Price Per Milligram (mg): How to determine if you are paying a good price.

When purchasing an oil, whether it is CBD or THC or any other cannabinoid, understanding the price per milligram (mg) is key.  Consider the following example:

  1. Bottle A – 1 ounce of CBD oil, costs $30.
  2. Bottle B – 1 ounce of CBD oil, costs $150.

Looking at that info only, everyone would think purchasing Bottle A is the better deal. Compared to Bottle B, it’s much more affordable.  But is it? Let’s look at it again.  Upon closer inspection..

  1. Bottle A has 100 mgs of CBD.
  2. Bottle B has 1500 mgs of CBD.

So looking at that, Bottle A may be cheaper, but it won’t last very long, or may not even be effective.  If you need a 50 mg dose of CBD, Bottle A has 2 doses (100 mgs/50 mgs per dose = 2 X 50 mg doses in the entire bottle!).  With that same 50 mg dose, Bottle B has 30 doses (1500 mgs/50 mgs per dose = 30 X 50 mg doses).

So Bottle B now seems like the better deal.  To verify that, let’s also calculate the price per mg and compare that as well.

Comparing price per mg is the only way to accurately tell if you are getting a good deal, or if you are being charged too much. To do this, you take the price of the oil/mg of the cannabinoid of interest.  So for Bottle A, $30/100 mgs of CBD= $0.30 per mg of CBD.  Not bad, but let’s do Bottle B too.  For Bottle B, $150/1500 mgs of CBD = $0.10 per mg of CBD.

Conclusion:  Bottle B is actually cheaper than Bottle A when looking at the amount of CBD you are actually getting!  Bottle B turns out to be a much better deal.  It will not only last longer, it is cheaper per mg.

So, for those of you just starting out on this journey, looking at the sticker price is often not a great way to compare oils.  You have to do a little math to determine what the best deals are.  And in my experience, the oils that are priced between $0.05 and $0.10 per mg are actually some of the best quality oils.  These manufacturers set the prices low because they also understand that for medicinal purposes, patients often need larger doses.  Oils that cost more ($0.15 per mg and higher) make long term medicinal use unaffordable for most.

There is one exception and that is when you are looking at a hard to find cannabinoid, like THCa or CBG.  In this case, you are often left to compare the few available options that you can access.

      1. When ordering CBD capsules – I purchased the 25 mg and now just received the 50 mg. The capsules are the same size? Is it how it is processed or should the capsules be larger for 50mg?

        1. you would need to reach out to the company you purchased them from to ask that question. They should have lab reports. If its an oil inside the capsule it could be more of the carrier oil that they added.

    1. The brand Lazarus Naturals was flagged by Evio Labs because it’s sample contained dangerous amounts of lead according to FDA standards.
      “It had four times the amount of lead than is approved. If a child gets their hands on these products, it could be life threatening,” Martinez told the I-Team.
      NBC 4 New York purchased the Lazarus Naturals sample from an independent seller off Groupon. However, Lazarus Naturals said they couldn’t verify that the sample is of their product since they have experienced a problem with counterfeit products sold

  1. Many estimates of potency useing cannabis flower, l can’t find good info on making gummies out of wax distillate..made two batches of gummies, useing 5 grams of wax, and glycerol as binding agent..made 30 gummies, approx two packs of jello and seven pacs of gelatin, can l figure potency of wax to start with, used silicon lce cub trays..for the molds..

  2. Recipe for gummies was two cups of water, 7 paks of unflavored gelatin, and two packs of jolly ranchers green apple jello..and 3 teaspoons of glycerin, as a binding agent, mixed in 5 grams of decarboxilized wax can l figure that potency, molds are silicon lce cube trays..30 gummies…help me figure that one out

  3. Nano sized CBD is 8 x as effective as the oil. So when looking at cost per dose this needs to be taken into account. 1oz oral oil at $30 would be the cost equivalent of $240 of one ounce of nano sized oil.

    1. I have yet to see research done on liposomal or nano CBD showing increased bioavailability. When attending science heavy cannabis conferences, the lack of nano/liposomal/water soluble discussions also seems to point to this being more of a fad than a reality. If you have research, please provide the link. I would love to review it.

    2. I would like to see that citation as well. I have a company that continues to try to sell on a “hydrophilic” cbd tinctures at about .20 per mg claiming that it is much higher absorbtion rate than my Lazuraus Naturals which as noted above costs me .02 per mg with my vet discount (which is very much loved and appreciated by the way! LOVE those guys!)
