evidence of hepatic fibrosis (aHR 1.81, 95% CI 1.08–3.03, p = 0.02) were risk factors for mortality. Among those under age 55 years, a history of a psychotic disorder was a risk factor for mortality (aHR 2.38, 95% CI 1.03–5.51, p = 0.04, adjusted for alcohol dependence at baseline, human immunodeficiency virus [HIV], and hepatic fibrosis). The primary study limitation concerns generalizability: conclusions from a community-based, diagnostically heterogeneous sample may not apply to specific diagnostic groups in a clinical setting. Because one-third of participants grew up in foster care or were adopted, useful family history information was not obtainable. Conclusions In this study, we found methamphetamine, alcohol, and cannabis use were associated with higher risk for psychotic features, as were a past history of psychotic disorder, and experiencing traumatic events. We found that alcohol dependence, hepatic fibrosis, and, only among participants <55 years of age, history of a psychotic disorder were associated with greater risk for mortality. Modifiable risk factors in people living in precarious housing or homelessness can be a focus for interventions.

 

Liu, Y., Ball, J. D., Elliott, A. L., Jacobs-Elliott, M., & Nicolette, G. (2020). Diagnostic sequence of cocaine use disorder in relation to other mental health conditions among college students. Journal of American College Health, 68(6), 575‑578. https://doi.org/10.1080/07448481.2019.1583657

Objective: Cocaine use is increasing. Comorbidities and diagnostic sequencing are needed among college students to inform treatment of cocaine use disorder (CUD). Method: Using electronic medical records from the psychiatric clinic at the student health care center of a large, public university from 2005 to 2015, patients diagnosed with CUD were identified. Their top mental health conditions were identified and assessed to see whether the first diagnosis of these conditions was made (1) before, (2) at the same time as, or (3) after the first diagnosis of CUD. Results: Among the 50 CUD patients, their most common mental health comorbidities were alcohol use disorder, anxiety, depression, and cannabis use disorder. Anxiety and depression were likely to be diagnosed before CUD; alcohol and cannabis use disorders were likely to be diagnosed concurrently with CUD. Conclusion: Diagnostic sequencing can be used to inform screening, workup, and treatment for patients with CUD.

Long after a COVID-19 vaccination is developed and years after the coronavirus death toll is tallied, the impact on mental health will linger, continuing to inflict damage if not addressed, according to new research. A psychology researcher at the University of Houston has published two papers discussing the psychological, addictive and health behavior issues related to the COVID-19 pandemic from a behavioral science perspective.
