CBD oils may contain some THC. Cannabis may impair your ability to drive safely or operate equipment and may have short- and long-term effects on your memory, attention, mood, heart rate, and mental health. It is also easy to overconsume CBD oil, so it's important to start with a low dose, as it may take several hours or longer to begin to feel the effects after consumption.
CBD oil contains CBD (and often other active compounds) in a carrier oil. There are a number of forms of CBD oil, including softgel capsules, tinctures, and under-the-tongue sprays. Some forms of CBD oil can also be applied directly to the skin, in the form of products like creams and salves. The concentration of CBD varies from product to product.
