It doesn't surprise me that your physician is not a fan of CBD. They are usually under the sway of Big Pharma. My buddy was having prostate issues, as we all do as we age, and his doc found his prostate "slightly"enlarged! And he wanted to prescribe a drug for him. He told the doc that friends of his had advised him that taking "saw palmetto" and drinking cranberry juice could alleviate the condition. The doctor told him that it wouldn't do any harm to do that, but that he was basically paid to write scrips for Big Pharma!
When my buddy told me that I was astounded that the doc would be so honest! So many of them are on the string now, that it's hard to stay free of it!
IMO there are two ways to look at this...
One way is to assume physicians are ignoring alternative or holistic treatments because they are close-minded at best, and dishonest at worst. There are certainly many who are.
Another is that physicians have seen patients suffer as a result of going by claims by those who will profit from selling non-FDA treatments that have zero value. And there are certainly those who do as well. Cannabis is a lucrative business. There are a lot of claims of it helping with a multitude of ailments and to my knowledge, many have yet to be proven.
Not all doctors are dishonest. Some simply put more trust in the peer review and clinical testing processes than they do anecdotal evidence or claims by those who would profit from it.
In the end, no one on the internet knows what's best for others. Either you trust your physician, or you don't. You trust what seems to work for you, or you don't. If the benefits from smoking weed outweighed the negatives, I'd be all over it. But in my world, I've yet to experience that.
