Don't let Christine's elegant air fool you... she did her fair share of drugs just as EVERYONE did in the band. You really only hear about Mick and Stevie's drug problems, because they made them public, and were up front about them. Christine however, has always preferred to stay somewhat in the background, and is a more private person than the latter two. I'm sure she didn't think it was "proper" as it were, to make her substance abuse public. You can watch alot of the old documentaries and footage from the mid/late 70s... and Chris is absolutely smashed in every one of them
. I think everyone in the band just went about their own ways of dealing with their drug problems, and Mick and Stevie just felt it necessary to purge their problems to the public. -Louie
