A number of difficulties exist in evaluating published data on CBD or marijuana use for epilepsy. The extremely limited published studies were small, poorly described, and not well designed. Contributing to the difficulty of interpreting published studies, CBD products are not produced under the guidance of good manufacturing practices (GMP) and are not subject to regulations governing labeling, purity, and reliability. In other words, currently, there is no guarantee of consistency between products, or even differing lots produced by the same manufacturer. Without independent testing (e.g. USP certification) of CBD products for content and purity, as well as bioavailability testing of specific products, uncertainty surrounds the use of available CBD products in routine clinical settings.
It also depends on the strength of your CBD. If you’re using max-strength 4000mg CBD from Hemp Bombs, maybe one or two puffs will be all you need. If you’re using a lower strength product, then you’ll have to use significantly more to feel similar effects. Of course, max strength CBD is way more expensive than the lower strength stuff, but it lasts much longer. It’s really a matter of the following question: Do you prefer to spend more upfront or over time?

Rather, what most of these oils appear to be are extracts of the hemp seed. As we mentioned earlier, CBD oil can be made from either hemp or marijuana cannabis plants. No matter which plant they come from, however, they must be made using the flowers, leaves, stem and stalks of the plant, as these are the parts where the CBD compound is actually located.
