Let’s delve into four distinct perspectives: the medical viewpoint, the skeptical stance, the newcomer’s curiosity, and the experienced user’s wisdom. ### The Medical Perspective Recent studies indicate a general decline in opioid and barbiturate positivity rates in the same tests. This suggests a potentially momentous shift towards cannabinoid-based treatments, which often offer a more manageable side-effect profile than traditional pharmaceutical options ### The Skeptical Viewpoint about Rising Marijuana Positivity Rates For those skeptical about marijuana’s therapeutic potential, it’s important to note that a positive test doesn’t necessarily equate to on-the-job impairment. Drug screens can detect usage from as far back as a month. Employers have to navigate the labyrinthine mix of federal and state laws, which adds a layer of complexity to employee testing and subsequent actions. ### The Newcomer’s Curiosity Newcomers might be intrigued by the National Basketball Association’s new stance: removing marijuana from its prohibited-substance list starting the 2023-24 NBA season. For those unfamiliar with medicinal cannabis, this highlights the shift in social attitudes and may prompt further inquiry into the growing body of published [cannabis research](https://cedclinic.com/pediatric-cannabis-certification-care-children/). ### The Experienced User’s Wisdom For veterans in the medicinal cannabis community, the increased rates of marijuana positivity are less of a ‘new phenomenon’ and more of a ‘return to normal’. Cannabis has been a part of human history, and the tide seems to be turning back towards natural, cannabinoid solutions over pharmaceutical ones. ### Clinical Perspective: Meet Sarah, a patient at CED Clinic struggling with chronic pain. For years, she relied on opioids, until the side effects became unbearable. With cannabinoid therapy, Sarah experienced symptomatic relief and improved quality of life. It’s a privilege to contribute to this field, alongside scientific collaborators and my patients. My forthcoming book, *The [Doctor-Approved Cannabis](https://cedclinic.com/doctor-approved-cannabis-handbook-endorsements/) Handbook*, aims to address these very issues.  Read Sarah’s story on page 249 of the book!

This change is affecting everyone—from the medical community to employers, from cannabis newcomers to experienced users. #### From Opioids to Cannabinoids From a medical standpoint, this spike could indicate a cultural and medical shift away from traditional opioids and barbiturates towards cannabinoids. Multiple studies have shown that cannabinoids often present fewer side effects than these more traditional substances[4]. #### Redefining Impairment Skeptics must grapple with the fact that marijuana positivity does not necessarily correlate with immediate impairment. Legal complexities at the federal and state levels add to the challenge of interpreting these tests. As [cannabis legalization](https://cedclinic.com/the-forgotten-history-of-hemp-in-america/) spreads, laws may need to adapt to better assess on-the-job impairment rather than historical use[5]. #### Cultural Acceptance The NBA’s new policies on cannabis reflect changing social norms, influencing newcomers to cannabis and hinting at a broader societal acceptance. This may lead to greater interest and engagement in the scientific community’s growing body of cannabis research[6]. #### A Return to Roots For experienced users, this trend is more of a return to normalcy than a radical change. The increasing preference for natural cannabinoid solutions is seen as a positive development that aligns with historical use and understanding of the plant. #### Bridging Gaps in Clinical Practice From a clinical perspective, the stories of patients like Sarah highlight the promising therapeutic potential of cannabis. Through published research, clinical experience, and educational resources like The Doctor-Approved Cannabis Handbook, healthcare providers and patients alike can make more informed decisions about cannabinoid therapies[7]. In summary, the surge in workplace marijuana positivity rates is not an isolated phenomenon. Rather, it reflects evolving perspectives on cannabis, influenced by medical research, cultural shifts, and individual experiences. This change has implications for legal frameworks, workplace policies, and healthcare practices. #### References 1: “Decline in opioid and barbiturate positivity rates in workplace drug tests,” Journal of Occupational Medicine and Toxicology, 2021. 2: Moeller, K.

Based on a news article by Anne Marie Chaker, published on May 18, 2023, we’re examining the top 10 things you need to know about this growing trend. ## 1. Record-Breaking Positivity Rates More than 6 million general workforce tests screened for marijuana in 2022 showed that 4.3% came back positive, which is the highest rate since 1997. ## 2. Post-Accident Rates Soar The percentage of employees testing positive for marijuana following an on-the-job accident rose sharply to 7.3% in 2022. ## 3. Opioid and Barbiturate Rates Decline Contrastingly, positivity rates for certain classes of opioids and barbiturates declined last year. ## 4. Rising Amphetamine Positivity Besides marijuana, tests for amphetamines also showed an increase in positivity, rising from 1.3% in 2021 to 1.5% in 2022. ## 5. State Vs. Federal Law Complications The growing number of U.S. states legalizing marijuana use adds complexity to workplace drug testing policies, as federal laws may still require testing. ## 6. Shift in Employer Screening Policies Companies like ManpowerGroup are starting to screen less often for marijuana, partly due to the challenges of hiring enough front-line workers. ## 7. NBA’s Progressive Stance The NBA is removing marijuana from its prohibited substance list for the 2023-24 season, signaling a shift in social attitudes towards marijuana use. ## 8. Amazon’s Inclusive Approach Amazon has stopped screening many job applicants for marijuana, citing that the tests disproportionately impact people of color. ## 9. Employee Impairment Challenges Because some drug screens can detect marijuana use that goes back days or even weeks, a positive test does not necessarily indicate on-the-job impairment. ## 10. The Impact on Various Industries The rise in marijuana positivity rates isn’t restricted to one sector; it spans multiple industries including food services, retail, and accommodation. ## Summary The surge in workplace marijuana positivity rates reflects broader societal shifts in attitude towards cannabis, but it also introduces complexities for employers navigating drug testing policies. While some companies are reevaluating their approach to marijuana screening, debates around safety and legal liabilities continue. Overall, the rise poses challenges and opportunities in workforce management, health, and social policy. ## Citations ## Note Points 1-8 are extracted from the news article “American Workers Testing Positive for Marijuana Reaches 25-Year Record” by Anne Marie Chaker, published on May 18, 2023.
