I have used cannabis temporarily to treat a health issue (REM Sleep Behavior Disorder - RBD) and may do so again. If so, it looks like I would need, maybe, 50-300mg of CBD/day. This can get expensive, and I'd like to know how much I'd need to smoke given a CBD-rich strain. I'd like to get at least some by smoking and the remainder by capsule, thinking that a capsule would provide effects that last longer at night. Certainly smoking is a much less precise method, but a general idea would be helpful. My understanding is that THC keeps a person out of REM sleep, which is where RBD happens and is, therefore, very effective. But CBD may quiet damaged or aggravated nerves (my neurological condition: central sleep apnea which causes RBD) also resulting in a cessation of RBD without sacrificing REM and deep sleep, two very, very important sleep stages. Truly, I am ignorant about all of this, and hope that someone might be a little better informed.
