For a first time user I would say a joint if its accessable and you have a good place to chill outside and smoke. That way, they'll be able to monitor the size of the hit they want to take - and the high comes on the fastest with a joint so they won't over smoke themselves with the possibility of having a bad experience. As for the hookah - I personally say leave the hookahs for the flavored tobacco, there are so many chill ways to smoke pot alone other than a hookah. I also prefer to not mix tobacco and pot all together - sometimes I enjoy a cigarette after smoking pot just because it increases the body high. I never roll my joints with tobacco and never mix tobacco with pot in hookahs. Enjoy!
