A study by The University College London (UCL) found that the combination of high alcohol consumption and smoking increased the risk of hardened arteries in teenagers by the age of 17.
The study found that the combination of smoking and drinking by teens increased the risk compared to drinking and smoking separately.
Arterial stiffness is indicative of blood vessel damage which can be a precursor for heart and blood vessel problems later on in life, including heart attacks and strokes, even more reasons why teenagers should avoid alcohol and cigarettes completely.
