The only street drug the US govt has been able to effectively raise the price on is pot. Big, bulky, hard to transport and easy to find.
We spend tens of billions fighting drugs from coming in, from being sold on the street, and keeping 70% of the prisons full of non violent drug offenders, you think it's working?
The #1 cash crop in this country alone is pot. Even if they just legalized that and heavily taxed it's sale they could probably wipe out ALL OTHER taxes. Perfect time to shift the tobacco comapnies and farmers over and ban those deathsticks.
Not too mention the 500 or so products you can make from hemp, including food for animals and people that grows anywhere virtually, and would replace almost every petroleum product including oil and gas, that might help explain what you were wondering about, why the petroleum industry was behind one of the first, largest, and most cash induced lobbying efforts in US history in having Marijuana made illegal in the early 1900's.
Prices right now....
I just moved from Cleveland, the price for a quarter ounce of weed there was @ $50, @$175 an ounce.
Down here in SC it is $100 an ounce but the quality SUCKS.
Both places the world class stuff goes for $100 a quarter ounce.
AFAIK coke is still $100 a gram, but I don't play with that stuff or anything harder.
