Dave-The 700,000 marijuana arrests for 2001 is probably accurate since the 2006 FBI stats are 800,000 out of 14,000,000 arrests. These are arrests! Not people that are going to prison. There's a big difference. The .7% and .3% are for the people acutally in prison for multiple marijuana charges and first time marijuana charges respectively. These stats are for marijuana only and do not include the cases where someone is charged with another felony and search incident to the arrest, weed is found and tacked on. I put the link for the FBI stats and the prison stats below. This was just a response to the plugging up prisons statement.

All of your prison stats are for drug offenses, not marijuana offenses. I can think of no better place for a crackhead than prison. These people comprise a huge portion of violent street crime. Pot heads, meth and heroin users will commit property crimes all day long to fuel their habit. I have seen dozens of people shot and killed because of something or another to do with crack cocaine. Let them rot...
