The Twin Epidemic: Rising Co-Prescriptions of Opioids and Stimulants in the U.S.

A recent 10-year longitudinal cohort study has unveiled concerning trends in the co-prescription of opioids and stimulants, shedding light on the escalating “twin epidemic” in the United States.

Key Findings:

  • Prevalence of Co-Prescription: Approximately 5.5% of patients received both opioid and stimulant prescriptions during the study period. 
  • Increased Opioid Dosage: Patients co-prescribed stimulants were more likely to escalate their opioid doses over time, with the highest doses observed in the South and West regions.
  • Associated Conditions: Common diagnoses among these patients included depression, anxiety, attention-deficit/hyperactivity disorder (ADHD), and chronic pain

Implications:

The concurrent use of opioids and stimulants poses significant risks, including increased chances of overdose, cardiovascular events, and mental health complications. This study emphasizes the need for healthcare providers to carefully consider the implications of co-prescribing these medications and to monitor patients closely.

Call to Action:

It’s crucial to raise awareness about this emerging twin epidemic. Healthcare professionals, policymakers, and patients must collaborate to develop strategies that mitigate risks associated with co-prescriptions and ensure safer prescribing practices.

New ASAM and AAAP Guidelines for Stimulant Use Disorder: Key Updates

The American Society of Addiction Medicine (ASAM) and the American Academy of Addiction Psychiatry (AAAP) recently released updated guidelines for the treatment of stimulant use disorder (SUD).

  1. Comprehensive Assessment: The guidelines emphasize a thorough assessment of patients, including the use of validated screening tools to diagnose SUD, assess severity, and identify co-occurring mental health disorders.
  2. Evidence-Based Psychosocial Interventions: Behavioral therapies remain the cornerstone of treatment. Cognitive-behavioral therapy (CBT), contingency management (CM), and motivational interviewing (MI) are recommended due to strong evidence of their efficacy.
  3. Pharmacological Treatments: While no medications are currently FDA-approved specifically for stimulant use disorder, the guidelines discuss off-label use of medications like bupropion and naltrexone, which show promise in reducing stimulant use and cravings in some patients.
  4. Harm Reduction Strategies: Recognizing the importance of harm reduction, the guidelines support interventions like needle exchange programs and education on safer use to reduce the risk of infectious diseases and other health complications.
  5. Integrated Care Models: The guidelines highlight the importance of integrated care that combines medical, psychiatric, and social support services, aiming to provide holistic care tailored to individual patient needs.
  6. Special Populations: Specific recommendations are provided for treating special populations, including pregnant individuals, adolescents, and those with co-occurring mental health disorders, recognizing the unique challenges these groups face.
  7. Recovery Support: Emphasis is placed on long-term recovery support, including peer support groups, vocational training, and housing assistance, to help individuals maintain recovery and improve their quality of life.

These guidelines represent a significant step forward in the standardization of care for individuals with stimulant use disorder, aiming to improve outcomes through evidence-based, patient-centered approaches. For clinicians, staying informed and implementing these recommendations can greatly enhance the quality of care provided to this population.

ADHD and Cannabis Use Disorder: Key Facts You Shouldn’t Ignore

1. Prevalence and Patterns of Use

People with ADHD have been shown to use cannabis at higher rates than those without ADHD. Studies indicate that adolescents and adults with ADHD are more likely to use cannabis, and they may start using it at a younger age. This may be due to self-medication attempts, as people with ADHD often report using cannabis to help with symptoms like impulsivity, anxiety, and sleep difficulties which seems like a bad idea to me but lets look at the reasons.

2. Cannabis as a Self-Medication Attempt

Some people with ADHD use cannabis in an attempt to self-manage their symptoms. Anecdotally, users report feeling more focused, relaxed, and less anxious, though the scientific evidence on cannabis’s effectiveness for ADHD symptom management is not robust. Studies show that while some ADHD symptoms like restlessness might feel alleviated short-term, long-term outcomes often do not show sustained benefit, and impairment can increase over time.

3. Impact on ADHD Symptoms

Research on cannabis’s effect on ADHD symptoms is mixed:

  • Impulsivity and Attention: Cannabis can impair attention, memory, and executive functioning, which are already areas of struggle for individuals with ADHD. Heavy cannabis use is associated with poorer performance on tasks measuring these cognitive domains.
  • Cognitive Function: Longitudinal studies have shown that chronic cannabis use can worsen cognitive functions over time, especially if use begins in adolescence. These cognitive impacts may compound ADHD-related deficits.
  • Motivation and Goal-Directed Behavior: Cannabis can affect motivation and goal-directed behavior, which can exacerbate some ADHD symptoms, particularly in individuals who already struggle with organization and task completion.

4. ADHD as a Risk Factor for Cannabis Use Disorder

Studies suggest that people with ADHD may be more prone to developing cannabis use disorder (CUD) compared to the general population. Traits like impulsivity and sensation-seeking, common in ADHD, may increase vulnerability to addiction. Additionally, the reinforcing effects of cannabis (e.g., reduction in perceived anxiety) may lead to increased use and dependency in those with ADHD.

5. Genetic and Neurobiological Factors

There is some evidence suggesting that the overlap between cannabis use and ADHD may have a genetic or neurobiological basis:

  • Genetic Overlap: Studies have found that genes linked to ADHD, particularly those affecting dopamine function, are also implicated in substance use disorders, including cannabis use disorder.
  • Endocannabinoid System: ADHD and cannabis use affect dopamine and endocannabinoid systems. Some research posits that dysregulation in these systems might underlie both the propensity for ADHD and substance use, but this remains an area for further research.

6. Cannabis and Medication Interactions

For those with ADHD taking stimulant medications, cannabis use can interfere with treatment. THC, the psychoactive component of cannabis, can interact with medications like methylphenidate or amphetamine-based treatments, potentially reducing their effectiveness or exacerbating side effects like anxiety and heart palpitations.

7. Longitudinal and Population Studies

Long-term studies generally show that early and heavy cannabis use is associated with worse outcomes for individuals with ADHD. These include lower academic achievement, increased rates of unemployment, and higher incidences of mental health issues, especially when cannabis use starts in adolescence.

Summary

While some people with ADHD report short-term symptom relief with cannabis, research shows that heavy, frequent use tends to worsen cognitive deficits associated with ADHD over time. Additionally, ADHD may predispose individuals to higher rates of cannabis use and a greater risk of developing cannabis use disorder. While cannabis might seem beneficial for symptom relief in the short term, its long-term use is generally not supported as an effective management strategy for ADHD.
