It did.  I grew up around it, and was actively encouraged by my own parents to drink and do drugs.  The first time I ever tried crank was with my mom.  The first pot I ever smoked was stolen from her dresser drawer.  My first beer was given to me by my dad at age 8 or 9.  For Easter one year, he gave me and my brother (both single digits in age) an Easter basket and a six pack.  We were drinking beer on the front porch at 9am.

When we got older, we realized that when dad was drinking, it was a nightmare.  We were constantly in fear of him… but if we drank with him, we noticed that he lightened up and accepted us into his little group.  We also found that with enough booze in our system, that fear and tension eased up.

Once we got out on our own, we just continued to drink like it was a normal thing.  You needed groceries, a place to live, and beer.  It was as much a part of our grocery list as toothpaste.
