Did you know that cocaine detections in Australian workplaces surged by 45.4% in the first quarter of 2026? This sharp rise puts immense pressure on your safety protocols and increases the likelihood of complex workplace disputes. To protect your team and your reputation, you need more than just a positive result; you need defensible drug testing for legal challenges<\/strong> that adheres strictly to the latest Australian standards.<\/p>\n
