Smoking and Addiction: Understanding Co-occurring Conditions

How Smoking and substance use disorders interact — why they co-occur and integrated treatment approaches.

Smoking and addiction frequently co-occur — each substantially increases the risk for the other, and both must be addressed for lasting recovery.

Why Smoking and Addiction Occur Together

The relationship is bidirectional:

  • Many people use substances to self-medicate smoking, creating dependency
  • Substances temporarily relieve smoking symptoms but ultimately worsen them
  • Addiction itself creates the neurological conditions that drive smoking
  • Shared risk factors (trauma, genetics, stress) predispose to both

The Challenge of Treating Both Smoking and Addiction

Treating only one condition while ignoring the other leads to poor outcomes. Integrated dual-diagnosis treatment addressing both simultaneously is most effective.

Treatment for Co-occurring Smoking and Addiction

Integrated programs address smoking and substance use together through:

  • Trauma-informed therapy (often underlying both)
  • Medication-assisted treatment where appropriate
  • Peer support that understands both conditions
  • Addressing the smoking symptoms that drive substance use
