Back in the olden days lots of the weed you purchased often contained much leaf material. Flowering buds was available also but the choices were so limited compared to today. When buying you'd say give me some Jamaican, Colombian,hashish,etc.
Of course I could buy a kilo of high quality Columbian for about the same price some of you pay for an ounce nowadays.
That's 2.2 pounds I believe. I'd then sell about half and would leave about a pound free for my own personal use.
