Wouldn't a basic road side sobriety test do the job?
No. The effects of weed are not as pronounced as booze. Anybody with a tolerance (i.e., been smoking for some time) for weed could pass a road side sobriety test. Being stoned isn't the same as being drunk.
If you develop and market a road side test for weed, you will be rich.
Not true.
Which part? The weed effect vs. booze? I've never had to be carried out of a place because I was "too stoned". Can't say that about booze.
Passing a FST while stoned? Been a while since my last FST. Perhaps the test has changed. But I can walk a straight line, toe to toe, when stoned. Not so much when drunk.
Or the being stoned isn't the same as being drunk part? See previous comments.
Maybe the quip about getting rich if a roadside test for weed is developed? Please elaborate. The trucking industry would love this type of test. May get them more drivers.
Not trolling here. A sincere, honest question. Which, if not all, are not true? Be specific.
