i actually never heard about anyone overdosing on weed

Its not really possible as far as I know. People take insane amounts of THC edibles to see what will happen and they usually just pass our or puke. Then a hangover for a few days but not what we would normally define as overdose. A really bad trip. 

Often they THINK they are dying and end up in an er but its just parinoria.

Some people need high doses because everyones body is unique.
