1) its SALIVA drug testing, not testing for salvia 2) please only answer if you actually know, preferably if you have taken a saliva test and know about it, etc. dont just guess or look it up on google that does us no good 3)PLEASE do not start lecturing about not doing drugs. i mysef dont do drugs and my sister (whom im asking about) will not see this page, so you're not doing anyone any good, just annoying. ok :) my sister has to take a saliva drug test on saturday for a job. she is NOT a frequent drug user at all, but on saturday it will have been about 8 days since she last did a teeny bit of cocaine and about 12 days since smoking weed. we looked it up online and it looks like they will show up for about a week or less, unless you are a habitual user which she is definitely not, the only problem is that in the last month, she has smoked weed several times but before then, she probably smoked once every 6 months. any thoughts? is she going to pass? any tips on passing? thx um, not really trying to cheat, we just kind of want to know if you've taken one and know how long drugs stay in your system, particularly in this situation whats with the hostility latina.chihuahua? can you just answer a question without being oddly hateful?
