Yea it is the same as half an 8th (or 8ball as in cocaine) which is called a 16th or teener.
1.9 with bsg
1/10 of an ounce teener
My son weights 160 lbs.
That would be a "teener" which is 1.75 grams
quarter - quarter of a gram half - half a gram teener - 1.8 grams
-Twenty - Thirty a gram. / 40 a Teener/ 60-70 a 8ball -Two hundred twenty-five to three hundred an ounce.
Here in San Antonio, TX a teener is $40.
It really depends on who is buying it. A 20 is a 20 it can weigh anywhere from .15g to .25g. It is supposed to weigh .25g but most people just eyeball it so unless you request a 1/4g you will pretty much get what you get. That has always been my experience. So if you are worried about it be specific and ask for a quarter or a half or a G.
