Addictions Update
By:  David Lott, MD 

In order to keep our readership informed, I want to give several updates relating to substance use disorders.  At the top of the list is opioids, with a continuing rise in overdose deaths, worsened further by the COVID-19 pandemic.  For instance, Illinois saw a 36% increase in overdose deaths in Jan-Sep 2020 compared to the same time period in 2019 (1).
 
Fentanyl analogues and other illicit synthetic opioids continue to fuel the rise in opioid use and deaths, though other factors also play a role. As in many other areas, the increase in Illinois is disproportionately affecting Black and Hispanic people, one more example of the vast racial inequities we face. Identifying and combating structural racism is a key part of addressing this crisis.
 
There are several highly effective treatments for opioid use disorder – particularly buprenorphine, methadone, and naltrexone (collectively known as MOUD - medications for opioid use disorder), but they are underutilized.  Often people with OUD are ready to make a change but cannot get help, and limited availability of MOUD is one of the major barriers for patients who are seeking treatment. ASAM and other groups have recently tried to improve MOUD access by advocating for elimination of the X-waiver required for buprenorphine prescribing. In response, in late April, the U.S. Department of Health and Human Services (HHS) issued an exemption which now allows providers to prescribe buprenorphine for up to 30 patients without an X-waiver.
 
Another important recent development in Illinois is recreational cannabis, which became available in 2020. It is too soon to know what the impact of this will be on rates of cannabis use, cannabis use disorder, and related psychiatric symptoms. Illinois rates of cannabis use were already increasing for over a decade before this (per NSDUH annual survey past year cannabis use data), and we do not know yet whether the availability of recreational cannabis will impact this further.  Another unknown is the impact on side effects such as psychosis. If use rates continue to increase, and products continue to increase in potency, then there is a good possibility that this will translate into higher rates of psychosis. In fact, recent studies have demonstrated a dose-response relationship with psychosis (2,3).
 
There are many other trends worth mentioning – telemedicine, rising stimulant use, ketamine and hallucinogens as treatments, vaping, and more – but I want to spend the last portion of this article on alcohol. Rates of alcohol use have increased steadily for several years now, a trend that appears to have continued during the pandemic (4,5,6). Unfortunately, this increase in alcohol use is happening at the same time as studies are showing more negative health effects of alcohol use. For instance, a recent study from Oxford, though not yet peer-reviewed, received widespread media coverage in May after showing negative effects on brain fMRI measures with even modest amounts of alcohol consumption (7).  Other possible negative effects linked to alcohol include dementia, some cardiovascular diseases, and a variety of cancers (8,9,10). 
 
Another harmful effect of alcohol is on the developing fetus.  With increasing alcohol use rates, there is also an expected increase in alcohol exposure during pregnancy. Growing awareness of the negative effects of prenatal alcohol exposure is reflected in the use of the term Fetal Alcohol Spectrum Disorders (FASD) and other similar constructs that identify alcohol effects not meeting full criteria for Fetal Alcohol Syndrome (FAS). In addition, DSM-5 included Neurobehavioral Disorder associated with Prenatal Alcohol Exposure (ND-PAE) as a condition requiring further study (11). These and other similar diagnostic terms are notable for the ongoing significant developmental and neurobehavioral deficits in affected children (12).  Considering the long-term impact of such cognitive and behavioral problems on individuals, families, and communities, it is clear these effects will persist for many years to come.
 
These substance-related problems and trends are pressing issues for all of us, and I hope each of you will continue to keep updated on them. One good way to stay informed is the Providers Clinical Support System or PCSS (https://pcssnow.org), where you can find up-to-date information, free CME content, and even sign up for a newsletter. This is a group funded by SAMHSA and led by AAAP (American Academy of Addiction Psychiatry), which is the subspecialty professional group for Addiction Psychiatry. AAAP itself also provides many educational opportunities for interested providers, as does the American Society of Addiction Medicine (ASAM). I encourage each of you to use some of these resources to stay informed on all these important issues.
