The evidence is growing that pill testing encourages young people to reconsider their drug use—and new forms of testing can provide even more benefits. In 2014, I wrote an article for The Conversation outlining six reasons why Australia should pilot pill testing. Those reasons included:

1. Strong public support for such measures, including among young people

2. Evidence of impact on the black market

3. Impact on consumption choices in a less harmful direction

4. Potential to be used for early warning systems

5. Opportunity to provide education, information, and support to people who may be at risk of harm

6. Data opportunities for improved understanding of the drug market

Four years on, those six reasons still hold today. In fact, we now have stronger evidence regarding the positive impacts of pill testing on young people's drug consumption behavior.

In a study from the UK published just before Christmas, 20% of service users disposed of substances when the drug testing service revealed the substance to be other than what had been intended to be purchased.

Pill testing services at festivals

A further two-thirds of UK festival-goers whose samples did not match their intended purchase disposed of further substances (Measham, 2018). This is the clearest evidence we have of behavior change as a result of pill testing services at festivals. There is no reason to suspect that Australian festival goers are significantly different from UK festival goers.

Indeed, our confidence in the positive impact of pill testing is substantially increased with the first Australian pilot held at the Groovin the Moo festival in Canberra in April 2018 (Makkai et al., 2018).

The independent evaluation revealed that 35% of patrons who had their drug tested indicated that they would change their behavior as a result (including 18% who indicated they would not consume the drug, and 12% who would consume less). There are no reports across any of the services of increases in drug use as a result of pill testing services.

In other research conducted since the original 2014 piece, a survey of Australian festival goers in 2016 (Barratt et al., 2018) revealed that 94% of patrons would use a service if it were available, and would be willing to wait up to an hour for the results (80%).

And data indicate intended users value the importance of the service and are committed to pill testing, with one-third of the respondents willing to provide a whole tablet for testing (Barratt et al., 2018).

Australia is lagging behind other nations. There has been an exponential increase in the number of pill testing services across developed nations in the last five years (Barratt et al., 2018). The opportunity to provide accurate information, including the message that 'no drug is safe' has been a feature of all the pill testing services.

Dissemination goes well beyond the individual service users – 90% of service users at the Groovin the Moo pill testing pilot said they would tell friends of the results. In this way, both the formal test results and the informal network of communications can increase the likelihood that particularly dangerous substances are not consumed.
