In the past years, being in the cannabis packaging industry, we’ve seen more changes for marijuana packaging requirements in different states in the US and Canada.
This post is intended to list some “Universal symbols” applied in the packaging, which most cannabis brands should consider when designing their packaging.
These THC warning labels ensure that customers are informed about what they are purchasing and helps to prevent unintended use.
We will list the existing cannabis “universal symbol” in this post and the universal symbol download link. Also, some required statements need to apply to the packaging.
All the information in this post is general information only, not constitute legal advice.
The information provided below would be subject to change if there is any update.
Now let’s dive right in.

7 Michigan
Universal Symbol:
Michigan Cannabis Universal Symbol
Quick Fact:
Most of the United States spells marijuana. But if you live in the state of Michigan, you may have noticed some official documents spelling it like “marihuana.”
When Michigan began passing laws related to cannabis, they continued using the “marihuana” spelling since it was technically the official spelling used by the United States government.
And since every previous marijuana law used the “h” spelling, the state simply continued to do so as well.
While official documents and licenses contain the “H” spelling, cannabis businesses aren’t required to do so and are free to use both.
