tecatas

A female who is a hard core drug abuser. Often Heroine users.

I know the word tecato, as a herion user, never heard of tecata,
, maybe a female user?

Female drug user(commonly in hispanic circles).female junkie or drug dealer in a hispanic neighbourhood or city.

"Tecata" had already meant heroin for decades -- both in NYC and in Puerto Rico -- when I learned the word in the early 80's.When I lived Puerto Rico in 82-83, the most common words for junk were "tecata" and "manteca".
I've never heard a junky called anything else but "un tecato" (or "una tecata", if a woman)by Boricuas.
