Common Questions from Patients (1-25)

Practice reading and answering these questions aloud. Discuss these with your staff, patients and colleagues. Write and further expand the answers as your knowledge advances.

1. What are the benefits of cannabinoid therapy?

Cannabinoid therapy can offer:

• Pain Relief (e.g., neuropathic, inflammatory)

• Reduced Inflammation (through CB2 receptor modulation)

• Seizure Management in specific epilepsy syndromes (e.g., Dravet syndrome)

• Anxiolytic and Antidepressant Effects (particularly with CBD-rich formulations)

• Appetite Stimulation (beneficial in cancer cachexia, HIV-associated wasting)

• Improved Sleep Quality

2. How does cannabis medicine work?

These effects are mediated by the endocannabinoid system (ECS), which influences pain, mood, immunity, and numerous other physiological processes.

3. Are cannabinoids safe to use?

Under proper medical supervision, cannabinoids are generally well-tolerated. However, they can produce side effects such as:

• Dry Mouth (Xerostomia)

• Dizziness or Drowsiness

• Appetite Changes

Severe reactions (e.g., paranoia, anxiety spikes) are rare and often linked to high-THC products. It is crucial to discuss your full medical history and medication regimen with a qualified provider to reduce risks.

4. Will I get high from cannabinoid therapy?

The “high” is primarily attributable to THC (Tetrahydrocannabinol). However, many medical cannabis products contain CBD (Cannabidiol), which is non- psychoactive and can mitigate some THC-induced psychoactivity. By opting for CBD-dominant or low-THC formulations, patients often experience therapeutic benefits without pronounced intoxication.

5. How do I know what dosage to take?

Dosing is highly individualized, influenced by body weight, medical history, prior cannabis exposure, and product potency. The widely endorsed “start low, go slow” guideline helps identify the minimum effective dose while minimizing side effects. Regular follow-ups with your healthcare provider enable further fine-tuning.

6. Can cannabinoids interact with my current medications?

Yes. Cannabinoids (especially CBD) can inhibit or induce certain cytochrome P450 enzymes in the liver, affecting the metabolism of various drugs (e.g., warfarin, some anticonvulsants). Always disclose all medications and supplements to your healthcare provider to manage potential interactions safely.

7. How long does it take to see results from cannabinoid therapy?

• Inhalation (Smoking/Vaporizing): Relief in minutes, lasting 1–4 hours.

• Sublingual (Tinctures/Sprays): Onset ~15–45 minutes, effects may last 4–6 hours.

• Oral (Capsules/Edibles): Onset ~30–90 minutes, duration 6–8 hours or more.

• Topical (Creams/Balms): Variable onset, usually localized relief within hours.

Consistency in usage is key, as cumulative benefits often manifest over time.

8. Are there different types of cannabinoid therapies available?

Yes. Options include oils, capsules, edibles, vaporized products, sublingual sprays, and topicals. Each has unique onset times, absorption profiles, and durations of action. A healthcare provider can tailor the choice to individual patient needs and preferences.

9. Can children use cannabinoid therapy?

Certain pediatric conditions (notably refractory epilepsy syndromes like Dravet syndrome) may warrant pediatric cannabis formulations (e.g., the FDA-approved medication Epidiolex). Such treatments must be initiated by a specialized healthcare provider, given ongoing research into safety and long-term effects in children.

10. How should I store my cannabinoid medications?

Keep products cool, dry, and shielded from direct light. Oils and tinctures may require refrigeration after opening. Always store out of reach of children and pets to prevent accidental ingestion.

11. What should I do if I experience side effects?

Mild effects (e.g., dry mouth, dizziness) can often be managed by adjusting dosage or changing the route of administration. More serious or persistent side effects (e.g., severe anxiety, palpitations) warrant discontinuation and immediate medical consultation.

12. Is long-term use of cannabinoids safe?

Ongoing studies suggest that, under medical supervision, long-term cannabinoid use can be relatively safe for many patients. Potential risks include dependence (particularly with high-THC regimens), cognitive changes, and mental health concerns in susceptible individuals. Routine monitoring by healthcare professionals is essential.

13. Can I drive or operate machinery while using cannabinoids?

THC, in particular, can impair motor coordination and reaction time. Avoid driving or operating heavy machinery until you fully understand your individual response. Always comply with local laws regarding cannabis use and driving.

14. How do I obtain a recommendation for cannabinoid therapy?

You’ll typically need an evaluation from a licensed healthcare provider familiar with your medical history and local/state regulations. Requirements vary by jurisdiction; some places mandate medical cannabis cards or enrollment in a registry.

15. Are cannabinoid therapies covered by insurance?

Coverage is inconsistent. Some plans may reimburse FDA-approved formulations (e.g., Epidiolex), while many do not cover medical cannabis products. Confirm coverage details with your insurer.

16. Can I use over-the-counter cannabinoid products without a recommendation?

In many regions, non-prescription hemp-derived CBD products are legally available. However, these can vary widely in quality and potency. Consult a healthcare provider before using OTC products to ensure safety and efficacy.

17. What is the difference between THC and CBD?

• THC (Tetrahydrocannabinol): Primary psychoactive compound in cannabis, offering analgesia, appetite stimulation, and euphoria.

• CBD (Cannabidiol): Non-intoxicating molecule known for anti-inflammatory, anxiolytic, and seizure-reducing properties.

Balancing THC and CBD can refine therapeutic outcomes while limiting psychoactivity.

18. Can I switch between different cannabinoid products?

Yes. Patients often adjust products based on symptom relief, side effects, or changes in their condition. Any transition should be guided by a healthcare professional to ensure correct dosing and reduce the risk of adverse reactions or diminished efficacy.

19. What are the signs of cannabinoid overuse or dependence?

• Increased Tolerance (needing higher doses)

• Withdrawal Symptoms (e.g., irritability, insomnia)

• Difficulty Reducing Use despite negative consequences

If dependence is suspected, medical advice should be sought to manage tapering and to explore supportive therapies.

20. Can cannabinoids help with insomnia or sleep disorders?

Many individuals find CBD beneficial for improving sleep quality, while low to moderate doses of THC can also induce sedation. However, heavy or prolonged THC use may alter sleep architecture (reducing REM sleep). A balanced THC:CBD formulation often works best.

21. Are there any dietary or lifestyle considerations when using cannabinoid therapy?

Healthy eating and regular exercise can bolster therapeutic gains. Be mindful if cannabinoids increase appetite, leading to potential weight changes. Avoid combining cannabinoids with alcohol or sedative substances unless cleared by your healthcare provider.

22. How do I track the effectiveness of my cannabinoid therapy?

Maintain a symptom diary, noting dosage, timing, and any improvements or side effects. Share this data with your provider for dosage adjustments and to evaluate therapy success.

23. Can I use cannabinoids alongside other complementary therapies?

Generally, yes. Patients often combine cannabinoids with acupuncture, massage, or herbal supplements. Inform your healthcare provider about all complementary treatments to prevent interactions or overlapping effects.

24. What should I consider when choosing a cannabinoid product?

• Medical Condition (pain, anxiety, epilepsy, etc.)

• Form of Administration (oil, capsule, sublingual, topical, inhalation)

• Product Quality (third-party lab testing)

• THC:CBD Ratio

A knowledgeable provider can guide product selection to align with your therapeutic goals.

25. Are there any myths or misconceptions about cannabinoid therapy I should be aware of, and how can I find a healthcare provider knowledgeable about it?

Common Myths:

• “All cannabinoids cause a high” — CBD does not induce intoxication.
