Using these numbers, you can get a ball-park idea of how pure your heroin actually is. For example, San Francisco's $40 per gram heroin must be ($40 Ã· $300) 13% pure.A $40 gram in Amsterdam would be ($40 Ã· $125) 32%. Determining the actual amount of heroin you are doing is just as easy: just divide the average amount you are spending on heroin each day by the retail price ($300 or $125).This means that a person with a dime bag per day habit in the United States is doing 0.033 grams (33 mg) per day.otal Use Vs.
