Drug tests should be conducted on high school students because the costs of the drug tests do not outweigh the benefits. The benefits of drug testing students are far more substantial and significant than the monetary costs that come with testing.
Drug tests can deter and significantly reduce the rates at which students and high school athletes use drugs.
This is potentially a life-saving measure. If students fear the consequences of getting positive drug tests, they may choose to abandon the idea of using illicit drugs in the first place. Moreover, in an instance, where a teenager is caught to have a positive result of drugs and subject to consequences, the person is less likely to abuse drugs in the future.
Deterring students from taking drugs in the first place can literally save lives and the costs a school pays to administer these drug tests are worth it.
It is a state elected officials' job to make sure they are allocating enough funds to schools so they can have all the resources they need like certain books or counseling programs.
It is schools' job to protect and keep their students safe from harm and away from drugs.
