It is a trick!
The BEFORE photos are of people who are younger.
The AFTER photos are invaraibly photos of people who are older.
So, of course, most people look worse as they get older. As people age, they will look worse whether they use drugs or not. Compare any photo of someone, anyone, in their 20’s to how they have changed, for the worse, 20 years later.
I can show you the same BEFORE and AFTER effects of someone who has been drinking milk for 20 years.
