To be clear, there is no one specific test, scan, or anything else of the sort that you can do to determine whether or not you need CBD oil for pain. Also, since cannabis is not yet recognized by the FDA, you unfortunately can’t really go to your doctor either and have them recommend it; until marijuana is FDA-approved, it cannot be prescribed by physicians.
Now that CBD has become so popular, growers are creating strains of the cannabis plant that are optimized for producing high amounts of this particular cannabinoid. There are tons of new strains on the market that feature a high CBD-to-THC ratio. This makes it even easier for the processing facilities to remove the CBD and turn it into an oil extract.
How to vape CBD oil is up to you, but remember that effects are stronger as a concentration of cannabidiol rises. Vaping CBD oil is nothing special and unlike nicotine, users of CBD vape oils work their way up instead of the opposite. Vape oil on itself is safe and there is a lot of scientific evidence that clearly demonstrates that CBD oil for vaping has genuinely nothing to do with getting high.
