About three months ago, I added a CBD tincture to the selective serotonin reuptake inhibitor medication I take for depression. My psychopharmacologist told me there was no specific contraindication or reason against taking both, but stressed that there's no data on how the two behave together. There are some known contraindications with other medications, including Warfarin, codeine and oxycodone, but not SSRIs. "It's not that there's no contraindication," Cooper said. "We just don't know."

Cannabidiol can cause sleepiness or drowsiness. Using it along with other herbs and supplements that have the same effect might cause too much sleepiness. Some of these herbs and supplements include calamus, California poppy, catnip, hops, Jamaican dogwood, kava, L-tryptophan, melatonin, sage, SAMe, St. John's wort, sassafras, skullcap, and others.
Some CBD manufacturers have come under government scrutiny for wild, indefensible claims, such that CBD is a cure-all for cancer, which it is not. We need more research but CBD may be prove to be an option for managing anxiety, insomnia, and chronic pain. Without sufficient high-quality evidence in human studies we can’t pinpoint effective doses, and because CBD is currently is mostly available as an unregulated supplement, it’s difficult to know exactly what you are getting. If you decide to try CBD, talk with your doctor — if for no other reason than to make sure it won’t affect other medications you are taking.
If medical marijuana is illegal in a given state, THC levels determine whether a CBD product is illicit or not. In most places, the limit is extremely low. We’re talking under 1 percent THC, with some states opting for a cap as low as 0.3 percent. In this case, the only source that would work is hemp, and CBD products will, therefore, be hemp-derived.
