So I guess what I would really vote yes to is to legalize it but make laws governing it. Just like alchol we have breathalizers to tell if you are to intoxicated to drive. We could do the same for marijuana. I know we have the technolgy to do this. So what do all think about legalizing it if a "how high are you'' machine is made. lol

This can be done now: The FDA has recently given Epitope, Inc approval to begin manufacturing saliva test. In a study using RIA (Radioimmunoassay) test, cannabinoids were detected in saliva 4 to 10 hours after subjects smoked a single marijuana joint. Epitope has recently developed a test which detects drugs or their metabolites in saliva. However, this sort of test is limited to detecting very recent drug use. In one study, saliva testing was only able to detect cannabinoids 4-10 hours after the subjects had been smoking. It is likely that this test will be confined to detecting current intoxication only.

“Saliva testing has been touted as a "fitness for duty" test, as its window of detection begins as soon as a drug is ingested. Saliva tests will reveal only current or very recent (within the past twelve hours) marijuana use, but will detect use of cocaine, opiates, methamphetamine and Ecstasy over the past two to three days (urine will detect these drugs for three or four days after use). Saliva is typically experienced as cleaner and less intrusive than urine, and there are currently no known methods for defeating saliva testing. Saliva testing is useful for pre-employment, random, post-accident and for-cause testing. Both lab-based and on-site systems are available; the on-site system offers results ten minutes after taking the saliva sample. Saliva tests compare favorably in price to urine testing. "
