possible to remove 99+% of THC, while keeping buds in tact?

Look into the different CBD oil products that are being sold now - legally. I just got a CBD vape juice made by Delta Liquids for my wife who has social anxiety issues. Haven't tried it on her yet but when I take a few hits from hit, it definitely kind of mellows you/reduces anxiety without any real sort of high.

I think the everclear wash would be the easiest way to remove some of the thc. You want to stop getting high but enjoy the ritual & oral fixation of smoking. I think the psych behind replacing the ritual of smoking is where you should be thinking. Plus you save money by not buying buds which you will in turn try to rinse the thc off. Best of luck to you and don't ever stop fighting the depression
