......and good day to you @peggioh. Unless you have a dispensary with a "cannabis" pharmacist you are pretty much on your own I think. There are physicians who will approve you for a medical cannabis card based on your symptoms of chronic pain and you can be referred to one of them.

Another way is to talk to a patient customer service person at one of the manufacturers. Or, as I did, receive advice from a nurse friend. These folks can help you know where to start and how to evaluate the results.

This link might be helpful: http://www.projectCBD.org. Just look for the section on dosing.

I use only two products: tinctures (in a bottle with a dropper in mgs) or topicals (in a heavy cream or balm that come in a jar). Edibles and beverages can be quite inconsistent and are really for recreational use. I want to be able to trust the products and know that the company complies with substantial production regulations.

You can start by adding a chosen CBD/THC tincture to a beverage like tea or coffee. Or you just place it on your tongue. Just remember the rule: "you can always have more, you can never have less. You just have to find out how many mg are helpful. You may use half a dropper of a 3:1 CBD/THC product and only a quarter of a dropper for a 1:3 CBD/THC product.

You can learn the basics by reading, You can learn what works for you by doing. Let me know how it goes.
