That's the bugbear of legalizing it, the expense. Government and pharmacy would have you believe it is very expense yet if you get your own seed, grow your own small plants (you only need a couple), harvest leaves and stems off as it grows to make it grow more and make your own CBD oil it costs nothing more than the price of the seed and a bottle of coconut oil.
I was in dire straits with Tamoxifen and depression and walked like a person 20 years older than myself. I tried pharmacy antidepressants and painkillers but I am drug sensitive now since chemo and my body couldn't take them but I can take a very low dose CBD oil as a supplement to my Tamoxifen.
Government has just taken Codeine off of over the counter meds now so you can't have the old Codral cold and flu med with codeine in it any more. Nor can you get Sudaphed over the counter any more either. Just because a tiny minority abused it to make their own illicit drugs. Way to go gov't penalize the masses yet again for the sins of a few. It is the exact thing they did with marijuana and that didn't work either. Will they ever learn?
