The vast majority of CBD oils come in bottles measuring either 15 milliliters (mL), or 0.5 ounces; or 30 mL, or 1 ounce. However, CBD concentration is more important than bottle size. Concentration refers to the ratio of hemp oil solution (measured in mL) compared to the amount of CBD cannabinoid (measured in milligrams, or mg). A 15-mL bottle may contain 100 mg of CBD, 300 mg, 500 mg, or more. The higher the mg amount, the stronger the CBD oil will be. For this reason, the ‘mg’ measurement is also referred to as the oil’s strength; i.e., 400-mg oil might be called 400-strength oil.

A study from 2016 worked with 214 people with epilepsy. The study participants added oral doses of 2 to 5mg of CBD per day to their existing anti-epilepsy medications. The study’s researchers monitored the participants for 12 weeks, recording any negative side effects and checking on the frequency of their seizures. Overall, participants had 36.5 percent fewer seizures per month. However, severe adverse effects were recorded in 12 percent of the participants.

When extracting THC from the cannabis plant, it’s not easy to separate the THC from the mixture. This requires skill, expertise, and technology. Some shady brands create DIY CBD oils by using dangerous solvents, and then try to sell their products online. They sell them at extremely low prices, looking to make a quick buck. Before purchasing, always make sure that the CBD oil you are looking at has no psychoactive effects, and makes sure that it has been extracted with CO2 techniques as this ensures that no dangerous chemical solvents were used. And remember that THC is illegal in most states, so you don’t want to get on the wrong side of the law.
