It is a complex formula to calculate the price per hit for drugs.
You need to calculate the cost to replace the stolen goods, the insurance excess for the break & enter, the cost of repairs for the damage done during the break & enter, the cost of medical treatment and counselling for the shop keeper or servo attendant that was held up at knife point, etc, etc, etc.
Sure, the drug user may only pay $20 or $30 per hit....but the cost to the community probably isn't far off that $1000 per hit figure.
