Mackenzie Phillips has spoken candidly with striking candour about her battle against substance abuse during the golden years of the acclaimed American television show “One Day at a Time,” exposing the scale of substance abuse that happened both on and off set. The 66-year-old actress, who played rebellious older sister Julie Cooper alongside Valerie Bertinelli, told Fox News Digital that she and her acting partner would take cocaine during lunch breaks and in the dressing room whilst shooting the CBS show, which ran from 1975 to 1984. Though Phillips recognised that Bertinelli has talked candidly about that period herself, she underscored that her own substance abuse problem was considerably worse. Now, many years into her journey of rehabilitation, Phillips is reflecting on those turbulent times with fresh perspective and gratitude for the intervention that finally saved her life.
The Comedy Series Era: Beyond the Glitz
Mackenzie Phillips and Valerie Bertinelli rose to household names as young sisters in their teens on “One Day at a Time,” the cherished CBS sitcom that captivated audiences throughout the latter part of the 1970s and into the 1980s. The two young actresses, close in age, grew up together under the intense scrutiny of Hollywood fame, managing the demands of weekly television production whilst still in their adolescence. Their screen presence together as the defiant Julie Cooper and her younger sister Barbara resonated with viewers, making them cultural icons of the era. Yet behind the scenes of this apparently family-friendly family sitcom lay a far darker reality that neither actress would fully address until many years later.
The friendship formed during those tumultuous years proved exceptionally durable, lasting long after the show concluded in 1984. Phillips has spoken candidly about how her addiction created distance between herself and Bertinelli, testing a bond that had been built on shared experience and mutual affection. Throughout her path to recovery, Phillips repeatedly reached out to her former co-star during stretches of being sober, even driving past Bertinelli’s home to leave voicemails announcing her milestones—six months sober, a year sober—knowing that healing would require patience and persistence. Phillips understood that she had significant repair work ahead, and she approached the reconnection with modesty and resolve.

A Bond Tested and Restored
The friendship between Phillips and Bertinelli, forged in the crucible of early fame, would encounter its most significant challenge during Phillips’s years of active addiction. Whilst Bertinelli managed to maintain control over her dealings with drugs, Phillips descended into a addiction that consumed her life for years. The actress has been remarkably candid about this disparity, acknowledging that she was the one whose addiction became unmanageable. During breaks during filming, the two would engage in drug use together, yet it was Phillips who in the end experienced the repercussions that would transform her life. Bertinelli, understanding the seriousness of her co-star’s fight, had to establish boundaries even as Phillips battled her demons.
What makes their story noteworthy is not the darkness of those years, but rather the resilience of their bond in the aftermath. Phillips has been candid about understanding that she had caused damage that required real restoration, not quick fixes or surface-level apologies. She approached the reconciliation with remarkable patience and grace, accepting that Bertinelli might not be ready to reconnect right away. This mature understanding of accountability became central to Phillips’s recovery narrative. Rather than anticipating immediate forgiveness, she focused on demonstrating sustained change through her actions, progressively rebuilding trust with someone who had seen her at her most vulnerable and destructive.
The Long Journey to Reconciliation
Phillips’s method of reconciliation with Bertinelli reflected a deeper understanding of what genuine amends required. During times when she was sober, she would drive past Bertinelli’s home on Coldwater Canyon and leave voicemails announcing her milestones—six months sober, a year sober—without expecting quick replies. These gestures were not performative; rather, they represented Phillips’s commitment to demonstrating her recovery through consistent action rather than words. She acknowledged that Bertinelli had no obligation to respond right away, and this restraint became a cornerstone of her healing process. By respecting her friend’s boundaries whilst thoughtfully preserving contact, Phillips showed that she understood the gravity of the damage caused by her addiction.
Over a period of time, this steady and considerate approach started producing outcomes. The two women, who had grown up together as adolescents contending with Hollywood’s pressures, in time restored contact as mature women with common experiences and shared appreciation. Phillips has described their enduring bond as founded upon sincere care and appreciation for the people they had worked alongside. The sitcom family they had developed on screen had evolved into real familial bonds off screen, connections durable enough to survive dependency, geographic distance, and years of separation. Their restoration of relations serves as a reflection of the capacity for repairing strained connections when each side undertake the process with truthfulness, perseverance, and dedication to personal development.

