Ive never heard of Charlie Sheen OG until a few hours ago. Went and picked up a couple grams and i can say it's definitely fire. Very nice smell(not too loud but not too quiet) and the buds looked so nice and frosty like the first snowfall of winter. the effects set in maybe the first 4-6 hits which is pretty quick for me because of my high tolerance. it was like i got a sudden burst of energy out of nowhere but then as fast as the energy came it quickly left....made me lean back in my chair lol. but Overall i love it. its not as strong as Cookies Kush but effects wise, its up there in my opinion.
