1. my mistake, I was using big chart that was a few pages back. Though your couple of pages back was like 8 or 9....
2. Your charts prove nothing. Usage rates are vastly marijauna. That however doesn't mean or have anything to do with arrest rates and why people are arrested.
Thus to prove your claim, you would likely need to get a list of all drug related arrest records in the US, correlate those with usage and tie-in marijauna arrests. Citing drug arrests doesn't mean anything.
