All my friends are always mixing weed with tobacco. They have nothing against it. But for me... I can't take full lung full smoke because my throat can't handle it. tobacco smoke takes half my lungful and that isn't what I like. I'm everyday tobacco smoker, but can'y tolerate mix with weed.
If you have less weed, but many tokers, then tobacco can be good.
I have find that with tobacco, the cannabis high is different than pure toke. But this is something all you guys know. I like pure one more.
Pure bud in bong is all I want.
