Drug Trafficking

Sitting around under curfew last night, I decided to do some digging. At what point was it that drug trafficking first was officially recognized as a problem in Trinidad and Tobago and a solution proposed? I remember it as being a topic of discussion throughout the 1980s, actually. I suspect it stemmed from much earlier, perhaps the 1960s, but that was before my time - the 'older heads' would know more on that.
