Companies need to understand marijuana use — and have policies in place now

| Legislation

Contrary to popular belief, marijuana is not yet legal, but it may be soon, workplace responses and, specifically, testing, need to adjust accordingly

There is a common misconception that cannabis has been legalised in SA — but this is not the case just yet.

Judgment is still pending with the Constitutional Court‚ and if legalisation is successful‚ Parliament still has two years to make the necessary changes to the relevant laws. Until then‚ while home users found smoking or in possession of marijuana may attempt to fend off prosecution citing privacy rights‚ instances of public use and being found under the influence of marijuana at the workplace can lead to criminal charges‚ as well as whatever recourse deemed fit by the workplace.

Legality impact

Due to the defendability of home use‚ there is a rise in recreational marijuana smoking impacting how organisations manage and respond to workers under the influence. When‚ and if‚ marijuana use is legalised‚ the substance is likely to be more easily available‚ which will inevitably lead to increased use.

One of the advantages of legalising marijuana is that‚ as it is not considered a "hard drug" and is rarely associated with crime‚ it will undoubtedly free up our police force to focus on more dangerous crimes and substances. Another is that‚ with marijuana considered an illegal substance‚ users put themselves at risk obtaining the substance in shady areas and at the hands of criminals.

Legalisation puts the marijuana business in "clean" hands‚ makes it taxable‚ and — ultimately — safer to use.

On the downside‚ there will be an increase in intoxication‚ which could negatively affect work ability‚ driving ability and — as with alcohol — can lead to an increase in judgment errors.

For now‚ marijuana is still illegal‚ so users may face prosecution based on trace detection in urine tests. But even if recreational use is legalised‚ there will still be regulations surrounding responsible use. Included in this‚ as with alcohol consumption‚ users will not be permitted to work under the influence.

Similar to alcohol‚ marijuana use impacts a person’s ability to think and react clearly‚ thus negatively impacting their ability to properly function at work.

Businesses will need to ensure they are adequately capable of testing for acceptable marijuana levels‚ and of carrying out the necessary disciplinary action should these levels be exceeded. More important‚ with use already on the rise‚ businesses need to be prepared now.

Clear policies

Most organisations should already have clearly defined policies around drug and alcohol use‚ depending on their industry and tolerance approach. However‚ it is likely that these policies currently class marijuana as an illegal drug and‚ therefore‚ it is tested for using a urine test. Unfortunately‚ should marijuana become legal‚ a urine test will not be sufficient.

Alcohol testing is typically done using a breathalyser. Drug testing‚ though‚ is often tested through urine samples‚ which are incredibly accurate at detecting marijuana use. However‚ the active compound in marijuana‚ tetrahydrocannabinol (THC)‚ can linger in a person’s system for weeks — sometimes months for heavy users — which means that‚ even if a person is no longer "high"‚ they can still test positively for marijuana.

With this in mind‚ organisations will need to be able to prove that a user is under the influence to implement disciplinary procedures‚ rather than merely testing for consumption. To do so‚ employers will need a test process that offers a short window of detection.

Where urine tests can pick up traces of marijuana in the system for up to several months post-use‚ a saliva test can more accurately measure if a user if currently under the influence or not. Saliva tests with higher cut off levels for detection will only show a positive result for THC for about six hours post-use‚ rather than six weeks or months. This type of testing will need to form part of organisational drug- and alcohol-testing policies‚ especially where zero-tolerance approaches are adopted.

Taking action

Organisations can still implement the same disciplinary procedures they currently employ for illegal substance use and abuse‚ due to the current illegal status of marijuana. Typically‚ this involves action such as suspension and final warnings or immediate dismissal. At more lenient companies, rehabilitative measures are implemented for first time offences.

With legalisation‚ disciplinary action for marijuana use should follow similar protocols as for alcohol. That is‚ use at the workplace should be strictly forbidden‚ as should working under the influence where the substance still affects the users’ ability to function and perform.
