Don't smoke and post dude..."isolated cases" ?? there isn't a D1 school in america that hasn't dealt with marijuana arrests. Once again, you have chosen to listen to users instead of unbiased information. While overdose deaths don't happen often, they DO indeed happen. Other marijuana deaths happen all the time.....study released in October, 2012, found that individuals treated for addiction to marijuana had a higher mortality rate than those with diagnoses related to cocaine or alcohol, but lower than those with methamphetamine or opioid-related disorders.
