waiting,
I didn't mean to imply that all ex-JWs go through this sort of recklessness or that they as a group are less moral than the average person. I think it is safe to say, though, that many ex-JWs (esp. younger ones) do go through a period of doing some very destructive things -- drugs, drunk-driving, unprotected sex, etc...
I've talked with many ex-JWs who have said this is the case, in their experience. I've also studied about this topic with regard other high control groups. It's human nature, and makes sense psychologically. Usually, after a brief period of recklessness upon leaving, people do one of two things:
1) they go back to the dubs; I've seen this time and time again or
2) they straighten up on their own.
Marlene Winnell, in her book entitled "Leaving the Fold," wrote about this very issue. I think it is safe to say that it is a challenge for some.
