I'm native american am I more susceptible to becoming an addict?

NO!!..........but... It's really about you! although certain groups have more issues with drug abuse and addiction, it ultimately comes down to who you are......Do you have a job that you enjoy?....Are your friends and family plagued with drug problems?.....Have you been mentally, physically, and spiritually healthy? If you are at a party and are offered drugs, what will you do? Do you know how to just say "no"?
Depends. Depends on your attitude about drugs and alcohol, native americans has 11% chance of addiction compared to 8% in other ethinic groups.
