The newly reported herbal plant being abbused now a days is the Khat Drug.
Khat (Catha edulis) is a flowering shrub native to northeast Africa and the Arabian Peninsula. It has stimulatory effects, which are similar to but less intense than those caused by abusing cocaine or methamphetamine.
Khat typically is ingested by chewing the leaves—as is done with loose tobacco. Dried khat leaves can be brewed in tea or cooked and added to food. After ingesting khat, the user experiences an immediate increase in blood pressure and heart rate. The effects of the drug generally begin to subside between 90 minutes and 3 hours after ingestion; however, they can last up to 24 hours.
The use of khat is accepted within the Somali, Ethiopian, and Yemeni cultures, and in the United States khat use is most prevalent among immigrants from those countries. Abuse levels are highest in cities with sizable populations of immigrants from Somalia, Ethiopia, and Yemen, including Boston, Columbus, Dallas, Detroit, Kansas City, Los Angeles, Minneapolis, Nashville, New York, and Washington, D.C. In addition, there is evidence to suggest that some non-immigrants in these areas have begun abusing the drug.
