A code word for an amount of marijuana. Originally 5.6 grams of marijuana or one 5th of an ounce. Often confused due to the term "dime bag" code for a $10 bag, the term "nickel bag" was never measured on that same scale. Many avid smokers use this to identify posers and noobs. Where a dime (ten cent piece) refers to ten dollars worth, a nickel (five cent piece) refers to 1/5th of an ounce. A nickel is in fact worth more than a dime when referring to an amount of marijuana.
