I was rx'd the 5mcg Butrans patch yesterday for Endometriosis and chronic low back pain. I don't feel much relief yet but my Dr says it can take about 3 days. After reading a lot about Butrans, it has a lot of warnings regarding avoiding heat. My question is can I exercise and have sex on this without overdosing? Both activities will increase body temperature. Also I have an MMj license, will this interact with the Butrans?
