Dear Mama: Rick Simpson Oil

Dear Mama,

I’m a new AZ MMJ cardholder, picked up your new mag at a dispensary that I visited while awaiting my card to arrive. Very nice job. I really enjoyed reading it. It has a nice selection and range of topics.

I’ve gotten the impression that, by law, I can have no more than 2 1/2 oz. at any time. I get that, but also that by some formula, buying concentrates can quickly exceed that limit. Can you enlighten me or point me in a direction that might clarify that for me.

“The highest trade off toward your allotment I could find was 4 grams to 1 gram of Rick Simpson Oil.”

Dear New Card Holder,

First off, welcome to the Arizona cannabis community.  I think you’ll find so many people ready and willing to help you find the best info.  I reached out to my friends in the industry and they shared their knowledge with me on purchase limits and details on how it affects your purchase allowance with the state.

The bottom line is that it varies from shop to shop and from county to county. Quite honestly, each one thinks they are doing it the right way, and that the other shops are not.  But I did some math, so maybe I can clarify a little. The highest trade off toward your allotment I could find was 4 grams to one gram of RSO. With that math you should be able to purchase about 17 grams of RSO every two weeks.  That should be just about what would cover you for a 60 day cancer protocol.

It’s also tricky finding that kind of inventory consistently.  From my conversations, making a connection with one particular dispensary is probably the best route if you need to have that type of consistent quantity for a cancer treatment protocol.  While doing my research, many offered to assist, so there is definitely a community of helpful dispensary personal ready to help meet your needs. It was heartwarming.

Some folks aren’t aware of what RSO is or does.  The letters stand for Rick Simpson Oil. He is an advocate and groundbreaking cannabis icon who treated himself with an extremely concentrated form of cannabis that he developed (quite by chance).  I recommend reading more about his life and breakthroughs in ‘Phoenix Tears, Rick Simpson Oil, Nature’s Answer for Cancer’ by Rick Simpson.

RSO is a very thick, sticky substance.  It can be used in a multitude of ways, but the most medicinal effects are experienced when it is taken sublingually.  It has been reported that there can be up to a 65-75% medicinal benefit from sublingual use versus 25-35% when taken orally or smoked.  You can add it to foods, put a little on top of a bowl, or use it like a dab, but be aware that the medicinal value drops with these options.  

I keep some RSO around to fill the gaps in pain control when my disease process is extra painful.  Pain medications cause me more harm usually than they help, so finding this more natural option has been a game changer for me.   

I try to find an Indica RSO.  Personally, I don’t think it should be made with anything but Indica, as sativa can keep a person alert and is often not helpful for rest and relaxation.  I know lots of people who don’t mind the sativa RSO. If you need to heal, then you need to be still. Indica RSO will definitely help you stay still.

Dosing is different from person to person and also dependent on what you’re using it for, and your current health status.  Cancer treatment protocol is very different from how I would use it for pain control. My tolerance has increased, but the first couple doses can really send a person reeling, so I wouldn’t recommend trying without instructions and a plan to do nothing if it hits you hard.

I’ve read some great reports about using RSO as a topical treatment as well.  I’d recommend mixing it with a little coconut oil, apply it over the area and cover with a bandaid to keep it off your clothes and where it belongs.  Again, I highly recommend doing your own research before using RSO.

Hope this helps, and that wellness is with you too! Mama
