Can You Take Medical Marijuana and Ozempic Together?

If you’re using Ozempic to manage diabetes or support weight loss and are also considering medical cannabis for pain, anxiety, or other conditions, you may be wondering: Is it safe to use both at the same time?

The short answer: In many cases, yes—but it’s important to understand how they work, how they might interact, and what to watch out for. Let’s explore what we know about using medical marijuana and Ozempic (semaglutide) together, so you can make safe, informed choices about your care.

What Is Ozempic?

Ozempic (semaglutide) is a prescription medication originally developed to treat type 2 diabetes. It helps regulate blood sugar levels by mimicking a natural hormone called GLP-1 (glucagon-like peptide-1). This slows digestion, reduces appetite, and increases insulin release after eating.

More recently, Ozempic has gained attention as a weight-loss aid. Many people using it experience decreased hunger, smaller portion sizes, and gradual, sustainable weight loss.

What Is Medical Cannabis Used For?

Medical marijuana contains compounds like THC (tetrahydrocannabinol) and CBD (cannabidiol) that interact with the body’s endocannabinoid system. It’s widely used to treat symptoms such as:

• Chronic pain

• Anxiety and PTSD

• Insomnia

• Nausea and vomiting

• Appetite issues

• Muscle spasms

Depending on the formulation and strain, cannabis can have stimulating, calming, or pain-relieving effects. Some patients also use it to manage symptoms of diabetes, such as neuropathy or poor sleep.

Can You Use Medical Cannabis and Ozempic Together?

There are no known serious drug interactions between Ozempic and cannabis. That’s good news—but it doesn’t mean they don’t affect each other in more subtle ways. Here’s what to consider if you plan to use both:

---

1. Cannabis May Increase or Decrease Appetite—Opposite Ozempic’s Effects

One of Ozempic’s main benefits is appetite suppression, which helps with weight loss. On the other hand, THC-dominant cannabis strains are known for causing the “munchies,” or increased appetite.

This opposing effect can vary widely depending on the person, dose, and type of cannabis. If you’re using Ozempic to control your eating habits, be cautious with high-THC strains that might increase cravings.

Pro tip: Look for CBD-dominant or balanced THC:CBD strains, which are less likely to increase appetite.

---

2. Cannabis May Help Manage Nausea or GI Discomfort from Ozempic

A common side effect of Ozempic is nausea, especially in the first few weeks. For some, this can be unpleasant enough to interfere with meals or medications.

Cannabis—especially CBD-rich strains or low-dose THC products—may help ease nausea and improve comfort. It can also help settle the stomach, especially when taken in small, controlled amounts.

---

3. Watch for Low Blood Sugar (Hypoglycemia)

If you have diabetes and use Ozempic, you may already be monitoring your blood sugar closely. Cannabis can alter awareness of hunger and sometimes lead to less predictable eating patterns. If you’re skipping meals or eating less (intentionally or not), you could be at risk for low blood sugar episodes—especially if using insulin or other glucose-lowering medications.

Be mindful of how both medications affect your appetite and check blood sugar regularly if you’re managing diabetes.

---

4. Cannabis and Ozempic Both Affect Digestion—Expect Some Changes

Both Ozempic and cannabis can slow digestion, though by different mechanisms:

• Ozempic delays stomach emptying as part of its GLP-1 action.

• Cannabis may reduce GI motility or alter gut perception.

This combination can sometimes lead to mild bloating, constipation, or early satiety (feeling full quickly). Staying hydrated, eating fiber-rich foods, and adjusting your cannabis dosage may help.

5. Cognitive Effects of Cannabis Matter

While Ozempic doesn’t affect thinking or coordination, THC-heavy cannabis products can. If you’re trying to maintain a consistent diet or medication schedule, avoid high doses of THC that impair memory or focus. Choose microdoses, or use CBD-dominant products during the day to stay clear-headed.

Talk to Your Doctor Before Combining Treatments

Even though cannabis and Ozempic don’t directly interact in harmful ways, your personal health situation matters. Always check with a qualified medical cannabis provider if you’re:

• New to cannabis

• Taking insulin or other diabetes medications

• Experiencing frequent side effects from Ozempic

• Unsure which cannabis products are safest for your condition
