Since you're new to smoking, cut down how much you're taking. A lot of people will adamently insist you have to finish at least the bowl, but that's crap coming from people who's tolerances are higher. Just take 2-3 hoots and see how you feel. Also, when you're new to smoking it will affect you a day or two afterward, mainly just making you a little mentally slower. don't worry, it'll clear up.
