a hookah isnt always for marijuana smokeing though it is a good way to smoke “weed” a hooka is a middle eastern way to smoke marijuanan opium and mainly tabacco hookah tabacco is thick and gooey with strings of sliced tabacco thre it. A hookah is a smooth smokeing expieriance and the substance you choose to smoke isnt burnt by flam you lite a biscut of charcol and put on the top know as a coal

well, a hooka is more something you smoke out of, not something you smoke. and some people smoke flavored tobacco out of it, others prefer marijuana.

A hookah is a type of smoking device. Some cities even have hookah bars where you go and smoke tobacco. I know that San Diego does at least. They usually have anywhere from 4-8 hoses coming off them so several people can smoke out of it at the same time. In Alice in Wonderland, the caterpillar is actually smoking a hookah. Hope that helps!

Simply put, marijuana will get you high and hookah(flavored tobacco pretty much) will not.
Most commonly marijuana(and to answer your question it IS also called weed and pot) will be smoked by means of a blunt(sort of like a cigarette) or a bowl [but people can smoke it from bubblers and other things but we wont get into that now]
and hookah(which actually thats the device not the substance) is smoked from a hookah which is this contraption with one or multiple hoses attached to it from which you breathe in the tobacco.
marijuana is smoked to get the high effect and hookah is a more casual, chill thing to do
