Scam CBD sellers tend to manufacture low-grade oils via ethanol (or other solvent-based) extraction, in what is little better than trying to do it yourself in your basement. The result is a liquid that contains a little CBD (along with some other cannabinoids and terpenes), but not in the quantities needed to be effective in terms of any legitimate medicinal function. Moreover, these solvent-based extracts can contain unnecessary and potentially harmful components — after all, scam artists are not going to reveal the REAL ingredients, are they?
Yes, CBD derived from hemp plants is legal in the U.S. Growing, processing, and selling hemp and hemp-derived products for commercial purposes in the United States is permitted. While previously hemp was only legal to grow for hemp pilot programs and research needs, the passage of the 2018 bill reclassified hemp as an agricultural commodity and made it legal to produce all hemp-derived products, including CBD oil.
These products contain high levels of essential fatty acids (EFAs) including linoleic acid, omega-6, alpha-linolenic acid, omega 3, gamma-lineolic acid omega-6, stearidonic acid, and omega-3. Just 15ml per day of hemp oil (derived from hemp seeds) provides the entire daily human requirement of essential fatty acids. Hemp seed oil provides 9kcal/g and it is very low in saturated fatty acids. Hemp seeds contain all 20 amino acids including 9 essential amino acids that our bodies do not produce themselves. These amino acids are believed to improve muscle control and normal body maintenance of cells, muscles, tissues and organs.
I have read about studies from Europe (not very specific I know) that suggest CBD might work better for some people if combined with some level of THC. Also, the getting high part can be helpful, although not for everybody, of course. A second point – I don’t hear very much about CBD eliminating or almost eliminating pain for people with severe pain. Helpful, but, so far at least, it doesn’t seem that CBDs can replace opioids or substantially reduce pain for all chronic pain patients. Maybe someday.
