Maybe not.  A gal was just arrested a few weeks back for poor driving and she only had drugs in her system . There is no doubt alcohol is worst , but those pushing legalizing pot implied by legalizing it , more people would use that and not alcohol.  Smart people knew people will always mix pot and alcohol and that by legalizing pot , we were increasing the problems on our roads.  They said pot causes no problems when it does. Any time you have more messed up people , your going to have more problems.  That's a simple fact of life.
