text: i wondered at  RG:  ".....sheriff’s office has to pay to train its officers to detect drivers who are under the influence of marijuana..."  other than a blood test - what are the officers "trained" to do?  as if it was an unbiased decision to search or detain a "suspicious/probable DUII" driver who was high.  what is their criteria?  use dogs?  it would be nice to have that info.
