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.

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.

Selective serotonin reuptake inhibitors (SSRIs) are a class of drugs that can be used to treat depression, anxiety, or other psychological disorders. SSRIs function by blocking the reabsorption of serotonin into neurons, causing an artificially high level of serotonin in the brain. The first SSRI, fluoxetine, was introduced into the market in 1988 as a safer alternative to tricyclic antidepressants (1). From 2015-2018, 13.2% of adults used antidepressants, and SSRIs account for approximately 70% of antidepressants prescribed (2,3). 

Approximately 5.5% of pregnant women in North America used SSRIs during their pregnancy in 2019 (4). The medical opinion on the safety of taking SSRIs during pregnancy is complex. Untreated mental illness of an expecting mother can be a threat to the developing fetus, with an increased risk of preterm birth and low birth weight (5). Additionally, the babies of untreated depressed mothers can have been exposed to higher levels of cortisol, which increases the baby’s risk of developing mental illness later in life.  

However, SSRI use during pregnancy might pose a risk to the developing fetus since about 30 percent of babies exposed in-utero will experience neonatal abstinence syndrome upon birth (5). Additionally, some studies have suggested SSRI use during pregnancy can be linked to an increased risk of persistent pulmonary hypertension, which is a birth defect affecting the baby’s lungs. Further studies have linked using a specific SSRI, paroxetine, during pregnancy to cardiac, brain, and abdominal birth defects (6). Still, other studies draw no link between SSRI use during pregnancy and adverse fetal outcomes. Overall, the various studies on SSRIs and their safety during pregnancy are conflicting, and more data is needed to draw more reliable conclusions.
