1. all but heroin
2. They can test if for whatever they want to just like any other drug test. However, the detection times are much more limited then other tests. For instance, marijuana will only show up on a saliva test for 12-24 hours after use no matter how often you use it. To put this into perspective, marijuana is detectable for about 30 days in the urine of a habitual user.
