Random drug testing is here, but is it another example of big brother? No one wants those under the influence of any substance, that impairs their skills to take control of a vehicle or machine.

As many drugs are illegal there can be no safe limit, unlike booze which is a legal substance. With insufficient knowledge to make reasonable legal judgments then should we have as a penalty the canceling of a drivers license and all that this action entails. How much does the time between exposures to drugs and the time of the test relate to driving ability?

Is it true that front seat passengers can be tested and also loose their license? Isn't this taking extreme action, the passenger may have been taking responsible action by not driving. What if the vehicle is a taxi and the driver fails the test, and the passenger? I think I will start riding in the back of all vehicles when under the weather, regardless of the reason.
