The cost of smoking cessation rehab varies depending on the program type and facility. Outpatient therapy sessions may range from $100 to $300 each, while intensive outpatient programs (IOPs) or group counseling sessions can cost $500 to $2,000 for several weeks. Inpatient programs, which offer more intensive support, typically range from $10,000 to $30,000 for a 30-day stay. Financial assistance, sliding-scale fees, or insurance coverage may help reduce costs.
