My wife and I were told by a physician that you need both to be effective. It's like how vitamin c needs magnesium to be effective.
We were told the same thing. My husband take 1-1 ratio of CBD-THC, the recommended dosage is all over the map. From 1 gram per day of RSO or FECO, to much higher and lower amounts. The real mystery is dosage getting it from a reliable source. Too much conflict of interests still messing things up to get a clear idea of dosage.
We've been using 1:1 ratio in various cancers, but when patients come in acting high I can tell there THC ratio is higher
