I found this today; though I'd pass it on. FYI press 'next' on the right to see the after picture. it is of a woman (I don't know her) who has spent sometime on Crack cocaine between the first and the second picture. The first was taken sometime in the late 80's/early 90's (Judging by the shirt in the background.)  and the second just last month.

Edit: It appears the person that took these has made the pics private.  I can understand; although I do think the two pics served as an example of one of the many reasons not to get into drugs of any sort.  The body reflects the stress you put in it...
