Seem to get higher if I'm taking constant rips, me and my buddy use to do this when we were in high school
we would have like two pipes, both packed, One of us would hit one, take a decent rip, take a drag of a cig, exhale, as soon as you do that, cash the bowl, take a drag, exhale, take the second pipe right away, inhale, ect. That'd get us pretty headrocked/baked after
