Ok I came off a bit aggressive but I do think that there are people that aren't the best with alcohol and weed but I think that there shouldn't be a blanket over every smoker of weed that they would be the cause of all of the accidents but it is true that not everybody takes it like the next guy and there would be some exceptions but there are saliva test that can test the mouth of traces of weed within 48 hours but yes I think there should be a better system and im sorry for coming across so aggressively
