I have a .10 ohm build on a single mech. I get tons of vapor. Does a stack give u more nicotine just cause its more powerful? Wud it be a noticable difference. And I already know Im ohming low. Thats just what I do. I like the power I get from this build. Nothings blew up yet. If my face blows off Ill take responsibility. I just want to know if a stack gives a noticable amount of more nicotine.
