Oregon’s THC Potency Data and Tableau
250,000 THC Potency Test Results From METRC Summarized in a Few Images.
Potency Histogram Series
I based this potency histogram series on the whole number of the test result. These group potency results by frequency. I’ve rounded the potency results to the nearest whole number to make the information more digestible.
2018 Potency
2018 looks pretty normal, actually.
2019 Potency
2019 again looks normal, just with more tests.
2020 Potency
Things are starting to look weird — very strange to see the drop off start to form.
2021 Potency
Oh that doesn’t look good at all, and rather looks like the graph is giving me the finger.
2022 Potency
- I only had half a year’s data for 2022
There’s a bit of skew here — I am excited to see how it resolves.
Year by Year Comparisons
It’s easier to see the malformations in the shapes side-by-side.

If Tableau is your thing, and I highly suggest that you learn to love it, you can find my worksheets around the Oregon METRC Data here. They’re fun to play with and there’s a lot to learn there.
