Explore our comprehensive [senior medical cannabis guide](https://cedclinic.com/medical-cannabis-guide/). Physiological Changes: Slower Hepatic Clearance & Orthostatic Risk As the human body ages, several pharmacokinetic shifts occur: - **Reduced Hepatic Blood Flow:** Slower cytochrome P450 enzyme activity extends the duration of oral edibles from 6 hours to over 10 hours. - **Increased Adipose Distribution:** Fat-soluble cannabinoids linger longer in systemic circulation. - **Orthostatic Hypotension Risk:** High THC doses can trigger transient drops in standing blood pressure, increasing fall risk. The Senior Titration Framework: Start Ultra-Low For older adults, clinical titration begins at **0.5 mg to 1 mg THC** balanced with **10-20 mg CBD**. Utilize our interactive [dosing navigator](https://cedclinic.com/medical-cannabis-dosing-and-administration/#ced-dosing-calculator) to calculate customized senior starting points. ## Frequently Asked Questions Is cannabis safe for seniors with heart conditions? Seniors with cardiovascular disease should avoid high-potency THC and rapid inhalation, opting instead for gentle CBD-dominant sublingual tinctures under close physician monitoring. Does cannabis interact with blood thinners or blood pressure medications? Yes. Cannabinoids are metabolized by CYP450 liver enzymes and can alter serum levels of medications like Warfarin. Always review your medication list with a cannabis physician. What is the best delivery method for older adults? Sublingual tinctures with marked milligram droppers or topical transdermal balms offer precise titration and avoid lung irritation.
