I think there needs to be some recognition of the differences between CBD and cannabis. They're not the same, aren't used for the same purposes (mostly unless medicinal), not even prepared the same in manufacturing. I do think in fairness to members here their discussions of CBD should be recognized as different than recreational cannabis use.
Let's face it, whether you have a few beers when you get home at the end of a day or a joint is a personal choice, and the joint does have fewer health risks over time. But those who use CBD are almost always using it in some medicinal way whether it's pain, insomnia, anxiety, depression, or assorted and sundry, but do not get high from it. Which is also why it's legal at this time.
My biggest concern with CBD is you never really know what you're buying. There was a story within the last 6 months (sorry, no reference to give) that found the amount of CBD in a product labeled as x mg (the gummies seem a common problem) found 90% of products tested did not have the strengths listed on the products, and a few had no detectable. In an unregulated market, and CBD seems to fall into that "vitamin" category which has no real oversight unless complaints are filed against it with the FTC or FDA. I know how we all feel about regulatory stuff regarding the FDA, but the free market doesn't work super well at correcting these problems when the consumers have little to no ability to check the validity of a product's basic claims, not even does it work, just how much are you really buying with your money (multiple herbal products like those at GNC have in the past been noted to present the same issue for consumers).
Of course now with cannabis that problem is even greater as there is no one to turn to when adulterated products are discovered. It's not like the FDA regulates them, so it would fall to the DEA, but they're staying clear for now of enforcement in states that have gone the legalization route. So what remains is for states to either enforce on a local level where legal and take action against the black market, but many of those same states (and others that don't even have legal recreational use) and cities have decriminalized use and possession, so local law enforcement has even less ability to intervene other than going after the larger black market distributors. And after 50 years of "the war of drugs" we know how useless that is.
