It goes further than that in CA. Any place a pedestrian chooses to cross a street becomes a crosswalk -- marked, or not. I noticed in my old home town last summer that they have constructed immpermeable fences down the median strips to prevent people from crossing in the middle of blocks.
The problem that I see is that cannabis stays in your system for a long time, while the effects of it are over in hours. So if you smoke a joint on Friday night, it’s still technically in your system on Monday, even though you are no longer feeling the effects of it.
This is unlike alcohol, where we have the technology to say to someone, “you are legally drunk!” by testing them and finding alcohol in your system.
One of the challenges for law enforcement would be to have a field kit that can test for “current” THC levels.
Isn't that so California? Rather than change a stupid assed law to mark crosswalks and hand out jaywalking tickets elsewhere, they build barriers to force people to use crosswalks. Or so they think. California is populated by thousands of experienced barrier climbers. What's going to happen the first time one falls off into traffic?
