/\ Not entirely sure what you mean by "refined for medicinal needs" Mike. Pot is ultimately pot and while there are certainly some folks addicted to it just as there (many more) users addicted to alcohol and other substances many, many other people partake in pot for other reasons; to be clear there is no difference between so-called medicinal pot and the pot consumed by recreational users - its the same thing, the only difference are the legal categories of the two but ultimately they are one and the same in terms of composition. They are not however different kinds or strains of cannabis plants.
My buddy about to undergo his second kidney transplant in about 60 days days has used it for over 25 years to combat the extreme nausea felt when his first kidney failed and now again since he started on dialysis as the original second donor kidney fails. Pot is the only thing keeping him from perpetually yacking his guts.
Similarly other folks - Rick Simpson being among the best examples in this country - use if for pain control for such serious issues as cancer. I do edibles purely to assist with mitigating sleep issues due to a lower leg circulatory issue. But I take them only as and when absolutely needed, perhaps 2x/week. Yes they provide a pleasant buzz, especially if I take more than three 25mg gummies, but I very clearly know what my threshold is and I can and do for the most part function without the edibles and am in no way addicted to them.
In terms of smoking the "wrong" weed perhaps that may be the case in terms of something stronger like hash but for the most part unless it is some quite exotic strain, run of the mill pot is pretty benign. I know of several relationships or marriages particularly that have failed due exclusively to booze, but offhand I can't think of any where pot was the root issue.
Like most folks the stories I can relate about people who had very serious personal or family issues with alcohol far, far outweigh the number of instances of the same involving pot. By a very long shot alcohol is the most troublesome, costly and problematic, abused substance in our society.
