When it comes to attacking humans, grizzlies are equal opportunity maulers; attacking without regard to race, creed, ethnicity, or marijuana usage.
Hopkins’ use of marijuana to kick off a day of working around grizzly bears was ill-advised to say the least and mind-bogglingly stupid to say the most. However, I have been presented with no evidence by which I can conclude that Hopkins’ marijuana use was the major contributing cause of the grizzly bear attack.
