I think companies drug testing their employees or potential employees is a violation of privacy and serves no purpose but to stigmatize and discriminate against drug users. CMV

I think that a company requiring its employees to submit to drug tests is a gross violations of the employees right to privacy and harms society by denying drug users legal means of employment which in my opinion is a large factor is the the increased levels of criminal behavior among drug users. Companies are not allowed to view your facebook page or ask your sexual orientation or personal beliefs when interviewing potential employees why can a company investigate your drug use? Wether I abstain from all drug use, am a raging alcoholic or use drugs recreationally it shouldn't be any of my employers business what I do on my own time unless it interferes with my work. such as coming into work high or being to hungover to work properly.

Using drugs is actually illegal, though - that's the difference. If companies want to know whether their employees/potential employees are breaking the law, they have a right to know that.

Also, as for the title of your CMV, you claim that drug tests stigmatize and discriminate against drug users. Sure, but why is that a bad thing? People who use illegal drugs are criminals. We want to discourage crime on a societal level, so we therefore should discourage drug use. 

Furthermore, the reality of it is that being a raging alcoholic or using heroin does interfere with your ability to work. Some drugs probably do not, such as weed, in which case the issue is purely legal. In any case, someone who uses drugs signals to the world that they are willing to break the law and put their health at risk for the purposes of achieving some short-lived satisfaction.
