BudMed Bulletin for 5 March 2026

Exciting developments in cannabinoid research this week—highlighting anti-cancer potential, cardiovascular benefits, and long-term safety evidence. Dive in below!

In this issue:

  • CBD + THC deliver POWERFUL blows to ovarian cancer cells!

  • Vitamin D + CBD team up to CRUSH liver cancer cells!

  • Zero evidence cannabis causes brain aging or dementia!

  • Could CBD Be the Heart's New Best Friend?

  • This 4-yr study says inhaled cannabis slashed back pain 66%!

The Journal Oncologie reports: CBD + THC deliver POWERFUL blows to ovarian cancer cells!

  • Both CBD and THC showed strong ability to slow or stop ovarian cancer cells from growing and multiplying (very large reductions in cell survival/viability in the combined data).

  • They work in several ways:Trigger cell death (apoptosis) — making the bad cancer cells kill themselves.

  • Force cancer cells into a resting/stopped phase (G0/G1 cell-cycle arrest) so they can't keep dividing.

  • Greatly increase reactive oxygen species (ROS) — basically creating harmful oxidative stress inside the cancer cells that helps damage and kill them.

This study reports: Vitamin D + CBD team up to CRUSH liver cancer cells!

  • Using Vitamin D + CBD together killed off far more cancer cells than either one alone — the combination was synergistic (they boosted each other's power).

  • The combo needed much lower doses to achieve the same killing effect.

  • It strongly triggered apoptosis (programmed cell suicide) and slowed cancer cell multiplication.

  • In Hep3B cells specifically: The combo stopped cells in the G1 phase (early cell cycle arrest — like putting the brakes on early).

  • It changed genes involved in autophagy (cell self-cleaning/recycling process).

This BMJ Mental Health study reports: Zero evidence cannabis causes brain aging or dementia!

  • Overall, cannabis use didn’t appear to speed up memory loss or increase dementia risk in older adults.

  • Based on these very large groups, there’s no strong sign that using cannabis substantially harms brain aging or contributes to dementia

  • The genetic tests found no evidence that cannabis use actually causes poorer thinking skills or higher dementia risk

This study reports: Could CBD Be the Heart's New Best Friend?

  • CBD and Blood Vessels: When applied directly to arteries, CBD helps them relax, both immediately and over time, facilitating easier blood flow.In experiments with poorly functioning arteries, CBD improves their responsiveness.

  • CBD's Effect on Heart and Blood Pressure: CBD does not alter normal blood pressure or heart rate.It can reduce the heart and blood pressure responses during stress.

  • Protection During Heart Problems: CBD can protect the heart by minimizing damage during heart attacks or when blood flow is restored after blockage. It also mitigates heart complications associated with diabetes.

  • Stroke and Brain Protection: CBD can lessen brain damage during a stroke by aiding in maintaining blood flow.

  • Blood Vessel Leaks: CBD can prevent or reduce leaky blood vessels in:The eyes in diabetic conditions. The brain following inflammation.

  • Cell Health in High Sugar. In high sugar conditions, CBD helps maintain healthier blood vessel cells by reducing cell adhesion and enhancing barrier function.

  • Overall Impact. These effects indicate that CBD might be beneficial for treating various cardiovascular and cerebrovascular conditions.

This study showed: This 4-yr study says inhaled cannabis slashed back pain 66%!

  • Pain and disability improved a lot and stayed better over the 4 years:

  • Average pain score dropped from ~8.1 (very severe) to ~2.7 (mild).

  • Back disability score dropped from ~55% (moderate-severe limitation) to ~37%.

  • Other pain measures (severity and life interference) also fell dramatically (from high 7–8 range down to very low 1–2 range).
