As medical cannabis research advances, exciting discoveries are emerging about its potential benefits for cancer patients. Among these breakthroughs, the combination of cannabinol (CBN) and exemestane is showing particular promise for those battling estrogen receptor-positive (ER-positive) breast cancer – the most common form affecting 70-80% of patients.
Understanding the CBN-Exemestane Connection
If you or a loved one is facing ER-positive breast cancer, you may be familiar with aromatase inhibitors like exemestane. These medications block estrogen production to slow tumor growth, but they often come with side effects or treatment resistance.
Here’s where CBN makes a difference. CBN is a non-intoxicating cannabinoid derived from the cannabis plant that shows potential in enhancing exemestane’s effectiveness by:
* Further reducing aromatase gene expression, strengthening exemestane’s estrogen-blocking action
* Regulating hormone receptors to limit alternative tumor growth pathways
* Counteracting exemestane’s weak estrogen-like side effects
A recent study in the European Journal of Pharmacology reported that combining CBN with exemestane significantly slowed cancer cell growth, even at lower doses—suggesting more effective treatment with fewer side effects.
How Medical Cannabis Already Helps Cancer Patients in Arizona
While research on CBN continues, medical marijuana is already improving quality of life for many cancer patients across Arizona. Surveys show that over 40% of breast cancer patients report using cannabis during treatment, with most citing benefits like:
- Pain relief
- Anxiety and stress reduction
- Better sleep
- Appetite stimulation
- Reduced nausea from chemotherapy
A 2024 study found that adding cannabis extracts to anti-nausea medications significantly improved symptom management for chemotherapy patients.

Talking to Your Doctor About Cannabis

If your current physician isn’t familiar with cannabis, you can speak with a specialist at Marijuana Evaluations AZ, who is trained to recommend medical marijuana safely.
