Has weed ever killed anyone?

Alcohol, if abused, can cause violence, sickness, and even death. People make rash decisions such as driving under the influence which can and has resulted in the killing of themselves and other people. Weed has never killed anyone, it is impossible to overdose on. I was thinking about this earlier today, when people went out to bars and it was the norm to smoke rather than drink I wonder how many people's lives could have been saved..
