Man ya'll dunno shit. A French inhale is holding the smoke in your mouth, blowing it out slightly and then taking it through your nose. No you don't get higher by doing so, if you do it's not noticable. Also, the reason Coke fucks you up so bad is because it cuts the membrane in your nose allowing the drug to get into your bloodstream and then your brain in seconds, this is also the reason long term coke heads get nosebleeds. It slowly eats away that membrane in your nose and eventually you can stick your finger up one nostrill and out the other, fun huh?
