http://content.time.com/time/world/article/0,8599,1917685,00.htmlKhat, which I have always heard pronounced like Gaat, is a shrub and produces a mild simulant effect when chewed. It grows wild all over the place and is found everywhere in the ME. It has been used there for thousands of years.
Also, in New Guinea there is the Beetle Nut, or the Betel Nut which is chewed all over the country. It is a wild seen because it makes the user's mouth bright red, and their spit is bright red as well. It is sold in all the street markets there. Be warned that the first few times you use it, you are going to get pretty bad diarrhea. Again, mild effect and used for thousands of years and it is very, very, common.
