Many got to be drug addicts thanks to the "boyfriends" who are now their pimps.

I'd say strictly speaking, "trafficking" means direct selling or trading in the object (or woman treated as object) being traded or sold. 
Does that mean I approve of the way advertising, the music industry, or the fashion industry (or a thousand other industries) uses women's bodies to promote products. That is  treating women as sex objects. So, hell no, I don't approve.  But that is another topic.
