Dosing cannabis for pain is difficult. Most people want a dose that takes care of their pain but leaves their mind alone. (Some want to go into couch-lock and completely forget the pain. They will take higher doses.) The general rule is to start with a small dose and slowly raise it until it helps enough with the pain. If you can get your doctor involved, they can be your best guide to determining a dose.
Note that with cannabis more does not need better. Everyone has a sweet spot. As you take smaller doses and move up to your dose, it may feel like every increase is better. But as you go past that dose, additional amounts are often wasted in your system – or can start lessening their effects. Your sweet spot may be 1 mg or 15 mg or 250 mg. You just need to find it.
It is difficult to take too much CBD. CBD dosing ranges from 10 mg to 3000 mg per day. Bowel disease has a recommended 10 mg/day dosage. Cancer pain can call for 600+ mg/day. Poor sleep calls for a 25 mg dose. Anxiety is 300-600 mg. All of these recommendations are on early studies, and researchers are finding different doses and uses frequently.
You should start with a small dose – about 2 mg, and raise that amount until you feel the desired effects. Or until you cannot afford the dose any more. That’s my limit, the cost. I take 5 mg once or twice a day (depending on how long I need to be active). I have a tincture to supplement that amount if it isn’t getting rid of the pain, but I don’t use it often because I cannot afford to.
THC dosing generally falls into a smaller range. Pain treatment can start out at a micro-dose of 1-2 mg. Five to 20 mg/day is a fairly common dose for pain. Recreational uses tend to use 10-15 mg. Be careful going over 20 mg /day because you are very likely to get negative effects. Some people with pain, particularly cancer pain, can go up to 150 mg under a doctor’s supervision.
It is good to start slow with THC. Take two mg and wait. If you don’t feel better in 2-3 hours, take another two mg. Five mg works well for me, in maximizing pain killing effects while minimizing disruption to my thinking. Do not take more than that until you know how it affects you. People take too many edibles when they eat more assuming the dose isn’t working and get in trouble. (Edibles can take 2-3 hours to start working.)
When you are taking CBD and THC together the dose of each will affect the other one. So if you are already taking 25 mg of CBD each day and you add in 10 mg of THC, your CBD needs may stay the same or go down to a lower dose. And the amount it goes down does not have a direct relation to the amount the other rises. Basically, it’s a crap shoot. Most people taking cannabis for pain have to go through a long trial and error period.
There are many more substances contained in cannabis and its extracts. Some of these have given folks great pain relief. People find relief with CBN, CBG, CBA, and THCV.
When you buy cannabis in it’s natural form, dosing can get quite difficult. I would recommend first finding your dose through more measurable types of cannabis – and then doing the conversion over to the actual plant.
When you purchase bud, most sellers have the amount of THC and CBD listed on the product. Some types are high in CBD and low in THC and vice-versa. Different strains can affect your body entirely differently. You can use trial and error for different strains.In the end, you will have to try several strains to get the one that works for you.
The amounts of THC and CBD sellers list are only averages. You could grab a bud that is higher or lower in these components. When used in something like an edible, the amounts of weed may not spread evenly through the food items. You will never get the even dosage with bud that you will get with a tincture or an oil.
Note well: I’m not that kind of a doctor. (I’m a JD / PhD.) Never stepped foot in medical or nursing school. This is not meant as medical advice. It’s just based on my experiences. Always take things to your doctor – and listen to their advice. They may have to adjust your other medications to fit with the cannabis.
