I started a thread about this today.
Its titled O.G. kush mystery solved!??!!?
I thought it was kind funny how the article is called the birth of bubbakush and then WHAM, hey there how about the origins of O.G. as well. Like its some insignificant detail of the story. But i did find the article very intresting and a lot more likely than some others ive heard.
HighTimes is a very questionable source and has raised many questions on their ethical practices. I would take Hightimes info with a grain of salt.
