Still, as the saying goes, absence of evidence isn’t necessarily evidence of absence, and there’s a reason we don’t have a ton of solid research on CBDs yet — “to study it, we need a good source, ” said Ziva Cooper, who is an associate professor at Columbia University and was on the National Academies committee. CBD is hard to get because it’s still technically a Schedule I drug, which limits its availability, Cooper said.
Because of this classification, it's not easy for researchers to get their hands on the drug. "That's not to say you can't do it, but there are hoops you need to jump through that can be a pain, which may deter researchers from going into this space," Bonn-Miller said. "Relatively speaking, it's a small group of people in the U.S. that do research on cannabinoids in humans."
Most CBD oils are available in round-number concentrations such as 250mg, 500mg, and 1,000mg. While these strengths accommodate many CBD users, they may not be sufficient for those with preferences that fall outside round numbers. NuLeaf Naturals offers a less conventional selection of concentrations: 240mg, 725mg, 1,450mg, 2,425mg, and 4,850mg. This range ensures that most users will find a strength that works for them.
The body is able to turn ALA into usable DHA and EPA to some degree, but this isn’t as efficient as getting DHA and EPA directly from food sources that provide it. Even after extensive research, it’s not totally clear how well ALA converts into EPA and DHA or if it has benefits on its own, but health authorities, like those at Harvard Medical School, still consider all sources of omega-3s crucial in the diet.

In a small study published in the journal JCI Insight in 2017, researchers observed that CBD may help prevent stress-related changes in blood pressure. For the study, nine healthy male volunteers took a single dose of either CBD or placebo. Compared to those given the placebo, those treated with CBD had lower blood pressure both before and after experiencing a stressful event.
“[CBD has gotten] very popular because it has effects such as helping with insomnia, helping with pain, helping with anxiety,” Peter Grinspoon, a primary care doctor at Massachusetts General Hospital, said in an interview. “So it just happens to be another one of the hundred or so cannabinoids that are in cannabis, but it’s one that has properties that people find very attractive, so it’s become very popular.”
Nutrition and cooking experts agree that one of the most versatile and healthy oils to cook with and eat is olive oil, as long as it’s extra virgin. “You want an oil that is not refined and overly processed,” says Howard. An “extra virgin” label means that the olive oil is not refined, and therefore of high quality. Extra virgin olive oil contains a large amount of monounsaturated fats and some polyunsaturated fatty acids; many studies have linked it to better heart health. Olive oil has a relatively lower smoke point compared to other oils, so it’s best for low and medium-heat cooking.
According to Ayurveda, fats are used to promote healthy skin, support satiety and calm the nerves. On an Ayurvedic diet, it’s generally recommended to steer clear of trans fats and include plenty of vegetable-based fats and omega-3 fatty acids. Saturated fat is also encouraged in moderation by increasing your intake of foods like ghee, coconut oil and grass-fed beef.
Cannabis sales have been illegal since the 1970 Controlled Substances Act was passed, with the only exceptions being the products made from the "mature stalk" and "sterilized seed" of the hemp plant, which could still be sold since they contained little to no psychoactive components. Even today, federal law has not changed its stance on cannabis. On the state level, however, things have changed dramatically. As of this writing, there are 30 states that have legalized the sale of cannabis in some form, whether that be medicinally or recreationally. Because federal law continues to outlaw the production and sales of cannabis aside from the CBD oil and hemp seed oil from hemp plants, it is illegal for states that have legalized cannabis to sell products across state borders.
