Xylazine is a sedative which causes analgesic and muscle-relaxing properties and is approved for veterinary medicine. Xylazine was first produced in 1962 by the Bayer company¹. It has been studied for human use, but clinical trials had to be terminated due to severe adverse side effects, including central nervous system (CNS) depression¹. Xylazine is not approved for human consumption, but it has been found as an adulterant being added to drugs, and it has been used in drug facilitated crimes to induce sleep. According to the DEA, there were 149 reported cases from federal and state laboratories involving xylazine in 2015, but that number jumped to 8,938 in 2021¹.

Some individuals exposed to xylazine may not be aware of its presence. Xylazine has been found as an adulterant in white powder drugs. Primarily xylazine has been detected in heroin and fentanyl supply, though it has also been discovered in some stimulant supply such as methamphetamine and cocaine². Other users actively seek out and use xylazine along with speedball, the street name for a mixture of heroin and cocaine, to mitigate some of xylazine’s negative effects. Xylazine containing products can be marketed on the street as tranq, sleep-cut, Philly-dope, or zombie drug.  

Negative side effects of xylazine include CNS and respiratory depression, hypotension, hypothermia, high blood glucose levels, miosis, hypotension, and necrotic skin ulcerations that can lead to amputation if not treated. Additionally, because xylazine is not an opioid, naloxone is ineffective in the event of an overdose. The FDA issued a safety alert warning in November 2022 about the severe risks associated with the drug³.  

Xylazine is not currently scheduled, though legislation was proposed in March 2023 to make xylazine a Schedule III Substance⁴. Congress has considered scheduling the substance prior to this legislation, but scheduling the drug would significantly impede the veterinary use of the medication⁵. Currently, the FDA is working to more strictly regulate the importation of xylazine and verify the legitimate veterinary supply⁶.

What is Ketamine? 

Ketamine (ketamine hydrochloride) is a dissociative anesthetic with some hallucinogenic effects, meaning it distorts perceptions of sight and sound and makes the user feel disconnected from their environment and any pain.¹ It has one-tenth the potency of PCP, and its original use is as an injectable, short-acting anesthetic for use in humans and animals.⁵ Ketamine can induce a state of sedation (feeling calm and relaxed), immobility, relief from pain, and amnesia (no memory of events while under the influence of the drug).¹ It can be used for the induction (the transition from an awake to an anaesthe-tized state) of general anesthesia as a pre-anesthetic to other general anesthetic agents.² 

Potential Therapeutic Use 

Studies from Yale research labs showed that ketamine triggers “glutamate production,” which can prompt the brain to form new neural connections. This makes the brain more adaptable and able to create new pathways, giving patients the opportunity to “develop more positive thoughts and behaviors.” This was an effect that had not been seen before, even with traditional antidepressants.⁴ For the last two decades, researchers at Yale have led ketamine research by experimenting with using small doses of ketamine delivered intravenously in controlled clinical settings for patients with severe depression who have not improved with standard antidepressant treatments. In several studies, more than half of participants (who felt other antidepressant medications were ineffective) showed a significant decrease in depression symptoms after just 24 hours. The study states that ketamine “needs to be part of a more comprehensive treatment plan.”⁴ Studies are continuing to explore the possibilities of ketamine in therapeutic settings. It is not unlikely to assume that as ketamine gets clinically used, it will unfortunately also be under threat of being abused or misused. 

Ketamine Misuse 

Much like its intended use, ketamine can be misused recreationally for its ability to produce dissociative sensations and hallucinations. In 2022, the American Addiction Centers reported that nonmedical misuse is relatively low, with 0.7% of the U.S. population using it illegally.⁶

Since ketamine can be used in powdered form, it has been known to be snorted as a “party drug” at festivals or rave events.³ The street name for ketamine is “K” or “Special K.” 

Ketamine has also been used to facilitate sexual assault because of its hallucinogenic effects known to make the user feel disconnected from their surroundings. A number of individuals have abused this drug or have been instrumental in others using this drug as a “date-rape” drug.¹ 

Recreational use of ketamine can result in a number of internal complications including:

• gastrointestinal issues; 
• depression; 

• respiratory problems and; 
• amnesia 

Serious debilitating urinary tract symptoms are also seen frequently in those individuals who abuse ketamine.³ A study on ketamine in the National Institutes of Health predicts that ketamine toxicity and addiction “pose significant risks to a small segment of the population, and given increasing utilization, the prevalence of these phenomena is expected to increase.⁵” As ketamine use increases both recreationally and clinically, it will continue to be a substance worth testing for. 

