Go to NIDA's web site. While your there please learn something please and stop making me do your homework.
What's it matter if the pot is 25% THC or 5% or 9%? What matters is you aren't going to overdose on pot.
I challenge anyone to find me a case of someone overdosing on cannabis.
"The U.S. Drug Enforcement Administration Intelligence Division December Report 2000 states that a form of marijuana called BC Bud (British Columbia), with Canadian growers using sophisticated cultivating techniques, has increased THC levels from 15 percent to 25 percent, compared with 2 percent in 1970."
Okay, are you claiming that the average marijuana on the street in America today is 15%, or just that BC Bud averages 15% in THC? If so, why would you say "compared with 2 percent in 1970" when that was the average of commercial marijuana in the U.S. in 1970 and not "BC Bud?" That's an apples to oranges comparison.
If you are claiming that the average marijuana on the street in the U.S. is 15%, you are making a false claim. According to the ONDCP, it's closer to 5%, or at least it was in 2001. NIDA gets their data on marijuana potency from the same place the ONDCP gets theirs.

Just for you I went to NIDA's website and looked around and finally got linked to a DEA web page where they cite NIDA's numbers. You will not that in 2001 the average commercial grade marijuana was 4.72% THC and the average sinsemilla was 9.03% THC. It looks like the ONDCP rounded up on the commercial grade and down on the sinsemilla. The DEA web page doesn't say what the average of all marijuana seized in the U.S. was in 2001, but the ONDCP link I provided you said the avaerage of all types seized was 5.02%. Mostly what is out on the streets is the cheap commercial stuff. Most people can't afford to buy the expensive "connesuoir" varieties which while they may be more potent, are much more expensive and not as widely available throughout the states.
One other thing you will note from the DEA link is that the Marijuana Potency Monitoring Project is conducted by the University of Mississippi, and sponsored by NIDA. If you ever do any research on this issue, you will see that if our government provides sources for data on marijuana potency in the U.S., they'll always cite the Marijuana Potency Monitoring Project.
