It’s certainly true alcohol and antidepressants don’t mix; what about antidepressants and weed? It’s a simple fact that many people smoke weed, so it’s only natural that people, especially those prescribed antidepressants such as Zoloft, may ask something like: “can you smoke weed on Zoloft?” The answer to that question is: you can, but that doesn’t mean you should. Read on to learn more.
What Is Zoloft (Sertraline)?
Zoloft is the brand name for sertraline, a type of antidepressant known as a selective serotonin reuptake inhibitor (SSRI). It works by increasing the levels of serotonin—a neurotransmitter that helps regulate mood—in the brain. Zoloft is FDA-approved to treat major depressive disorder (MDD), generalized anxiety disorder (GAD), panic disorder, post-traumatic stress disorder (PTSD), social anxiety disorder, obsessive-compulsive disorder (OCD), and premenstrual dysphoric disorder (PMDD).
Because of its broad range of applications and generally favorable safety profile, Zoloft is widely used as a first-line treatment for various mood and anxiety disorders. However, one of the most important things to be aware of when it comes to antidepressants, or any medication, is the possible interactions they can have with other drugs. This is especially true when it comes to illicit substances like marijuana; mixing Zoloft and marijuana can bring on a variety of side effects.
How Weed Affects the Brain and Body
Weed, also known as marijuana or cannabis, affects the brain and body primarily through its active compound, THC (tetrahydrocannabinol). THC interacts with the body’s endocannabinoid system, which plays a role in regulating mood, memory, appetite, and pain sensation. In the brain, THC binds to cannabinoid receptors, especially in areas responsible for coordination, judgment, and pleasure, which can result in euphoria, altered perception of time, and impaired short-term memory. There are several kinds of THC, including Delta-8 and Delta-9.
Physically, weed can increase heart rate, dry out the mouth and eyes, and affect motor skills. While many people use marijuana recreationally or medicinally for pain, anxiety, or sleep issues, chronic or heavy use—especially in adolescents—may negatively impact brain development, mental health, and motivation.

It’s possible you can smoke marijuana on Zoloft, but this isn’t the best idea. First, if you’re taking Zoloft for anxiety, your doctor probably wants to see how you react to that drug and whether it is helping your condition, which is difficult if you’re also consuming other substances.
But more importantly, it appears marijuana can inhibit your body’s ability to metabolize antidepressants. One 2021 study on marijuana and Zoloft found that, it slowed the breakdown of citalopram (Celexa) and escitalopram (Lexapro), leading to higher levels of those drugs in the body. The study notes that the breakdown of sertraline did not appear to be affected.
However, another study on antidepressants and weed from the same year did find that THC (and CBD) affect concentrations of SSRIs in the blood – including sertraline. This could raise a person’s risk of experiencing blood-level-related SSRI side effects.
Potential Interactions Between Zoloft and Weed
Marijuana use may interact with Zoloft in other ways, such as by impacting neurotransmitters in the brain. Both THC and Zoloft affect the brain’s chemistry—Zoloft by increasing serotonin levels and weed primarily through THC’s effects on the endocannabinoid system. When combined, they can amplify side effects such as dizziness, drowsiness, anxiety, and impaired judgment. In some cases, using weed with Zoloft may worsen symptoms of depression or anxiety, interfere with the effectiveness of the medication, or increase the risk of serotonin syndrome—a rare but serious condition. Recent case studies have even emerged of marijuana itself causing this condition, speculated to be due to the rise of more powerful strains of marijuana (ex: “dro“) and powerful THC edibles.
If you’re considering using cannabis while on Zoloft, it’s important to speak with a healthcare provider to understand the potential risks and how they may affect your specific situation.
Other Zoloft Drug Interactions
Zoloft can interact with a variety of medications, which may increase the risk of side effects or reduce the drug’s effectiveness.
Some of the most important Zoloft drug interactions include:
- Other antidepressants: Combining Zoloft with other SSRIs, SNRIs, or MAOIs can raise the risk of serotonin syndrome, a potentially life-threatening condition caused by too much serotonin in the brain.
- Blood thinners: Medications like warfarin or aspirin may increase the risk of bleeding when taken with Zoloft.
- NSAIDs: Drugs such as ibuprofen or naproxen can also raise bleeding risks when used with Zoloft.
- Benzodiazepines: When taken together, Zoloft and medications like Xanax or Ativan may cause increased sedation or drowsiness.
- Anticonvulsants: Medications like phenytoin or carbamazepine may interfere with Zoloft’s effectiveness or increase side effects.
- Alcohol: Drinking while on Zoloft can intensify side effects like dizziness, drowsiness, and impaired judgment.
- St. John’s Wort: Combining St. John’s Wort with Zoloft can increase the risk of serotonin syndrome.
Always consult a healthcare provider before mixing Zoloft with other medications or supplements to avoid harmful interactions.

Check Your CoverageRisks of Mixing Zoloft and Marijuana
Mixing Zoloft (sertraline) with marijuana can lead to unpredictable and potentially harmful effects. Both substances impact brain chemistry—Zoloft by altering serotonin levels, and marijuana through its interaction with the endocannabinoid system.
When used together, they may increase the risk of side effects such as:
- Increased anxiety or paranoia – THC in marijuana can worsen anxiety or panic, especially in those with underlying mental health conditions.
- Drowsiness and impaired coordination – Being sedatives, both marijuana and Zoloft can slow reaction times, raising the risk of accidents.
- Mood instability – Marijuana may blunt or interfere with the mood-stabilizing effects of Zoloft, potentially worsening depression or anxiety over time.
- Cognitive impairment – Using the two together can lead to problems with memory, focus, and decision-making.
- Serotonin syndrome – While uncommon, combining substances that affect serotonin levels—including Zoloft and possibly certain cannabinoids—could increase the risk of this serious condition.
Because of these risks, it’s important to talk to your doctor before using marijuana while taking Zoloft. They can help you weigh the potential dangers and monitor for any negative effects.

While it may be possible to use marijuana while taking Zoloft, doing so carries significant risks that shouldn’t be ignored. Both substances affect brain chemistry in different ways, and their interaction can lead to side effects like increased anxiety, drowsiness, impaired coordination, and in rare cases, serotonin syndrome. It’s likely a good idea to stop using marijuana entirely if you’re on antidepressants. If you feel you can’t, perhaps consider seeking dual diagnosis treatment at a mental health treatment center in Oklahoma City for anxiety and addiction issues..
When in doubt, prioritize safety — don’t hesitate to seek the help you deserve for any mental health or addiction issues.
