Wow! Not good news! Medical cannabis has been such a good way to combat pain, anxiety, etc., which lots of us are experiencing. I hope they are continuing do more studies on this. Thanks for sharing this, BklynCatwoman!

Yes, but it's so inconclusive and vague. They're not clear on the amounts and how much is too much. While,my oncologist won't prescribe marinol for insomnia and joint pain, he knows I use a salve made for me by a nurse/friend. I'm still going to use it when I need it but I'm interested to learn more when they have more studies.

I used Marinol to treat nausea when I had a very bad reaction to compazine, but that’s when I was getting chemo for soft tissue sarcoma 7 years ago, and never guessed I would come down with breast cancer years later.

Marinol is a miracle drug in most cases. I hope your current treatment is going well.

Thank you for sharing this and have a great weekend.

Good morning Sister/Warrior Thank you for the article. Every herb and supplement is not for everyone, and they were/are using research studies of high doses of THC marijuana. How much is a high dose. I noticed for triple negative diagnosed women, which I am ,marijuana has no adverse effects. It is always good to check natural supplements/herbs with your medical drugs for adverse reactions, which I have always done for friends and family members. I thank God I don't need to take pharmaceutical drugs at this juncture of my life journey. This research study needs more updated information. I hope there are other researchers also studying this marijuana interaction. i also would like to know who is funding this research?????? Warriors XoXoXoXoXo

I agree. Too many uncertainties but still it was an interesting piece. I'm glad they did the study. I'm not thrilled about having to take Tamoxifen but I'm glad I have the option of taking a drug which drops my chances of recurrence by 50%.

Let’s not forget that drinking alcohol has been noted to increase breast cancer and a variable in cancer returning. Like 30% rate, or something like that. I’m more concerned w that then marijuana.

[BklynCatwoman in reply to Ytabnm]

Valid point. But social alcohol is different. This study isn't about using marijuana to get high but marijuana prescribed for pain or anxiety.

[Ytabnm in reply to BklynCatwoman]

They don’t know the amount of alcohol that can contribute and the same w this article.

[BklynCatwoman in reply to Ytabnm]

American Cancer Society guidelines say no more than 1 drink a day for women plus it isn't recommended during cancer treatment.

[Ytabnm in reply to BklynCatwoman]

Thank you. That’s not very much. Does treatment mean taking Tamoxifen? Or radiation? Chemo?

[BklynCatwoman in reply to Ytabnm]

Here's a link to a thought-provoking, in depth Mother Jones article about alcohol and breast cancer. It basically says that any amount of alcohol is carcinogenic.motherjones.com/politics/20...

[BklynCatwoman]

I think they're referring to any cancer treatment. ACS says that even taking a little alcohol during chemo can have an adverse affect--i.e. can irritate mouth sores caused by chemo drugs. Here's the link to the ACS page on the subject: cancer.org/cancer/cancer-ca...

Thank you for posting this. I have read similar stuff elsewhere - that CBD and THC increases the toxicity and decreases the effectiveness of tamoxifen. I think I found this on the National Cancer Institute website via Cancer Research UK website back in January, but as you rightly say, it doesn't say how much. I mentioned this to my oncologist and she said she'd rather I continue with tamoxifen and take it than to stop. She also said she thought it was large amounts that was the problem but she didn't know for sure because there hasn't been enough testing.

I am interested to know if it is also dangerous for ER+ breast cancer if you're not taking tamoxifen. It seems crazy that more testing hasn't been done. Medical marijuana and CBD is used so much now, if it was a problem you would think there would suddenly be a huge increase in breast cancer diagnoses.
