What is CBD really good for?
There is a lot of hope in the healing powers of CBD. Unfortunately there's way more hype.
- Cannabidiol (CBD) is the most well-known of the 113 cannabinoids found in the cannabis plant.
- There is strong evidence that CBD might help in an array of problems, including anxiety and pain management.
- But numerous companies are marketing low doses of CBD with no proven efficacy and charging a premium.
I began noticing a new beverage in Los Angeles. The first thing you notice is the cheap wrapping, as if directly printed at home and pasted onto the bottle. The sparse print leaves room for plenty of white space. The first six ingredients of one particular flavor are all juice or sugar: blackberry, ginger, blueberry, and lemon juices, along with erythritol (sugar alcohol) and agave. Stevia is featured later on. The final ingredient is the selling point: Hemp CBD.
Each bottle retails for $8.99. Effectively, glorified vitamin water.
Or CBD water, which makes it this year's additive du jour. I've seen this drink sold in the same case as a sugar-rich CBD-infused coffee drink that sells for a dollar less and six fewer ounces. CBD is as trendy as its forebears, antioxidants, keto supplements, and açaí rolled into one, the superfood of superfoods. And you will pay a premium for it.
I've been a marijuana smoker for 25 years, well before I knew about the endocannabinoid system. I was clueless that our central and peripheral nervous systems—and by "our," I mean mammals—were tailor-made to accept cannabinoids (including the most famous, cannabidiol, aka CBD), and that these systems play an essential role in immune system functioning, pain management, and regulation of appetite. I didn't know it for a long time, but I've certainly felt it.
Point being, I'm a fan. Cannabis helped me deal with cancer and chemotherapy, pain management through multiple surgeries, and chronic anxiety disorder. Marijuana helped keep me off Xanax and opioids. Despite that fact that I was among those who nodded and winked when getting my California medical license, I'm skeptical of the hype. The collapsing dominoes that led to legalization have brought with them a gold rush of CBD-infused products and all the ridiculous claims that come along with it.
When Coca Cola is jumping aboard, you know it's going to get weird.
I'm not the only one who's suspicious. As Dan Nosowitz writes at Vox, this trend is the result of two collisions: widespread marijuana legalization and the growing anxiety economy. By 2020, CBD products could reach a billion dollars in sales, making it a potential goldmine for speculators.
There are benefits to CBD, at least according to some reports. As I wrote last month:
Recent research shows a wide range of therapeutic applications, including helping opioid addicts manage pain, helping everyone deal with chronic pain, deal with stress (at low doses), ease pain associated with multiple sclerosis, and may even, somewhat counterintuitively, help combat the obesity epidemic.
Yet CBD is enforced as a supplement, as unregulated by the FDA as most homeopathic products and "natural remedies" that make up a lion's share of the $49 billion herbal supplement industry. According to Nosowitz, the FDA actually regulates CBD as an active ingredient, meaning you shouldn't be able to just throw it into a cup of coffee and double the price, but what sort of regulations are any federal agency even enforcing these days? Nosowitz continues:
CBD is about as poorly regulated and understood as a product this popular can possibly be. It's not accurate to say that CBD, as a whole, is bullshit. From a medical perspective, it's promising; recreationally, it's interesting. But that doesn't mean the stuff you're buying works.

The burgeoning CBD oil industry, for example, faces a serious problem: science. Not that that stops any holistic company. Topical application or ingestion of CBD are much less effective means than inhaling. Sipping it from your hyped-up vitamin water means most of the CBD will just bind to other fat in your body and never reach your brain. Smoking, as Nosowitz writes, "bypasses the digestive system."
Even then, he was only able to discover one study detailing the bioavailability of inhaled CBD and none on topical lotions. Even more problematic is dosage. One study discovered that the only amount of CBD that made a noticeable difference in anxiety levels was 300 mg. The standard dose in most products is 20 mg. One coffee shop Nosowitz highlights adds 5 mg to their $9 coffee. So really, you just paid $9 for… coffee.
More studies are being conducted on CBD and, hopefully, the 112 other cannabinoids found in the marijuana plant. Legalization and destigmatization will hasten that process. We should welcome this progress so that we can separate the wheat from the chaff—the flower from the stem—and make smart decisions about how to apply this plant medicine. Then we can stand on firmer ground when denouncing market manipulators bucking a trend and put our money into products that work as intended.
In my refrigerator sits a $42 bottle of CBD oil we bought for our cats when we were integrating our newest member with our overly territorial Maine Coon. At 300 mg per bottle, it would have taken the lion's share to quell any anxiety—cats being smaller than humans would likely not require the same dose. Still, the recommended dose did nothing to stop their anxiety.
Something else did: Prozac. It's not a long-term strategy (as such anti-anxiety medications were never designed to be). Over a three-month period it's worked wonders; we're now tapering them off. That's the thing about clinical studies: sometimes they're effective. It's a message I hope CBD hucksters take the time to learn.
We know the dangers of too little sleep. Now for the other side of the story.
- Western University researchers found that sleeping over eight hours per night results in cognitive decline.
- Oversleepers suffer similar difficulties on certain cognitive tests as those who sleep under seven hours.
- Not all the news is bad: one night of oversleeping results in a cognitive boost.
The comics titan worked for more than half a century to revolutionize and add nuance to the comics industry, and he built a vast community of fans along the way.
- Lee died shortly after being rushed to an L.A. hospital. He had been struggling with multiple illnesses over the past year, reports indicate.
- Since the 1950s, Lee has been one of the most influential figures in comics, helping to popularize heroes that expressed a level of nuance and self-doubt previously unseen in the industry.
- Lee, who's later years were marked by some financial and legal tumult, is survived by his daughter, Joan Celia "J.C." Lee.
The government hopes to see 1.5 million electric cars on roads by 2030.
- The legislation is expected to pass by the end of 2018.
- The move is inspired partly by Israel's recent discovery of several large deposits of natural gas.
- It's one of the latest developments in Israel's broader plan to wean itself off other more destructive fossil fuels.
The results come from a 15-year study that used ultrasound scans to track blood vessels in middle-aged adults starting in 2002.
- The study measured the stiffness of blood vessels in middle-aged patients over time.
- Stiff blood vessels can lead to the destruction of delicate blood vessels in the brain, which can contribute to cognitive decline.
- The scans could someday become a widely used tool to identify people at high risk of developing dementia and Alzheimer's.
