What happens if a dwarf rabbit eats marijuana?

It would fall asleep before too long. It may sleep for a while but then it would wake up with no harmful effects. Researchers working for the Federal Government have been unable to find a dose of marijuana big enough that it will reliably kill a rat. In humans, the lethal dose is at least one-third your body weight, consumed in fifteen minutes. see What is the lethal dose of marijuana? at http://druglibrary.org/schaffer/library/mj_overdose.htm
