I'm not pro ciggarete, as a matter of fact i hate it but tbh, even if that experiment shows the "tar" % after 400 cig burned, its not realistic. No human smokes 400 ciggaretes every 3 hours, not even per day (if you wanna kill yourself it's cheaper/faster to buy a gun lol) and even if the cig has shit on it, as it says on the vid, the tar doesnt stay in your body 4 ever, you can eliminate it.
Even so there is not positive side on smoking tabaco.

Marihuana ftw :^p
