The drug war may be finally losing support in Mexico, but it's happening when there is finally some evidence that marijuana is addictive. The new studies suggest that withdrawal has been overlooked because of the long half-life in the body for marijuana; symptoms are often worst in the third and fourth weeks after one quits ingesting the drug. That still doesn't change my feelings about the stupidity of the drug war...see Kevin Drum's latest.

Another interesting post from Brain Blogger on smoking is this one on the prevalance of cigarette smoking among people with schizophrenia.
