Having been hippie stoners when we were young my husband and I quit all substances of the sort when we became new in Christ

Over the years life had a way of changing what we intended, especially in the area of physical health. I have awful intestinal issues and migraines among other painful problems, we're not young anymore. I recently began using cannabis for all my maladies. My husband was agreeable at first but is getting more and more hostile about my cannabis use. He is an ex-pastor. We are retired now and I'm beginning to resent his attitude about my medicine when he drinks beer and wine and whatever. He is a master at bible memorization and really knows his stuff, so why does an herb given to us by God bug him so much?
