Don't get me wrong, I don't think cannabis is harmless. However, a direct death caused by toxic THC levels is indeed unheard of. Birdgirl is correct in what she says, though. And she usually is correct in what she says. There are many angles to view how a drug can kill somebody. So yes, just as anything can be deadly, so can cannabis; however, cannabis is not toxic, and nobody has been able to prove that wrong as of yet.

Then again, everything that birdgirl said, while true, can still be attributed to irresponsible use of cannabis. Thus, we can conclude that irresponsible use of cannabis, as well as everything else, can be unhealthy and possibly dangerous. However, as we all know, cannabis itself is not a dangerous drug.
