We knew weed had mad skills when it came to making us feel all groovy, but it turns out it’s so sly that it’s been getting to second base without us even knowing it. According to data from the California Pacific Medical Research Center, that sweet chronic has been getting all up in our breasteses. But it’s a considerate lover. It didn’t just get in there to cop a feel and get out. Instead, it lingered around to try to massage the cancer out.

The CPMRC’s study shows that CBD slows down late-stage breast cancer slows down late-stage breast cancer. Dr. Sean McAllister, one of the head researchers, told Attn:, “We have found [CBD] inhibits key genes involved in tumor progression and metastasis.”

It turns out that tumors get high easily. They have a much higher level of cannabinoids than your average tissue cell, which makes them much more easily influenced by cannabinoids like CBD. Though CBD is potentially effective in treating all cancers, it’s got that magic touch when it comes to cancers that are, like breast cancer, “driven by” particular genes known as Id-1 and Akt.

As is well-documented, one of the most attractive qualities that CBD has as a medicine is that it has virtually no known harmful side effects. “[CBD] has a very low toxicity profile whereas standard cancer treatments are highly toxic,” McAllister said.

However those unfortunately burdened with breast cancer probably won’t be in the clear from using more traditional, and much more lame treatments. McAllister harshed our buzz by adding that, “cannabinoids are most effective when combined with standard first-line agents.” In other words, he thinks you get the most from CBD treatment of breast cancer when it teams forces with chemo and radiation therapies.

That means those using CBD as a treatment might consider a strain or extract-based product with a balance of THC and CBD to get the anti-nausea and appetite-increasing effects of the psychoactive cannabinoid.

One in eight women will develop breast cancer at some point in their life and about one in 1,000 men will as well.  By the end of this year, the U.S. is expected to have 231,840 cases of invasive breast cancer and 60,290 cases of noninvasive breast cancer, so the applications of this study’s findings could be monumental.
