Just to name a few, I do drugs, momma say it's in my blood
But she don't know what the fuck I've been through
No matter what his mom says, she wasn’t and isn’t in his head 24/7. Not that she doesn’t understand — apparently drugs have always been in their family — but hell she just doesn’t know. Ab likely doesn’t believe that the reason he engages in drugs is predetermined by his family history, and rather his life experiences are the root of his indulgent. He could also be referring to the fact that his mother says that the drugs have gotten to him (are in his blood) and have changed him for the worse which would explain the rather violent response to his own mother.
