Workplace Drug Screening
We believe the consumption of Cannabis, in accordance with a medical prescription, should be treated equally with the consumption of any other prescribed medicines.
Here's what should happen
Workplace policies should be developed or amended to reflect the current legal status of Cannabis as a medicine which can be prescribed. Ensure these policies do not contravene current legislation intended to protect employees from discrimination or unfair practices.
Cease using the presence of THC metabolites in a quantitive drug assay sample as the basis for disciplinary action. (The current levels prescribed in AS/NZS 4308:2008 as the maximum allowable limit are so low (50micrograms/Litre) that it is unlikely a medicinal cannabis patient can be expected to provide a negative sample).
Work with Cannabis patients to determine the THC metabolite levels which may be encountered during testing commensurate with their current prescriptions (These levels may vary between individuals and their applicable prescriptions).
Develop a test to determine if a level of impairment exists which may affect workplace safety, based on the type of work to be undertaken.
Ensure the application of policy is consistent across all forms of medicinal products.
