A fact-checked cannabis encyclopedia

What everyone says about cannabis is mostly wrong.
So we check the claims that matter.

Every article is sourced, evidence-labeled, and reviewed for unsupported claims, weak science, disputed lineage, and cannabis marketing folklore.

Our promise

Every claim is labeled strong evidence, weak evidence, or anecdote — because the difference matters.

If the science is murky, we say so. If a strain's lineage is disputed, we show the dispute. If a "fact" everyone repeats turns out to be marketing, we name it.

Each page goes through a structured fact-check pass and stays open to correction as laws, research, and product claims change. No black boxes.
