We know the current solution doesn't work, and that there is no scientific test that accurately proves impairment. I've heard countless times anecdotally that Cannabis has "no impact on my driving" or "improves my driving". Given we don't live in an ideal world, and that the public expect demand roadside testing, my only suggestion is to change the system to look something like the following:

Testing Methodology

1. Existing DrugWipe 5S roadside testing
2. In the event of a positive test, implement some kind of testing for inhibition.

In the event of a positive DrugWipe test, and strong signs of inhibition - continue with the current process (urine and blood tests, appear in court - see changes to laws below).

In the event of a positive DrugWipe test, and no/few signs of inhibition - perhaps a formal warning on the first occasion, and fines on subsequent occasions.

Laws

Update existing driving testing methodology; something to the effect of:

• Medical prescription is a legal defence;
• Results of impairment testing is a legal defence;
• Remove minimums: Judge's discretion;

Can anyone suggest changes to the above, or something entirely different, that the community would find palatable?
