If you’re an Ohio patient considering medical marijuana for back pain, you’re not alone. Many people turn to cannabis when traditional treatments like painkillers or physical therapy don’t give lasting relief. But before you start, it’s important to understand both the benefits and the possible side effects.

Common Side Effects of Medical Marijuana

1. Drowsiness or Fatigue

Some patients feel more relaxed — even sleepy — after using marijuana. That’s mainly due to THC, the compound responsible for its psychoactive effects. According to MedlinePlus, from the U.S. National Library of Medicine, marijuana can temporarily slow your reaction time and affect alertness.

💡 Tip: If you’re using marijuana for pain relief during the day, choose low-THC or balanced THC:CBD products and save stronger ones for nighttime.

2. Dizziness or Lightheadedness

THC can cause a mild drop in blood pressure, which may lead to brief dizziness — especially when standing up quickly.

💡 Tip: Stand up slowly, stay hydrated, and give your body time to adjust to new products.

3. Dry Mouth and Red Eyes

THC affects glands that produce saliva and tears, often resulting in dry mouth and slightly red eyes. The National Center for Biotechnology Information notes these effects are harmless and temporary.

💡 Tip: Sip water often and consider moisturizing eye drops if dryness bothers you.

4. Increased Heart Rate

Cannabis can temporarily increase heart rate and blood flow. The American Heart Association’s scientific statement on cannabis and cardiovascular health advises patients with heart conditions to discuss marijuana use with their doctor before starting treatment.

💡 Tip: If you have any cardiovascular issues, opt for CBD-dominant or low-THC products.

5. Anxiety or Paranoia

While many people find marijuana helps with stress and sleep, higher doses of THC can sometimes cause anxiety or paranoia. The Substance Abuse and Mental Health Services Administration (SAMHSA) explains that your experience depends on your dose, product, and tolerance.

💡 Tip: Choose CBD-rich products if you’re new to medical marijuana or prone to anxiety.

Long-Term Considerations

Tolerance and Dependence

Regular use can lead to tolerance, meaning you need more to get the same effect. The National Institute on Drug Abuse (NIDA) notes that while cannabis dependence is possible, it’s relatively mild compared to other substances.

💡 Tip: Take short “tolerance breaks” and use the lowest effective dose to maintain sensitivity.

Respiratory Concerns

Smoking marijuana is not permitted under Ohio law, but vaporized and oral forms are. Even so, any inhaled product can irritate the lungs. The U.S. Food and Drug Administration (FDA) advises patients to use only tested, regulated products from licensed dispensaries to avoid harmful additives.

Balancing Benefits and Risks

For many Ohio patients, the benefits — pain reduction, improved sleep, and lower reliance on opioids — outweigh the side effects when marijuana is used responsibly and under medical guidance.

FAQs

Is medical marijuana safe for chronic back pain?

Generally, yes — when prescribed by a qualified doctor and used in moderation. Most side effects are mild and temporary.

Can I become addicted to marijuana?

Some users develop mild dependence, but serious addiction is rare. Using products with balanced THC and CBD ratios helps reduce this risk.

What if I feel too “high”?

Stay calm, hydrate, rest, and lower your dose next time. Adding CBD can help balance THC’s psychoactive effects.
