Everyone wants a piece of CBD, and nobody is watching. Remember: There’s no regulation by the FDA or anyone else. An investigation by Natural Products Insider, a trade publication for the supplement industry, revealed that CBD producers are, at best, claiming to follow “good manufacturing practices” without any official oversight. It’s illegal to sell something that isn’t what its packaging claims it is — that falls under the purview of the Federal Trade Commission — but nobody is doing onsite testing.
That said, both Blessing and Carson warn that CBD should still be considered a drug, which means it can interact with other drugs. “CBD does interact with drugs that people are taking,” says Blessing. “So if you’re taking an opioid cough suppressant, or you’re taking serotonin-based medicine, like an SSRI, you can have strong drug interactions.” While most coffee shops are likely using doses too low to cause such interactions, Blessing says it’s something to be aware of. “If a coffee shop happened to have a way of making a product with a lot of CBD in it, then that could really interact with the medication this person is taking, and the effects they think are due to CBD could partly be due to that medication interaction,” she says.
Ian Ford, owner of Caffeine Underground, prepared my order as if it were any other latte (CBD-infused drip, mochas, and cappuccinos are also available), except he included a healthy amount of the CBD-infused coffee with the regular blend. Once I got my drink, I sat down at one of the tables. It was just before noon on a weekday, and the coffee shop was mostly empty, except for a few people working on laptops.
Another area where the healing effects of CBD are impressive is it’s ability to treat cancer. Unlike chemotherapy or radiation therapies, which destroy not only cancer cells but surrounding healthy cells, CBD effectively chooses cancer cells and gets them to commit suicide. This process is called apoptosis and it is a part of the body’s natural growth cycle. Cancerous cells are immune to this process, except with the intervention of CBD.
Recent testing of cannabis products from Los Angeles marijuana dispensaries showed over 90% of tested products to contain HIGHER than normal contaminants and pesticide levels, despite organic claims. (The USDA National Organic Program does not certify organic claims on marijuana, and it’s actually not a legally permitted claim on these products.- FYI, I’m an certified IOIA, Independent Organic Inspectors Association organic processing inspector.) There’s no intrinsic difference between high-THC cannabis and low-THC cannabis that somehow renders one clean and one heavy with contaminants. As with every other crop, it is a matter of soil conditions, growing conditions and horticultural inputs. 
In the current market space is there much difference in cost, in bulk, between 99+% pure CBD from the different sources being discussed? IOW between high-cbd cannabis, and low-total-cannabinoid “industrial hemp”, and hemp grown for seeds not fiber? Extraction from high-cbd cannabis would seem easier as you have to work with less plant material per unit of end product, but then it costs a lot less per lb plant material to grow a huge field of hemp. So, how does it land these days?
