A mother claims marijuana killed her son by triggering a heart arrhythmia.
Michael Ziobro, 22, was found dead on his bedroom floor in New Jersey by his mother Kristina in April.
Paramedics attempted to revive him but he was already unresponsive, according to the medical marijuana report.
But his family believes he died from smoking marijuana because the medical examiner found traces of weed in his blood.
Now, Kristina and her husband Victor want everyone to know that marijuana with high levels of THC caused the condition that killed him.
