Ever wondered what it is like to drive under the influence of marijuana?

In the US - with many states legalising the drug - news agency CNN conducted an experiment in having three people smoke the drug and filmed them taking some driving tests while under the influence.

The test was undertaken with the co-operation of a Washington sheriff's department and were a little surprising. Even at five-times the state's legal limit of marijuana in their system, the three testers were able to safely drive the car and appeared to be more cautious than normal.

However, once they began to smoke more cannabis, driving became much more erratic and carefree.
