I generally inhale slowly, but kinda hard to make sure I pull smoke through, kinda depends what I'm smoking. With joints I just let the smoke flow into my mouth, inhaling very lightly, then I will inhale harder to make sure I get a fat hit. With my glass pipe I just inhale kinda slow untill I see the weed in the bowl start to burn down then I will let off the lighter and inhale the rest while clearing it.
