Many companies are turning to saliva tests. These can be done by almost anyone and on the spot. If you go for an interview and they offer the job they may pull out the ole swab. They know you cannot cheat and the only good thing is it only detects use for about 72 hours. I've seen many people get surprised. Lowes uses this technique. I know a guy who went for the second interview and got the offer. They then pulled out the swab and took his saliva. They can take the swab but then they have to send it to the lab. He failed and ended up sitting at home with his many dollars spent on urine subs and delivery devices. I suggest that you abstain for 4 days at least if you know an interview is coming up.
