Meth today is like alcohol back in the Griffith days. Except it is much more dangerous both for the person using it and people that might get in the way of that person. From what I've seen and read, meth addicts go to extremes faster, especially when trying to feed their habit. I don't think your gf's parents would feel as unsafe if there wasn't as much meth use in the area. Also, there seems to be more help for alcoholics now than back then. That isn't the case for meth yet.
