Estimate: Worldwide Population Of Lawful Medical Marijuana Patients

From the International Association for Cannabinoid Medicines IACM-Bulletin of 8 April 2012

Increasing numbers of patients use cannabis for medicinal purposes

An increasing number of patients in the world are using cannabis for therapeutic reasons, with available data from countries, which have installed programs for their citizens. Good data are available for Israel, Canada, the Netherlands and many states of the US with medicinal cannabis laws and registries. In several more countries only a few patients are allowed to use cannabis for medicinal purposes, including Germany, Norway, Finland and Italy. In many other countries such as Spain and some states of the US without a registry such as California the number of medicinal users is estimated to be high, but no detailed data are available.

The numbers in California with hundreds of cannabis dispensaries and clinics that issue medical cannabis recommendations are unclear, since the state does not require residents to register as patients (see below**)

Most of the 16 states that allow the medicinal use of cannabis require a registration. Recently the press agency Associated Press published data on registered patients in different states of the USA based on state agencies responsible for maintaining patient registries:

State: Number of registered patients (per 1,000 of the whole population) –
Colorado: 82,089 (16.3)
Oregon: 57,386 (15.0)
Montana: 14,364 (14.5)
Michigan: 131,483 (13.3)
Hawaii: 11,695 (8.6)
Rhode Island: 4,466 (4.2)
Arizona: 22,037 (3.5)
New Mexico: 4,310 (2.1)
Maine: 2,708 (2.0)
Nevada: 3,388 (1.3)
Vermont: 505 (0.8)
Alaska: 538 (0.8)

Patient registration is mandatory in Delaware, New Jersey and the District of Columbia (Washington D.C.), but their registries are not yet up and running. Washington State has neither voluntary nor mandatory registration.

Data from Israel show that in August 2011 6,000 patients got medicinal cannabis (0.8 patients in 1,000). It is estimated that the number increases to 40,000 in 2016 (5.2 patients in 1,000 citizens).

In Canada 12,116 patients were allowed to use cannabis on 30 September 2011 (0.35 patients in 1,000 citizens).

Numbers of patients using cannabis from the pharmacies in the Netherlands were estimated to be 1,300 in 2010 (0.08 patients in 1,000 citizens). However, many patients in the Netherlands use cannabis from the coffee shops or grow their own.

In Germany about 60 patients are currently allowed to use cannabis for medicinal purposes.

NORML’s Notes:

California NORML published a white paper last May estimating that California has 750,000 – 1,125,000 citizens who possess a physician’s recommendation to use cannabis medicinally.

In New Zealand no patients have been authorised to use cannabis legally. Approximately half a dozen patients have been allowed to use Sativex, a cannabis extract imported from the UK.
