My best friend is a Assistant Police Chief in a nearby area.
They occasionally set up night time DUI check points.
I believe the last time they charged 7 people with Driving under the influence. The break down was 2 for alcohol and 5 for drugs. I believe 2 of them claimed they had medical card for pot.
The Good Samaritan drug act has hindered police from trying to stop the dealers of drugs. Charges are only brought up when a person dies from an overdose.
Seems to me if you allow the poisonous snake in the room it's going to eventually bite somebody.
