How do you keep a drunk in their house? How do you keep a lady on pain medication in her house? How do you keep that 99 old lady who shouldn't be driving even when she's sober in her house?How are you going to keep them in their house?
If the whole counter arguement on not legalizing pot comes down to DWI's. Currently how do they test people for driving while under the influence of other medications. There's no breathilizer test for anything besides alcohol, but people are arrested every day for DWI's that don't involve alcohol. Last time I checked it's done by observing behavior (both driving and street side tests). Same could be done for people driving under the influence of weed.
