How Much Does Medical Marijuana Cost at Ohio Dispensaries?

Prices vary depending on form (processed products typically cost more) and from dispensary to dispensary. To understand what affects price, it is helpful to understand the certification journey medical marijuana must go through in Ohio.


Let’s walk through the structure of the medical marijuana industry:

  1. The production of medical marijuana begins with the cultivators, who are tasked with growing the cannabis plants that produce marijuana.

  2. Next comes the processors, who take the raw material and prepare it into different forms for retail sale.

  3. The medical marijuana processors then sell their products to licensed dispensaries that sell directly to patients.


The dispensaries have the freedom to price their products however they see fit, so some might offer better pricing than others. With this in mind, we've done the legwork to find all of the best prices at Ohio dispensaries throughout the state!

How Much Medical Marijuana Can Be Purchased In Ohio?

One of the most common questions people ask about buying medical marijuana is, “How much can I purchase at the dispensary?” Like many things in this industry, it’s a bit complicated but once you understand the system it is fairly straightforward.


  • Your annual medical marijuana recommendation is broken into 4 (90) day-unit supplies over the course of the year totaling 360 day-units available for purchase. It begins on the day you receive your recommendation.

  • A “day unit” equals a predetermined amount based on what type or form of medical marijuana product is purchased.

    • Example: 2.83 grams of medical marijuana flower equals 1 day unit. Therefore 1 ounce equals ​10 day units. 2.83 x 10 = 28.4 grams or 1 ounce.

  • Each medical marijuana product has a minimum associated “day unit” which when purchased subtracts from your 90 day supply.

Example of the fill periods: Patient is seen, approved, and registered on January 1st 2021.

  1. 90 period January ​1st - April 1st

  2. 90 period April ​2nd - July 1st

  3. 90 period July 2nd ​- September 30th

  4. 90 period October 1st - December 30th

  • In mid April 2020 there was a small but significant change to the way in which the 90 day supply could be purchased. This change splits the 90 day supply into (2) 45 day supplies. 

Here is an example of how it breaks down:

  1. I received my recommendation on January 1st.

  2. At any point between January 1st and February 15th I can purchase up 45 day units worth of medical marijuana in whatever form I like.

  3. For this example we will use marijuana flower. if I purchase a 1 day unit of tier 1 medical marijuana flower, that day unit is equivalent to 2.83 grams of tier 1 marijuana flower. I now have 89 day-units left.

  4. Therefore I can purchase 254.7 grams or 90 days worth of plant material within 90 days.

  5. However due to the restriction of the two 45 day fills you would be permitted to purchase 127.35 grams but must wait for the 46 day to purchase the remainder.

  6. This is to restrict the amount of medical marijuana a patient has access to at one time.

According to the Ohio administrative code, “a patient may purchase no less than a whole day unit at a single time.” The definition of “a whole day unit” varies by form of marijuana.

  • One-tenth of an ounce (two and eighty-three hundredths grams) of plant material;

  • Two-hundred ninety-five milligrams of THC contained in a patch, lotion, cream, or ointment;

  • One hundred ten milligrams of THC contained in an oil, tincture, capsule, or edible for oral administration;

  • Five hundred ninety milligrams of THC contained in oil for vaporization.

Ultimately, each patient can purchase up to a 90-day supply for each 90-day period. With the different forms of medical marijuana being more potent, the 90-day supply for each has been defined as the following:

Tier 1 Plant Material
