However, the GP's suggestion could easily have been used as a good band-aid while their expensive 'solution' was being developed ...

Not disputing your point about other additives being the main problem - I don't smoke, and neither do I know much about cigarette carcinogens - but if
1) practically all cigarettes contain nicotine
2) non-cigarette use of nicotine is extremely rare
3) it is far easier to test for than whatever actual crap is there in the cig.

then it still makes sense imho to test for nicotine as a simpler way to indirectly test for smoking.

Hmm - eventually maybe there will be weapons that are factories ... fire a missile into ground on enemy terrain, and it sets up shop creating hunter killer drones to eliminate any life nearby!

Offtopic, but I checked out of curiosity - you can post G links with just imgurl & imgrefurl taking out the rest and it will still work, makes for links that are a little less like paragraphs ;)

You might want to look at prepaid, no $10 plans but there is a new $30 plan with 1000 mins/1000sms/30mb (Straight Talk) from TracFone and supposedly Page Plus will have a $20 plan with 500mins/sms sometime next month. I'm seriously considering both, or even if I wanted to continue paying around $47/mo. which is my current bill for T-Mobile ... I may instead switch to Boost with $50 unlimited everything, that way I get to browse & use SMS too for the same cost. My current (postpaid) plan is just 1000 mins, no incl. sms or web ... I was thinking of getting another contract and picking up an Android phone, but it makes more sense to cut my bill to ~ $25 with PP (assuming some taxes) and just pick up whichever phone I want for full price.
