I don't think the testing should involve middle school students. It's just too broad a net to cast, IMO, with all the costs and red tape that go along with implementing such a program across two school buildings. And I am hesitant to put a lot of stock in the results of "youth surveys" to determine the level of drug use and supposed trends before and after a drug testing program is implemented.
I'm also concerned about the provision for testing students "suspected of using drugs". In whose opinion? On what grounds? Under what circumstances?

so what kind of drug test is effective unless it is administered over and over again?

cocaine is out of the system in a few days.

THC can be tested for two or three weeks on urine, or in hair follicles for years.

don't forget marijuana is safer than beer!

if urine samples will be tested for THC, are daily breathalyzers going to be instituted as well to avoid the foolish hypocracy?

why not hair follicle test, so anyone that has been near smoke at least once will test positive and the newspaper can gasp and wow at more useless statistics.

step 1. survey the students to see if they use drugs
step 2. believe the results of such a survey
step 3. ?

what can be done that could possibly be considered progress on this quest to failure?

i have to agree that the teachers and administrators should go thru testing as well.

Teachers need to be tested before the students as far as I am concerned. I think the results would be shocking.

It`s none of their [the schools] D@NM BUSINESS .

It is time for our schools to start doing their jobs, EDUCATE our children!
No wonder that for years Japan has produced much smarter graduates than the US.
