i smoked for several years.
i've been around...many people who WEREN'T "present", many of whom never did anything other than use marijuana. parents who lived to get high and halfway forgot they had kids...children were well-fed and clothed, but didn't get that physical and mental interaction that is so vital.
i quit before deciding to have a family.
i then raised a step-child who was severely emotionally stilted from her mother's drug use. if ever i would have thought it okay...i sure as heck wouldn't have after taking hailey into my home and life.
personally, i would always feel safer about MJ than a commercial painkiller. MJ has a long history of health benefits & modern pharmaceuticals have a long list of side effects. more power to this mama, i am sure she struggles enough, but i would also caution her to not confide in many people about her treatments.
