DHA launches new smoking cessation clinic DUBAI, January 11, 2021 Dubai Health Authority (DHA) added a new Smoking Cessation Clinic in Nad Al Hamr Health Centre, totalling the number of DHA Smoking Cessation Clinics to three. The DHA smoking cessation clinics, which cater to around 400 customers annually, recorded a 14 per cent quitting rate in 2020. Globally the quitting rate is in the range of 10 to 20 per cent. DHA’s Primary Health Care Sector established the first Smoking Cessation Clinic in 2010 after studies found that professional support and approved cessation medications can more than double a tobacco user's chance of successful quitting. Studies also found that without cessation support only four per cent of attempts to quit tobacco will succeed.
