03 · What Materia is, and is not

Three commitments.

Clinical, not transactional

A real consultation

45 minutes with a board-certified physician. The visit is conducted the way any specialty consultation would be conducted. If the physician concludes cannabis is not appropriate for you, the physician will say so.

Evidence-led

We follow the literature

The clinical team maintains an internal evidence matrix updated quarterly. Where the evidence is mixed, we say so. Where another therapy has stronger evidence for your condition, we recommend that instead.

Longitudinal, not one-shot

The relationship lasts

The relationship does not end with the issuance of a state card. Quarterly follow-ups. Plan adjustments. Coordination with your primary care physician, oncologist, or pain specialist.
