The answer: With clinical support, not alone, because depression and nicotine withdrawal share the same neurochemical deficit, and managing both simultaneously without support produces a combined burden that unassisted cessation cannot reliably survive.

The mechanism

Nicotine produces dopamine and serotonin on demand. A depressed brain already has a deficit in both. When nicotine stops, the deficit deepens, producing a withdrawal depression layered on top of existing depression that feels like dramatic worsening but is largely temporary neurochemical recalibration.

This is the window where most depressed smokers return to smoking, not because quitting failed, but because the combined neurochemical deficit of the first two weeks is genuinely more intense than either condition produces alone.

What clinical support provides

Bupropion is a cessation medication that is also an antidepressant and was specifically developed for smokers with depression. It addresses both conditions through the same mechanism simultaneously. For depressed smokers, it is the most directly relevant pharmacological option available.

Varenicline is appropriate for most people with depression; the EAGLES trial substantially revised earlier concerns about psychiatric adverse events. Discuss with the prescribing physician.

Continued antidepressant treatment throughout cessation is non-negotiable. Stopping antidepressants simultaneously with nicotine produces compounding neurochemical disruption. Inform the prescribing physician before the quit date, as cessation affects the metabolism of several antidepressants.

What to do differently

Expect the first two to four weeks to be harder than standard cessation descriptions suggest. The withdrawal depression is real, temporary, and not a preview of life without cigarettes.

Exercise is the most important non-pharmacological intervention, producing dopamine and serotonin through the brain’s own mechanisms, directly compensating for the combined deficit. Twenty minutes daily, from day one.

Name what is happening accurately during low moments: “This is withdrawal depression compounding existing depression. It is temporary and neurochemical. It will reduce as recalibration completes.”

The one thing to hold onto

Smoking was not treating your depression. It was relieving the withdrawal that was amplifying it.

The depression on the other side of cessation with proper support is smaller than what you experienced while smoking. That is where this goes.
