Leave it to the Texan to suggest building more prisons. Discounting the cost to build the prisons, assuming we had the room, it costs the taxpayers between $25k and $35k per year (depending upon which report you read) to incarcerate a prisoner.
Now, I'm not sure if you're aware of this, but according to the CDC, as of 2010, more than 1 out of every 5 American citizen age 18 to 25 used an illicit drug "within the last month." (21.6%)
Almost 17% of teens ages 16 to 18 used "within the last month." And over 13% of 26 to 34 year olds.

Let's think this through for a moment. To keep things simple, let's just stick with the 18 to 25 year olds, but remember that there are people older than this who also use illicit drugs. This is important, because I want to make sure you understand that putting over 20% of the population ages 18 to 25 in jail for 10 years will have a pretty dramatic effect on the economy. Sure, unemployment will go down because we will be reducing the working population significantly. But we'll also have fewer people working and paying taxes, to pay for your pretty serious proposition.
So, according to the US Census (
http://www.census.gov/prod/cen2010/briefs/c2010br-03.pdf), there were 30,672,088 Americans age 18 to 24 in 2010. If we prosecute and incarcerate 20%, that means we'll have 6,134,418 inmates... wow! Time $30k/year and we're looking at $184,032,540,000 per year. That's just for the 18 to 24 year olds and that's JUST for the illicit drug use.
To put your idea into perspective, according to the BJS, o
n December 31, 2010, state and federal correctional authorities had jurisdiction over 1,612,395 prisoners. http://www.bjs.gov/index.cfm?ty=pbdetail&iid=2230
So, what you're talking about doing is increasing the number of inmates in State or Federal custody by somewhere around 700% and that's JUST for the 18 to 24 year olds who are doing drugs.
Can we all agree that this is unreasonable?
