A clinic is an umbrella term for a group of doctors and healthcare practitioners with a variety of expertise and specialities. Clinics who come on board with us do not need to specialise in medical cannabis but might instead specialise in prescribing for a particular indication, such as pain. We also have independent clinicians prescribing with the project who are not listed here.

When contacting clinics (below), patients are advised to check that their condition can be addressed by that specific clinic. Patients should inform their clinic that they wish to participate in Project Twenty21 before their consultation – it is important that patients make this very clear in order to be able to access Twenty21-subsidised products.

The clinics set their own pricing for the initial and follow-up consultations, and these costs must be covered by the patient.
