September is Suicide Prevention Awareness Month, and for many Texas families, the timing raises a question they may never have said out loud. Does drinking or drug use make someone more likely to consider suicide? The evidence says the two are connected far more often than most people realize, and understanding that link is often the first step toward getting a loved one the right kind of help.

How Substance Use and Suicide Risk Are Connected

The relationship runs in both directions. Someone struggling with depression, trauma, or unmanaged anxiety may turn to alcohol or drugs to quiet those feelings, at least for a while. At the same time, substance use itself changes brain chemistry in ways that can deepen hopelessness and impulsivity, particularly during withdrawal. Research summarized by the Substance Abuse and Mental Health Services Administration shows just how sharply the risk climbs. Adults with an alcohol use disorder face nearly six times the risk of dying by suicide compared to adults without one. Add a co-occurring drug use disorder and that risk climbs to roughly eight times. Add tobacco dependence on top of both, and it reaches more than eleven times the baseline risk.

Those numbers describe a pattern, and patterns have exceptions. Plenty of people who drink heavily or use drugs never experience suicidal thoughts, and plenty of people with no substance use history do. What the data actually gives a family is a reason to look closer at specific warning signs, covered in the next section.

What Co-Occurring Disorders Look Like Day to Day

A dual diagnosis rarely announces itself. It tends to show up as a person who seems fine most days, then withdraws hard on the ones that go badly. Family members often notice the drinking or drug use first and treat the mood swings as a side effect, when it's frequently the other way around. Nationally, roughly one in four adults living with either a substance use disorder or a mental illness in a given year is living with both at once, according to SAMHSA's most recent national survey data. In practical terms, that means a Texas parent who has been quietly managing a teenager's anxiety for years may be looking at the exact population this statistic describes, without ever hearing the term dual diagnosis from a doctor.

Warning Signs Worth Taking Seriously

A few signals matter more than others, and they're worth naming plainly rather than dancing around.

• Talking about being a burden to others, or about having no reason to keep going, especially paired with an uptick in drinking or drug use.
• Giving away belongings, tying up loose ends, or saying goodbye in ways that feel out of character.
• A sudden calm after a long period of visible distress. This can mean things are improving. It can also mean a decision has already been made, so it deserves attention either way.
• Increasing isolation from friends, church, sports, or whatever community someone used to lean on.

If you notice more than one of these at the same time someone's substance use is escalating, that combination is worth acting on the same day, not the same month. The 988 Suicide and Crisis Lifeline, reachable by call or text, is staffed around the clock and costs nothing to use.

How Treatment Addresses Both Conditions at Once

Treating the substance use and leaving the underlying mental health condition unaddressed rarely holds. Dual diagnosis care is built around the opposite idea: a licensed clinical team evaluates both conditions from day one and treats them together, rather than asking a person to get sober first and deal with the rest later. That might mean medical detox paired with psychiatric evaluation, individual therapy that addresses trauma alongside cravings, and a peer community that understands why the two problems show up together in the first place. More Than Rehab's approach, detailed on our dual diagnosis care page, follows this same integrated model, because Texans dealing with both conditions deserve a plan that doesn't ask them to choose which one to fix first.

Frequently Asked Questions

Does having a substance use disorder mean someone is suicidal?

No. It means the measurable risk is higher than average, which is a reason to watch for the specific warning signs above and to ask direct, calm questions.

What should I do if a family member in Texas is showing both signs?

Start with a direct, calm conversation, and have the number for the 988 Suicide and Crisis Lifeline ready. From there, a same-day call to a treatment center that offers dual diagnosis evaluation is the fastest way to get a professional assessment.

Is it safe to ask someone directly if they're thinking about suicide?

Yes. Research consistently shows that asking does not plant the idea or increase risk. It often brings relief to the person being asked, because someone finally said the word out loud.

Can co-occurring disorders actually be treated together, or does one have to come first?

They can, and most current clinical guidance recommends treating them together. Integrated dual diagnosis programs are built specifically around that approach.
