Bernina,
I believe that the victims in this crime were herion Smokers. Does that change anything in your assessment? Can 2 or 3 people smoke $250 of H in a day? Can people who "maintain" still function normally, go to work etc.?
1 gram a day per person is still way too much with the current street level purity and still be "functional". Smoking, snorting, shooting...the only difference is how quick the heroin reaches the brain and the amount recieved.
1/2 a gram a day is more likely. A person would need a "bump", a small amount smoked or snorted every 3-4 hours to keep a somewhat consistent amount in their system. This could easily be hidden by lunch and smoke breaks during work.
Can herion and cocaine be combined into a "speedball" and smoked?
Yes.
Gianni seemed to have a steady supplier of herion. So why be obtaining the other drugs (xanx etc...)
For situations where disappearing for 15 minutes to smoke or snort heroin was NOT an option. Benzos dissolved under the tongue alleviate many of the physical anxieties and discomfort caused by diminishing amounts of heroin in the body.
Again, I think Gianni was buying more heroin than any of them used, simply to re-sale to cover the cost of their own use. At $250/day, that's $1650/week, $6600/month. You can't make that kind of money disappear if you're stealing from a business to support a habit.
If he cut/stepped on the product once, ie. added 100% "filler" (lactose, baking soda, etc), he'd have a salable product that was 40-45% pure, broken down in smaller quantities, 1/4 grams or less, he could make a 100%+ profit, thereby paying for their daily use and the purchase of benzos.
Would this still be the answer: Exactly.
