1.
3.5 grams of marijuana. These other definitions are absolutely false. 3.5 grams * 8 (hence the name 'eighter') = 28 grams. A true ounce is actually 28.3495231 grams, and some European countries use 31.103 476 grams for an ounce.
I'm thinkin what to do... I know! I'll buy an eighter! 'den shmoke it. Werd.
