A NEW HIGH FOR MARIJUANA IN U.S.

The marijuana being sold across the United States is stronger than
ever, which could explain a growing number of medical emergencies
that involve the drug, government drug experts Wednesday.

Analysis of seized samples of marijuana and hashish showed that more
of the cannabis on the market is of the strongest grade, the White
House and National Institute for Drug Abuse said.

They cited data from the University of Mississippi's Marijuana
Potency Project showing the average levels of THC, the active
ingredient in marijuana, in the products rose from 7% in 2003 to 8.5%
in 2006. The level had risen steadily from 3.5% in 1988.
