While the cost of CBD oil products is presently high, it will likely come down dramatically after CBD and hemp are legal by federal standards — but prices will still vary widely. A high price for a CBD product does not always imply high quality, though a low price generally indicates you’re not getting enough CBD to see a benefit, so it’s important to know what to look for when buying or using a product.
Reputable companies selling CBD oil products will state the CBD concentration and extraction methods on the bottle or website. Typically, the concentration is stated as milligrams (mg) of CBD per fluid ounce (though some products standardize mg of CBD to milliliters (ml). The benefit comes from the amount of CBD consumed, not the amount of oil.

To calculate the cost per milligram of CBD, simply divide the dollar amount of the product by the total milligrams of CBD in the bottle. So for instance, a product with 600 mg CBD in a 1 fluid-ounce bottle costing $80 is equal to about 13 cents per mg of CBD; a product with 100 mg of CBD in the same size bottle selling for $40 works out to 40 cents per mg of CBD. In this case, it pays to splurge on the $80 bottle.
As for extraction methods, remember that vapor distillation and CO2 extraction are preferred. These methods yield a full-spectrum CBD product, which will likely be more costly than a CBD isolate because it’s significantly more beneficial. Alcohol extraction is a cheaper method that pulls a more narrow spectrum of plant chemicals and higher levels of chlorophyll, which doesn’t taste great and also takes up space where more CBD could be. Lipid-based extractions will likely fall in the middle price-wise.
The highest quality cannabis is grown indoors, so quality standards can be controlled. Use of clean water and organic methods of farming that are free of pesticide use and unnatural fertilizers are, of course, preferred. With outdoor-farmed cannabis, quality standards and potency are not as easily controlled.
Taste can be a sign of value, too. Poor quality oils will have a very unpleasant chemical taste, and they can cause significant burning to mouth tissues. A good quality product should be smooth and not cause significant burning. Interestingly, the best quality products are associated with a distinct cannabis taste, indicating that the full spectrum of chemical components (with trace levels of THC) are present.
