ASP Hazel Chua is a Manager at the Planning & Development unit of the Communications Division at the Central Narcotics Bureau. She holds a Bachelor of Social Science with Merit in Psychology. Prior to this posting, she held the position of Specialist Investigator and was also an Enforcement Officer.
Since its establishment in 1971, the Central Narcotics Bureau (CNB) has been at the helm of Singapore’s battle against drugs. CNB offers passionate individuals the opportunity to explore a variety of roles, gain multifaceted exposure while keeping Singapore drug-free amidst the changing global and regional drug situation.
ASP Hazel Chua’s career is a testament to this. Having taken on various roles from Enforcement Officer to Investigation Officer, her latest posting to CNB’s Communications Division as Manager, Planning & Development allows her to design and implement inspiring campaigns. Her career path exemplifies CNB’s investment in fostering well-rounded officers who excel as enforcers, educators and engagers—the core 3 E’s in our fight against drugs.
We caught up with Hazel to learn about her impactful journey at CNB.
What made you consider joining CNB?
Honestly, I never set out to be a law enforcer. I didn’t know exactly what I wanted to do, but I knew I didn’t want a mundane 9-to-5 office job. I wanted a meaningful role that would allow me to interact with and help people. When I stumbled upon a job opening at CNB on Careers@Gov, I thought, “Why not give it a shot?” I had nothing to lose, and that decision has led me to where I am today!
What do you actually do as a CNB officer?
It’s been an awesome eight-year journey with CNB! I started out with foundation postings as an Enforcement Officer and later, an Investigation Officer. These roles equipped me with the core skills that CNB officers require to conduct ground operations and investigations. I was involved in high-stakes operations, which included effecting forced entries when suspects refused to heed the lawful orders of officers, and dealt with suspects who attempted to evade arrest. As a foundation officer at CNB’s Enforcement Division, I could observe my seasoned colleagues manage dynamic situations during anti-drug operations.
As an Investigation Officer, I could hone deeper insights into investigative techniques and our judicial and criminal systems. This knowledge base proved invaluable as I progressed to take on complex drug trafficking investigations as a Specialist Investigator. I was given the opportunity to work on complex evidence analysis and detailed analysis work. Memorable cases that I investigated included a case involving drug trafficking via a drone, drugs concealed in fruits and an arrest with drugs as well as huge sums of cash.
I’m presently assigned to CNB’s Communications Division. My work here extends far beyond media interaction—we focus on preventive drug education and other initiatives to raise public awareness about the dangers of drugs. I get to collaborate with government agencies, private organisations, and youth groups to support initiatives for DrugFreeSG.
In 2023, I was involved in work supporting the Inter-Ministry Committee on Drug Prevention for Youths (IMC), a Whole-of-Government initiative to address the youth drug situation. It’s been a great opportunity to work with different agencies to push out anti-drug messages to a wider audience.
Is communications work impactful?
I’ve organised various anti-drug programmes and public awareness campaigns. One of the most notable initiatives was the annual DrugFreeSG Video Competition. This competition engages youths who are passionate about video production, giving them a platform to creatively express their understanding of the harms of drugs through storytelling. It’s always heartening to see students put in the effort to contribute towards keeping Singapore safe by raising awareness amongst their peers.
While we’re focused on reaching as many people as possible, the true measure of impact lies in shifting mindsets. I am heartened that feedback about our initiatives has been incredibly positive, with many participants expressing strong alignment with Singapore’s anti-drug stance. This is a direct encouragement for me about the impact of my contributions towards preventive drug education and building community involvement towards Singapore’s vision of a drug-free society.
What would you say is your biggest career achievement?
I would never have imagined the opportunity to organise the inaugural Drug Victims Remembrance Day in 2024. This groundbreaking initiative was introduced to all public schools, highlighting the devastating impact of drugs, not just on the abusers but also on their families and communities.
Organising the event has challenged me to be innovative in how I balance creating awareness with sensitivity as we shift the focus to the lesser-known victims of drugs—family members and others in the community. Laying the foundation through the first observance of the Drug Victims Remembrance Day in May 2024 has been deeply fulfilling. Apart from ground operations and investigating traffickers, I know I am also contributing towards a lasting impact on Singapore’s anti-drug efforts through the shaping of attitudes, fostering of empathy and deeper engagement with our community.

That’s inspiring! Tell us three standout aspects about the work culture at CNB.
Collaborative and Supportive: CNB’s work culture is built on teamwork and a shared purpose. Whether it’s operations, campaigns, or other types of work, we always have each other’s backs in #TeamCNB!
Resilient and Resourceful: The fight against drugs is tough and long-drawn operations can be physically and mentally taxing, but resilience defines CNB and our teams. We adapt to evolving drug trends, criminal tactics, and generational shifts in mindsets with a ‘never say die’ attitude that I deeply respect in all my CNB colleagues.
Values Achievement and Well-being: This encapsulates our approach towards balancing intense anti-drug efforts with necessary breaks so that our teams can come back even stronger. CNB’s work demands high levels of commitment and we go all out to achieve it. However, we also know how to unwind when the job is done!
Being a young mom and excelling in a uniformed career is no easy feat! How do you handle these responsibilities?
I look forward to picking up my little ones from childcare every evening. This is possible only with support from my supportive bosses, who value work-life balance and trust me in my abilities to deliver high-quality work.
I also choose to make time for self-care. For instance, I fit in my runs during my lunch hour. This way, I get some “me-time”, stay fit for my role, and it also energises me to do what I need to get done! There will be challenging workdays and I’m ever grateful to my supportive husband and family who help me navigate this delicate balancing act. My family and CNB’s supportive work environment allow me to give my best to both my career goals and my family.
What advice would you give to our readers who are considering a career at CNB?
If you’re considering a career at CNB, don’t be deterred by what seem like impossible physical demands. Our structured and rigorous training will prepare you for the job. For young women concerned about career progression and family planning, balancing both is possible given our supportive work environment and understanding leaders.
Do keep an open mind and be willing to step outside your comfort zone. Joining CNB isn’t just about fighting drug crime—it’s about being part of a larger team effort to protect our community, our families, and support those affected by drug abuse. The work is challenging but incredibly rewarding!
