My uncle shoots heroin. My father used to do cocaine. My moms' (both of them) used to smoke weed with their friends when I was eight. I smoked weed when I was twelve. I sold weed at 14.
I don't want to continue in the vein of my addictive family (no pun intended). How hereditary is addiction? What measures can I take to avoid falling into the same hazy trap of my family members?
