The 2018 passing of the bipartisan Farm Bill legalized the production of hemp on an industrial scale for the first time in the U.S. — which means it’s that the CBD industry will only continue to grow. However, this doesn’t necessarily mean there will be more oversight or required research.
The reason for this is that CBD inhibits two main enzyme systems, Grinspoon explains. Enzymes are proteins that speed up chemical reactions in the body, and play an important role in functions like digestion and respiration. They also help you metabolize antidepressants. “One system is the same one that grapefruit inhibits — the technical name is the CYP34A enzyme system. So, just like grapefruit juice, CBD can cause your body to have higher doses of benzodiazepines [anti-anxiety medications], or certain antipsychotic medications,” Grinspon explains.
There’s no denying that CBD, aka cannabidiol, has been the reigning trend of the last few years, and shows no signs of stopping. From edible products and tinctures, to bath and beauty products, CBD was (and is) everywhere. Though touted as a natural, holistic, and safe way to manage a variety of health issues, you may be wondering if you can take CBD and antidepressants together. And while CBD is touted as an all-natural supplement with some evidence that it can be good for your health, it’s possible that your CBD latte can still impact the efficacy of different medications — including antidepressants.
What’s more, Grinspoon says that CBD also inhibits “the system that metabolizes a lot of serotonin reuptake inhibitors (SSRIs), tricyclic antidepressants, and antipsychotics as well.” Meaning, taking CBD supplements while on these psychiatric medications could hypothetically interfere with how these medications are metabolized.
When it comes down to it, Grinspoon says that the potential interactions should be regarded as more “hypothetical than real,” and that the side effect profile of CBD is “very minimal.” Of course, it’s always good to have a conversation with your physician about potential interactions, and to disclose any prescribed or over-the-counter medications and supplements you are taking. At the end of the day, using CBD supplements while on antidepressants is an individual choice, but it’s important to go in informed.
The conclusions that can be drawn? You should, of course, talk to your doctor before taking any new medications (prescription or non-prescription). If you combine Zoloft with either CBD or weed, however, you should be fine. Just be careful, because you could end up more zoned out than you expect.
The rest of the “knowledge” that exists about combining CBD and SSRIs like Zoloft isn’t really knowledge. It’s mostly anecdotal evidence and common sense.
Drug interaction databases note that both CBD and Zoloft can cause some of the same side effects, like drowsiness, dizziness, and loss of concentration. So using them together can potentially increase the severity of those side effects. They only classify the interaction as “moderate,” though, meaning you should simply be careful when mixing the two drugs, and watch carefully for negative effects until you know how you’re affected.
Cannabinoids and Zoloft: What We Know
Nearly 35 million Americans are considered “regular users” of marijuana, with another 20 million said to indulge occasionally. As you undoubtedly know, pot contains a number of cannabinoids – not just THC, but also CBD.
There has only been one rigorous medical review examining the effects of combining Zoloft (or similar SSRIs) and CBD use. It was done at the University of Connecticut and considered all the evidence involving concurrent use of antidepressants (“psychotropic” drugs) and psychoactive drugs like cannabis.
Needless to say, there’s a decent amount of crossover between those taking Zoloft and those consuming CBD. That’s even easier to believe when you consider that:
They say that maybe because those who use pot are afraid to report any problems they may experience. However, doctors prescribe newer generations of psych meds (like Zoloft) because they’re much less likely to cause drug interactions, so the researchers believe it’s very possible that harmful interactions with CBD or THC are “relatively rare or do not happen.”
However, additional data on CBD drug interactions indicate the risk of an interaction between CBD and Zoloft specifically is low.
Zoloft (sertraline), an SSRI (Selective Serotonin Re-uptake Inhibitor), is metabolized extensively by a variety of CYP enzymes, including:
Cannabidiol, also known as CBD, is a major component of cannabis (i.e. marijuana).
With this, it is important to consider potential drug interactions with prescription medication.
Due to the relatively recent nature of CBD use for medicinal purposes, there is a distinct lack of studies when it comes to potential drug interactions between CBD and prescription medication, like Zoloft (sertraline).
While THC (delta-9-tetrahydrocannabinol) is likely more well-known due to its psychoactive and euphoric effects, CBD makes up almost 40% of cannabis extracts and has a wide range of potential benefits when used medicinally, although more studies are certainly needed to better understand the compound.
In addition, since Zoloft is metabolized in the body by a number of enzymes, it is thought that it would be difficult for a single agent to cause a clinically significant interaction. In the words of one study:
