Some people vape the CBD oil, which is legal everywhere. However, I don't like vaping or smoking anything as I've tried and it hurts my throat and lungs. I have the hunch that it's not good to put anything in my lungs. I smoked 2 packs of cigarettes a day for 17 years and quit cold turkey in 1982. Marijuana helped me quit cigarettes at the time, but I didn't smoke it often due to it being illegal at the time.
I put the CBD oil under my tongue and hold it there for about 30 seconds before swallowing it. It takes longer to have effect then, but it does work. For immediate mild effects, CBD Living Water works immediately.
You're right, insurance won't pay for anything connected to Cannabis. I'm surprised it doesn't pay for your thyroid med. Are you on Medicare? I am, and they pay for my Levothyroxin that I take for my thyroid. It's the generic for Synthroid. Also, perhaps you need an adjustment in the mcg. you are taking. I was being prescribed way too much for several years and had a lot of side effects. My new Endocrinologist cut it nearly in half and had me stop taking it completely for a week or two (can't remember how long). I was worried to learn that overdosing it can cause bone thinning! I don't need that at my age! I hope you get good information from the documentary.
