It seems to be re-examined every year, but this time it is (once again) certain: weed is not bad for your IQ. Conclude researchers based on a large study in the UK.
In the Journal of Psychopharmacology they report that they could find no link between frequent marijuana use and a lower than average IQ.

The researchers took an IQ test in 2353 on eight-year-olds. When they were 15, followed by a second test. By this time, a quarter said they had smoked marijuana, and 3.3 percent more than 50 times.
CIRCUMSTANCES
The marijuana users had a higher risk for drinking, tobacco smoke, and problems at home. The researchers think that does not cause the weed, but precisely those other circumstances a lower IQ.
The frequent users also experienced no additional negative consequences: they scored 0.1 points lower on an IQ test.
