I bought the THC Sativa as well as the 1:1 CBD/THC as part of my cancer therapy. I found it difficult to function during the day after ingesting THC and CBD therapeutic amounts until I could build up a tolerance. The transdermal patches give me an even distribution of cannabinoids so I can perform daily activities more normally. The Sativa patches do not make me as tired as Indica. I am taking heavy doses of RSO and high grade CBD oil as well as suppositories so it is a rigorous regimen. I highly recommend the patches because of the consistency of delivery. Green Door has been so professional as well as friendly and kind. Delivery is prompt and hassle free. As an aside ... I have had a remarkable reduction of tumors in just 8 weeks combining the cannabis treatment with chemo. The word "remarkable" came from my oncologist who has no idea I am also using the cannabis treatment. It's working and there will be no more chemo for me.