USDTL Testing 

As an innovative leader offering alcohol and other drug testing, we understand the importance of being able to test when it is most feasible for your organization. We offer extended panel testing for ketamine in alternative specimens including hair, nail, and urine.

Psychedelics are a subclass of hallucinogens that produce changes in perception, mood, and cognitive processes. The most popular psychedelics include lysergic acid diethylamide (LSD), psilocybin, mescaline, and dimethyltryptamine (DMT).  

Where Do They Come From 

Psilocybin and mescaline are naturally occurring and produced from fungi and the Mexican peyote cactus, respectively.¹ LSD, on the other hand, is chemically synthesized. DMT can be chemically synthesized, but most commonly is extracted from a variety of different plants.

Usage Over Time 

Psychedelic use dates back as early as 4000 BC, with evidence of psilocybin and mescaline being used in religious ceremonies.² DMT was first synthesized in 1931, while LSD was first synthesized in 1943. Both LSD and DMT gained popularity in the 1960s and then in the early 1970s were classified as Schedule 1 drugs.³ Mescaline and psilocybin followed suit and were classified as Schedule 1 drugs in 1971.  

After the psychedelics became scheduled, there appeared to be a decrease in usage, but more recently psychedelic use has been on the rise. LSD use rose from 0.55% in 2015 to 0.86% in 2018.⁴ While overall usage of LSD is still low, that was a 56 percent increase in usage over just 3 years. Psilocybin use has also been on the rise: 8.5% of adults reported usage in 2016, while 9.6% of adults reported usage in 2018.⁵ Less is known about DMT and mescaline trends, though one study reports mescaline usage has decreased from 2002-2019.⁶ 

Getting More Mainstream 

We may expect to see a further increase in psychedelic usage due to the increasing popularity of microdosing.⁷ Microdosing is periodically ingesting minute quantities of psychedelic drugs as a performance-enhancing activity. The levels of psychedelics consumed are so low that a hallucinogenic effect is not experienced, but users report feeling improved mood and focus. There is no scientific literature supporting or refuting the effects of microdosing.

The increased usage of psychedelics is accompanied with mainstream media on the subject. Hulu released a limited series entitled Nine Little Strangers in which the main character, a host at a luxurious wellness retreat in California, microdoses her guests without their knowledge or consent. The creator of the series was reported as stating that he hopes the series will help these types of therapies go mainstream .⁸ Similarly, Netflix released a movie entitled Have a Nice Trip in which celebrities reminisce about the experiences they had while under the influence of psychedelics. The movie normalizes and makes light of psychedelic usage while failing to mention any of the dangers or negative effects the users may experience. Additionally, just like with marijuana, retail companies have launched apparel and accessories with symbols and designs relating to psychedelics.  

Currently, psychedelics are still illegal, but that may soon change. Psilocybin is currently being researched and may receive FDA clearance for the treatment of depression.⁹ Experts predict the FDA may approve the therapeutic use of psilocybin and MDMA (for PTSD) in as little as 1-2 years. This possible shift in legislation has the potential to change many aspects of the pharmaceutical and drug industry.

When drugs are swallowed, they may be broken down (metabolized) by enzymes and/or absorbed using transporters in cells found in the small intestine. Grapefruit juice can cause problems with these enzymes and transporters, causing too much or too little drug in the body.

Some drugs, like statins used to lower cholesterol, are broken down by enzymes. Grapefruit juice can block the action of these enzymes, increasing the amount of drug in the body and may cause more side effects.

Other drugs, like Allegra (fexofenadine) used to treat allergies, are moved by transporters into the body’s cells. Grapefruit juice can block the action of transporters, decreasing the amount of drug in the body and may cause the drug to not work as well.

These days, having a “drink” can be deceiving. The alcohol content can vary drastically from one drink to the next.

A standard drink is any beverage that contains 14g (0.6) of pure alcohol. Amounts vary depending on the percentage of Alcohol by Volume (ABV).

Blood alcohol concentration levels for 6 drinks within 12 hours can differ greatly depending on drinking behavior and individual metabolism.

The National Institute on Alcohol Abuse and Alcoholism (NIAAA) defines binge drinking as a pattern of drinking that brings a person’s blood alcohol concentration (BAC) to 0.08 grams percent or above. This typically happens when men consume 5 or more drinks and when women consume 4 or more drinks in about 2 hours.

The Bottom Line

Self-report screening of maternal drinking during pregnancy is currently the standard test for monitoring maternal alcohol consumption and identifying alcohol-exposed newborns. However, misinformation on what defines binge drinking means self-report may not be reliable.

Alcohol biomarkers can be used as objective measurements for monitoring maternal alcohol consumption and screening for prenatal alcohol exposure.
