Red herring. Alcohol-impaired people are not allowed to legally drive. Employers don't permit EtOH-impaired people to operate machinery, engineer things, or whatever, except Corporate Execs get a pass. Probably why so many companies perform abysmally. I'd much rather be on the road with someone who is stoned, than someone who is drunk. I strongly support the legalization of marijuana. As do I. That is a particularly stupid prohibition. Particularly when you compare the social damage to that caused by alcohol. Or the health damage, both direct and indirect, caused by tobacco smoking. quote:
It's beside the point that I am going to make, but I don't support legalizing harder substances like methamphetamines, cocaine, various opiates, and hallucinogens. Like it or not, there is a problem with marijuana in relation to DUI laws and prohibitions on workplace intoxication. Alcohol intoxication is easy to test for, marijuana is not. A breath test for alcohol will determine if a person has enough alcohol in their system to be considered intoxicating. You can't do that with marijuana. When I read this, I recalled reading that blood testing was quite effective in detecting recent marijuana use. So I checked, by doing a Google search on the strings "marijuana blood test". And sure enough, there, on the very first link, was the data I was reaching for. quote:
Dear Alice, How long does marijuana stay in the body? Dear Reader, While marijuana itself does not actually stay in the body, some of the chemicals in the drug do. THC (delta-9-tetrahydrocannabinol), the substance in pot that's mainly responsible for people's high, may stay in the body forever — scientists aren't exactly sure. However, THC is only detectable for a certain period of time after using marijuana or being exposed to marijuana smoke. Compared to other controlled substances, THC is able to stay in a person's system for a relatively long period of time because it is fat-soluble. Being fat-soluble allows it to be stored in fatty tissues of various organs. From here, THC is slowly released and metabolized. This metabolite of THC is then excreted and cleared from a person's system. In testing to see if someone has recently used pot, there are two important substances to keep in mind: THC and 9-carboxy-THC. 9-carboxy-THC is a product of the body's metabolism of THC and, more importantly, it is detectable for a longer period of time than THC is detectable. This is the reason that drug tests, namely urine tests, look for 9-carboxy-THC. Many of the following numbers are estimates. The actual amount of time that these substances are detectable in a person's body depends on several factors, including how much pot is used, how often a person uses it, and the rate of his/her metabolism of the substance. Typical Periods of Time that Marijuana Use can be Detected‡ - Frequent Users*, Blood Tests for THC ---- 4 - 8 hours
- Frequent Users*, Blood Tests for 9-carboxy-THC ---- 2 or more weeks
- Frequent Users*, Urine Tests for 9-carboxy-THC ---- 2 weeks – 1 month†
- Infrequent Users**, Blood Tests for THC ---- 3 - 4 hours
- Infrequent Users**, Blood Tests for 9-carboxy-THC ---- 2 - 3 days
- Infrequent Users**, Urine Tests for 9-carboxy-THC ---- Up to 10 days
‡ Some private companies may use hair tests to detect possible marijuana use. Positive hair test results have been found to be unreliable. * Frequent users are defined as people who use marijuana several times per week, if not more often ** Infrequent users are those who use marijuana seldom enough that THC and/or its metabolite are no longer detectable before their next use. In essence, these users do not use pot often enough to allow for the tested substances to build-up from one use to another. † The detection period for 9-carboxy-THC in urine can be as long as 3 months in extremely heavy users.
