If your talking about anxity attacks fine I agree 100%, but it is usually called a bad trip not an overdose. The scientific definition of an overdose means death.
The Drug Awareness Warning Network Annual Report, published by the US federal government contains a statistical compilation of all drug deaths which occur in the United States. According to this report, there has never been a death recorded from the use of marijuana by natural causes. Unlike opiates, barbiturates or amphetamines, there seems to be little risk from the use of large amounts of marijuana. When a person smokes too much they feel very tired and lie down. When people swallow large amounts of hashish, occasionally they get sick to their stomach.
damm you and your facts ;) You know marijuana kills, it makes people run over kids at the drive thru
