I tried putting CBD in my Bulletproof Coffee (um, on a vessel 200 miles offshore, in international waters) for several days and the CBD caused severe skin dryness and cracking. I normally have very healthy skin.
If you want to supplement with CBD, there are three main challenges: how to get it, how to take it, and how to pay for it.
The other not-so-good: CBD is still illegal in many places
Getting it seems easy. You can find a variety of oral CBD supplements online: pills, lozenges, liquids, and capsules. But check your state laws before you order CBD online. If marijuana isn’t recreationally legal in your state, neither is CBD. And regardless of state laws, you should know that federally, CBD is a Schedule I drug in the United States and a Schedule II drug in Canada. (As of October 18 2018, the purchase and possession of recreational cannabis and CBD became fully legal in Canada).
I’ve been pretty clear about how smoking tobacco or pot is a bad idea because of combustion byproducts, even though nicotine and the active parts of marijuana are useful. When you smoke something, it reaches your brain quickly without passing through your liver. That’s good for CBD – its bioavailability jumps from 6% when eaten to 31% when smoked.  The problem with smoking high-CBD pot (or any pot) is that you inhale all kinds of toxins and carcinogens, as well as THC. Marijuana smoke also contains apigenin, an estrogenic compound that can mess with your hormones, although CBD and THC themselves don’t seem to be estrogenic.  
Studies show that CBD can do some interesting stuff. CBD may:
The main difference between CBD and THC? THC causes euphoria and other mind-altering effects, CBD doesn’t. Not even a little bit. Also, THC is in high quantities in marijuana, and CBD is abundant in hemp.
Don’t smoke it — that wrecks your throat and lungs like cigarettes do. If you’re a newbie, start slow. Some people can have an unpleasant reaction to the vapor.
CBD oil side effects
So, is CBD for you? Only you can decide, and with so many variables, it’s best to bring your functional medicine doctor in on this one. So far, the science says it’s not harmful, it’s not addictive, and it has the potential to have positive effects on a laundry list of ails. But, it’s illegal in a lot of places, for reasons that have little to nothing to do with protecting the public. Biohacking is all about taking the information that’s available to you and making your choices from there.
You can inhale the vapors using a specialized vape pen. This is the fastest acting delivery of CBD, and probably the easiest once you have your pen and cartridge. However, it’s not recommended because vaping comes with a lot of risk.
CBD can cross the skin and go into the bloodstream. A benefit to this method is that you can rub CBD infused oil or salves right onto the affected area.
There are three main ingredients you need to make traditional bulletproof coffee:
Remember: Allow your coffee to cool a bit before adding the orange CBD tincture. You don’t want to scorch it! After about 300 degrees Fahrenheit, cannabinoids start to die.
Here’s where CBD comes in.

How does CBD oil react with coffee, and what are the effects of caffeine combined with CBD?
On a molecular level, caffeine resembles adenosine. Adenosine is a compound that is actually a sedative to the central nervous system and is ultimately beneficial for the regulation of the body’s natural sleep/wake cycle. Drinking a cup of coffee in the morning leads to feeling alert because caffeine blocks adenosine receptors. Instead of actually waking us up, caffeine simply prohibits adenosine from making us fall asleep.
The most important thing to remember when creating these recipes is to remember to have fun with them! These recipes are not an exact science. Everyone has their own favorite flavor profiles, and you can adjust any recipe accordingly.
