If you have ever wondered whether the drinking is causing the mood swings, or the mood swings are driving the drinking, you are asking one of the hardest and most important questions in mental health. With bipolar disorder and substance use, the honest answer is usually that both are true at once, and they keep handing the problem back and forth. The reassuring part is that you do not have to solve that chicken-and-egg question to get better, and you do not have to fix one before the other. They can be treated together.
This guide explains why the two travel together so often, how substances interfere with mood and with treatment, and what real, integrated care looks like — including the outpatient programs available here in Orange County.
Why bipolar disorder and substance use go together
Bipolar disorder is a condition involving distinct shifts in mood, energy, and the ability to function, ranging from manic or hypomanic highs to depressive lows.[1] It is also one of the mental health conditions most likely to occur alongside a substance use disorder. National research describes substance use disorders as commonly co-occurring with mood disorders, including bipolar disorder, far more often than chance would predict.[2]
Several things help explain the overlap:
- Self-medication. During a depressive low, alcohol or other substances can feel like the only way to get any relief. During a high, substances can feel like a way to ride the energy, sharpen it, or come back down to sleep. Either way, using becomes braided into how the episodes are managed.
- Shared biology. Bipolar disorder and substance use disorders both affect brain systems involved in reward, mood, and impulse, and risk for both can run in families.[2]
- Impulsivity during episodes. Mania and hypomania can lower inhibition and raise risk-taking, which makes heavy drinking or drug use during those periods more likely.[1]
None of this means a person is weak or that the situation is hopeless. It means the two conditions are genuinely linked, and the right treatment has to account for both.
Is it the bipolar disorder, or is it the substance use?
This is the question families ask most, and it is a fair one, because substances can imitate the very symptoms doctors look for. Stimulants can produce a wired, sped-up, euphoric state that resembles mania. Alcohol and the crash after stimulants can produce a flattened, hopeless state that resembles depression. Withdrawal can do both. That overlap is exactly why a careful diagnosis matters and why self-diagnosis is so unreliable.
A skilled clinician works to untangle this over time, looking at the pattern: what came first, what happens to mood during stretches of not using, family history, and how symptoms behave across weeks rather than a single bad day. Sometimes a substance is causing the mood symptoms; sometimes an underlying bipolar disorder was there all along and the substance use grew on top of it; very often both are real and both need treatment. The practical point is the same in every case — you do not have to know the answer before getting help, because the assessment is part of the help.
How substances make bipolar disorder harder to manage
Even when a substance starts as relief, it tends to make the underlying condition worse. Heavy alcohol or drug use during a mood episode can intensify the episode, lengthen it, and make it harder to stabilize.[1] A few specific ways this plays out:
- They destabilize mood and sleep. Bipolar disorder is highly sensitive to sleep disruption, and disrupted sleep can help trigger episodes. Alcohol and stimulants both fragment sleep, which can tip mood in either direction.
- They raise the stakes of an episode. Mania already lowers inhibition and judgment. Adding alcohol or drugs on top of that can magnify the impulsivity, the risk-taking, and the danger to a person’s finances, relationships, and safety.[1]
- They complicate medication. Substances can interact with mood-stabilizing and antipsychotic medications and can make side effects harder to read, which is one reason prescribers address substance use directly rather than around it.
This is why “just cut back” rarely works on its own with bipolar disorder. You are not fighting a willpower problem in isolation — you are managing a mood disorder whose episodes the substance keeps reigniting.
Why people stop their medication, and why that matters
One of the most common and painful patterns in co-occurring bipolar disorder is going off medication. It happens for understandable reasons: the medication is working, so a person feels well and concludes they no longer need it; side effects are uncomfortable; or someone wants to drink and knows the two do not mix well, so they quietly stop the pills instead of the alcohol.
The trouble is that mood stabilizers generally work by being taken consistently, and stopping abruptly can let an episode return. When that episode returns, the substance use that the person was using to cope often comes back with it, and the cycle restarts. Breaking this pattern is one of the central jobs of integrated treatment: not lecturing about adherence, but understanding why the medication keeps getting dropped — including the role substances play — and building a plan that holds.
Any change to medication should be made with the prescriber, not on your own. Stopping a mood stabilizer suddenly carries real risk, and only a licensed clinician who knows your history can guide that safely.
Why treating only one side usually fails
Picture treating the bipolar disorder while ignoring the drinking. Continued heavy use keeps reigniting mood episodes and undercuts the medication and therapy, so progress stalls. Now picture the reverse: helping someone stop using while leaving the bipolar disorder untreated. The untreated episodes are still coming, and a returning depression or mania is one of the most common reasons people go back to substances.
This is the core reason modern care treats both at once. SAMHSA and other federal health agencies recommend integrated treatment — both conditions addressed at the same time by one coordinated team, rather than handed back and forth between separate providers who never talk to each other.[3] SAMHSA’s clinical guidance for co-occurring disorders is built around this principle precisely because sequential or siloed care so often leaves the root problem in place.[4]
What integrated treatment actually looks like
There is no single protocol, because good treatment is matched to the person. But for co-occurring bipolar disorder and substance use, an effective plan usually weaves several threads together.
A thorough assessment first. Before anything else, a clinician evaluates the mood pattern, the substance use, your physical health, your history, and your safety — including any current risk during highs or lows.[4] If you have been drinking heavily or using daily, this is also where withdrawal risk is checked. Stopping some substances abruptly can be medically dangerous, so if medical detox is needed, that step comes first. Manifest is an outpatient program and does not provide detox on site, but we coordinate a referral so that step is handled safely before integrated care begins.
Psychiatric care for the mood disorder. Bipolar disorder is typically managed with a combination of medication and therapy over the long term.[1] In integrated care, the prescriber and the therapy team share information, so medication decisions account for the substance use and the substance-use work accounts for the mood symptoms.
Therapy that targets both. Structured approaches help people recognize the early warning signs of an episode, protect sleep and routine, manage triggers and cravings, and respond to high-risk moments without using. Because mood and using are linked for the person, the same sessions can address both rather than splitting them apart.
A safety plan. Bipolar disorder raises the risk of crisis, including suicidal thinking during depressive episodes and dangerous behavior during manic ones.[1] A good plan names warning signs, coping steps, and who to call — and keeps 988 and 911 within reach from the start.
Family involvement. Loved ones often see an episode building before the person does. Bringing family into the plan, with consent, helps everyone respond earlier and with less conflict.
Can this be treated in outpatient care?
For many people, yes. Partial Hospitalization (PHP) and Intensive Outpatient (IOP) programs offer enough structure, psychiatric support, and clinical contact to treat co-occurring bipolar disorder and substance use while you continue living at home and staying connected to work, school, or family. PHP is the more intensive of the two, often a useful starting point or step-down after a hospital stay; IOP offers meaningful structure with fewer hours, frequently as the next step.
Outpatient care is not the right fit for everyone at every moment. Someone in an acute crisis, at imminent risk, or needing medical detox or round-the-clock stabilization should have that level of care first, then often steps into outpatient integrated treatment to keep the progress going. A good assessment is honest about which level fits you right now.
A note for families in Orange County
If you are watching someone you love cycle between highs, lows, and substance use, you are carrying a heavy and confusing load — and you are not imagining the connection between the two. The most helpful thing you can do is encourage an evaluation that looks at both at once, rather than treating the using as a separate problem to fix later. Integrated, same-team care exists for exactly this situation.
Manifest Behavioral Health is an outpatient provider in Laguna Hills serving Orange County, offering PHP, IOP, and virtual IOP for co-occurring mental health and substance use conditions.
