What are the affects, consequences of drinking and smoking underage? how can the young person then get support on how to stop them from drinking and smoking?

Well i just gonna list what i've learned from my studies. Drinking and smoking can cause damage to the brain.

For example:  Smoking can get you addicted to nicotine which isn't bad by itself until you get the other chemicals mixed in it which creates black tar in your lungs and throat and burning paper or ashes which can make breathing and getting oxygen to your blood way harder.

And drinking can make your reaction times slow, impair your vision, and make talking, memory, and walking a challenge. But if you are drinking consistently some of these effects can be permanent and last long after you've become sober.

the answer is a 100% b) communism

hope dis ya ; )
