The middle and upper classes have been the ones out there pushing for decriminalization and legalization measures, and they have also tried to demolish the cultural taboo against smoking pot. But they themselves have chosen not to partake very much. Which is not surprising. Middle-class men and women who have jobs and families know that this is not a habit they want to take up with any regularity because it will interfere with their ability to do their jobs and take care of their families.
But the poor, who already have a hard time holding down jobs and taking care of their families, are more frequently using a drug that makes it harder for them to focus, to remember things and to behave responsibly.
