Cannabis can be fatal if...
1. You eat a handful of cannabis and choke to death.
2. A heavy crate of cannabis falls and crushes you.
3. You slip on a bag of cannabis and fall.
4. A serial killer's name is Cannabis.
One of the most interesting things about cannabis is the extremely low toxicity level. A fatal overdose has never been reported and its estimated that it would take consuming nearly 1,500 lbs in 15 minutes to achieve such a feat. Best of luck to anyone trying to do so however we would strongly suggest against attempting. A person may feel negative side effects when overusing cannabis with symptoms such as anxiety, paranoia or increased heart rate.
