How to Assess Your Child’s Substance Use Without Over- or Under-Reacting

If you are a parent trying to figure out how serious your child's substance use really is, you are making one of the most consequential assessments of your life without a reliable framework. In this solo episode, Brenda Zane borrows a powerful concept from medicine, staging, to give parents the clarity they have never been handed. The result is a four-stage map that helps you stop reacting to incidents and start responding strategically. Why parents have been navigating without a map Medicine has long used staging to give patients and families a shared language for urgency and appropriate response. Parents of children who use substances have received nothing comparable. As Brenda puts it, parents are expected to assess a situation that clinicians in other fields spend years learning to read. This episode is an attempt to close that gap by borrowing the staging concept, not because addiction is like cancer, but because staging is one of the most useful ideas medicine ever produced. Two things that change everything about today's substances Before walking through the four stages, Brenda sets the landscape with two facts that are categorically different from twenty years ago. First, substances themselves have changed. THC concentration in cannabis averaged around 2% in the 1960s and today commonly exceeds 12% in flower, with concentrates reaching 60 to 90 percent THC. Second, fentanyl contamination of the street drug supply is now essentially complete. 'If your frame of reference is, my kid is just experimenting like I did, you're comparing two completely different chemical realities. Even moderate use of today's THC or something that has fentanyl in it carries huge risk that even the use of 10 years ago does not compare to.' — Brenda Zane Brenda also flags a dangerous and counterintuitive pattern: the young person who is quietly at home, withdrawn, self-medicating anxiety and depression in their room. The absence of a visible crisis is not evidence of an absence of a problem. The four stages of substance use Drawing on the DSM-5 spectrum of mild, moderate, and severe substance use disorder, Brenda maps four stages parents can actually use. Stage 1: Experimentation and early use. Social, curiosity-driven use at parties. The brain's reward system is being introduced to artificial dopamine spikes, but most people who try substances do not develop a disorder. The appropriate response is connection-based conversation, not panic, not silence. Stage 2: Regular use and developing pattern. More frequent, more intentional use; sometimes alone. Mood shifts, changing friend groups, disrupted sleep, withdrawal to a room. Tolerance is building. This is the stage where parental approach matters most, because influence is still significant and CRAFT-based skills can alter the trajectory. Stage 3: Problematic use and moderate to severe SUD. Substance use is now organizing your child's life. They may be using just to feel normal, not to feel good. Professional support is no longer optional. As Dr. Gabor Maté frames it, the question is never why the addiction but why the pain. Stage 4: Severe SUD and crisis. Medical risk is real. Overdose, withdrawal complications, complete breakdown of functioning. Safety comes first, but the relationship is not abandoned. The critical difference between cancer and addiction staging Unlike cancer staging, which is largely linear, addiction staging is not. People move in both directions. Early and long-term recovery are real: SAMHSA data shows 72% of Americans who have ever had a substance use disorder are in recovery. This is also the stage where the cancer comparison earns its keep: the intensity of the response must match the reality of the situation. '94% of the time, they don't believe they have a problem, or they don't know, or they're too ashamed, or they just think that they don't need help yet. So this is where your role as a parent becomes very important, uniquely important, because you, my friend, are the biggest and most influential factor in your child's willingness and ability to get help.' — Brenda Zane How to use this framework right now Brenda walks through a practical assessment process: look at observable markers, not just at the substance itself or the absence of obvious crisis. Track functioning, frequency, consequences, secrecy, isolation, and mental health. Map communication strategy to the stage your child is actually in, not the stage you hope or fear they are in. And do not wait for a crisis to get your own support. The stream community, one-on-one coaching, and a personal therapist are not luxuries at this point. They are the infrastructure that keeps a parent ready to move when the window of opportunity opens.
