While gram, ounce, half, quarter, pound, etc. are all formal terms for the measurement of weed, there are a number of slang terms as well. A gram of weed is often called a ‘dime bag’ in informal language. Similarly, if you want to buy two grams of weed, you’re probably going to ask for a ‘dub of bud’ - which is 2 grams. An eighth of weed is often called ‘half a quarter’ or even a ‘slice’ in some places. Quarter of a bud is commonly called a quarter and there’s no specific slang for it though you may see some people calling it two-eighths. When you go out there to buy half an ounce of marijuana, you may hear slang terms such as ‘Half an O’, ‘Half a Zip’ or ‘O by 2’. A full ounce of weed is often called a ‘zip’ of marijuana. A quarter of a pound is called a QP.
