Reply #45: When it is legalised people will be in a better postition to know their limits.

How often do you pass people who are driving stoned? Probably every time you drive.

Maybe when it's legalised they should prohibit driving stoned for a few years until society adjusts; then introduce limits.

We already have roadside pot testing in Australia (saliva strip with follow-up blood test) but it isn't very common (I don't know anyone who's been tested).

One study in 2005 in Australia showed 1 in 50 people were driving with any amount of either speed, pot or ecstacy in their system. Only 1 in 250 were driving beyond the Australian alcohol limit of 0.05 (It would be interesting to know what proportion had any amount of alcohol in their system).

edit: according to the article, the 1 in 50 statistic was an underestimate as the saliva tests are not as accurate for pot as for speed.
