Frequently Asked Questions
What conditions can medical cannabis treat?
Medical cannabis is used to manage symptoms of numerous conditions including chronic pain, anxiety, insomnia, depression, PTSD, epilepsy, nausea from chemotherapy, arthritis, migraines, fibromyalgia, multiple sclerosis, and Crohn's disease. The effectiveness varies by condition and individual. Cannabis is not a cure for these conditions but may provide symptomatic relief when other treatments are inadequate.
How do I get a medical cannabis card?
Requirements vary by state but generally involve: (1) being a resident of a state with a medical cannabis program, (2) having a qualifying medical condition, (3) obtaining a written recommendation from a licensed physician, and (4) applying through your state's health department. Many states now offer telemedicine consultations for medical cannabis evaluations. Visit our states guide for specific requirements in your state.
What is the difference between CBD and THC for medical use?
CBD (cannabidiol) and THC (tetrahydrocannabinol) are both cannabinoids but work differently. THC produces psychoactive effects and is effective for pain, nausea, insomnia, and appetite stimulation. CBD is non-psychoactive and is used for anxiety, inflammation, seizures, and as a general wellness supplement. Many medical conditions benefit from a combination of both cannabinoids, and the optimal ratio depends on the specific condition and patient tolerance.
Is medical cannabis safe to use with other medications?
Cannabis can interact with certain medications, particularly those metabolized by the cytochrome P450 enzyme system in the liver. This includes blood thinners, anti-seizure medications, and some antidepressants. CBD in particular can inhibit CYP3A4 and CYP2D6 enzymes, potentially increasing levels of other drugs. Always inform your healthcare provider about cannabis use and consult with a pharmacist familiar with cannabis-drug interactions before combining treatments.
How long does it take for medical cannabis to work?
Onset time depends on the consumption method. Inhalation (smoking or vaporizing) produces effects within 1-5 minutes lasting 2-4 hours. Sublingual tinctures take 15-30 minutes with 4-6 hours of effect. Oral edibles and capsules take 30 minutes to 2 hours to onset but can last 6-8 hours or longer. Topical applications work within 15-45 minutes locally. For chronic conditions, consistent daily use over 2-4 weeks may be needed to achieve optimal therapeutic benefit.
