Heroin: £55 per gram
One hit of heroin would likely be anywhere from 10mg to a few hundreds mgs. But by the gram, heroin is among the more expensive drugs, costing around £55. That compares to £46 for a gram of cocaine, £39 for a gram of ecstasy and £13 for a gram of speed.
#4 & #7... Not sure what I am missing here.. But it seems that if I grind my solid gold bars up into a fine powder I can increase it's value by 700%.. from $28 to $200 a gram??