Mackenzie Phillips’s path out of addiction to recovery has become far more than a personal redemption story—it has transformed into a purpose of assisting others work through their struggles with substance abuse and mental health. By publicly discussing her experiences on “One Day at a Time” and the turbulent period that followed, Phillips has transformed her pain into a effective resource for advocacy and education. Her willingness to speak candidly about the drugs present on set, her own addiction, and the impact she endured has connected with countless individuals struggling with comparable demons. Rather than hiding from her past, Phillips has chosen to bring it to light, recognising that her story carries significance and truth that can spark real transformation in others.

By recognising both the seriousness of her situation and the possibility of healing, Phillips offers hope to individuals who may feel constrained by their circumstances.

Reframing Her Story
Phillips has begun to see her addiction not as a fundamental shortcoming but as a chapter in a larger narrative of resilience and transformation. Rather than permitting shame to suppress her voice, she has chosen to reclaim her story, discussing candidly the painful facts of her past. This reconceptualisation has been vital to her journey to recovery, permitting her to advance beyond victim status toward a realm of empowerment and meaning. By addressing her cocaine use on set, her struggles with dependency, and the moment she “got caught,” Phillips illustrates that accountability is not about punishment—it is about growth. Her willingness to examine her behaviour with honesty and humour has made her story approachable and compelling to audiences who might otherwise experience disconnection from tales of famous indulgence.
The actress’s approach to reframing her narrative also involves understanding the systemic factors that led to her addiction. Growing up in Hollywood as a child star meant navigating pressures and temptations that most people never encounter. Phillips recognises this context without using it as an excuse, instead understanding how her circumstances formed her vulnerabilities. By examining both personal responsibility and environmental influences, she offers a sophisticated perspective on addiction that moves beyond superficial judgment. This balanced approach has allowed Phillips to become a trusted authority in recovery discussions, someone who grasps that healing requires both individual accountability and understanding of the circumstances that led to damaging conduct.
Resilience as a Daily Practice

Her journey from the height of sitcom stardom to severe substance abuse, and ultimately to lasting sobriety, demonstrates that resilience is not a destination but an perpetual undertaking. Phillips has learned to work through the challenges of her past with dignity, refusing to allow her most difficult times define her future. This dedication to ongoing personal development and honest reflection has become the cornerstone of her success in staying sober whilst rebuilding relationships damaged by years of addiction.
Phillips’s perspective to mental fortitude surpasses her own recuperation to incorporate a wider comprehension of human vulnerability and strength. She acknowledges that substance dependency knows no boundaries, impacting people from varying economic circumstances and accomplishments. By openly discussing her struggles, she makes more acceptable the dialogue concerning substance abuse and mental health, challenging the stigma that often prevents individuals from accessing support. Her fortitude manifests itself not through freedom from difficulty, but through her willingness to face these challenges head-on and relay her journey with people in similar situations. This transparency has positioned her as a powerful role model for people undertaking individual recovery processes, demonstrating that sustained sobriety and meaningful life change are achievable independent of one’s history.
From Casualty to Spokesperson
Mackenzie Phillips’s transformation from victim to voice represents a pivotal shift in how she relates to her own story. Rather than staying confined in the role of someone affected by addiction and circumstance, she has actively reclaimed agency over her narrative. This transition required transcending blame—whether directed at herself or others—and instead prioritising what she could manage in the future. By choosing to speak openly about her experiences, Phillips has channelled her pain into purpose, using her position to teach and encourage others. Her campaigning efforts demonstrates that recovery is not merely about abstaining from substances; it is about building a purposeful existence where one’s experiences, even the most challenging ones, contribute to assisting individuals discover their own way to healing.
As an advocate, Phillips has become instrumental in destigmatising addiction and promoting mental health awareness within entertainment and beyond. She understands that her celebrity status grants her a unique opportunity to reach audiences who might otherwise dismiss recovery narratives as irrelevant to their lives. Through podcast appearances, interviews, and public speaking engagements, she has consistently emphasised that addiction is a disease requiring compassion and professional support, not moral judgment. Her advocacy extends to acknowledging systemic issues within the entertainment industry that enable substance abuse, whilst simultaneously holding individuals accountable for their choices. This balanced approach has established Phillips as a credible, nuanced voice in recovery discussions, someone who speaks from lived experience rather than theoretical knowledge.
