im not sure but i dont think ive ever mixed (USA) but im not opposed to trying it, i can see where it would increase the buzz al il or give u a lil head rush just like a cigg would after a nice tokey tokey, but dont get me wrong i used to smoke ciggs i got addicted and quit b4 it was too late, i hate them! but nicotine is quite relaxing :rasta: :thumbsup:
