What actually moves the price
- Size, more than potency. The per-gram cost falls sharply as the quantity rises.
- Indoor versus sun-grown. Indoor costs more to produce. It is not automatically better.
- Extraction method. Solventless rosin costs more because the yield is lower.
- Tax. Cannabis excise and local rates vary considerably by state and municipality.
Why an ounce can look cheaper than a half
Because a median spans every tier on the shelf. A budget sun-grown ounce and a premium indoor half-ounce sit in the same column, and the budget ounce genuinely costs less in total. Compare the per-gram column instead — it normalises the tiers.
Our numbers
The price index publishes the lowest, median, highest and median-per-gram figure for every format and size we carry, computed from the live catalogue and dated. It is our own shelf, not a market survey.
