Cigarettes kill but the psychiatric impact isn’t the same. The “high” one gets from potent weed leads to traffic fatalities in the short term and proneness to mental illnesses and psychiatric disturbance in the long term.
Traffic incidents on pot are not high speed murders like the drunks. The traffic accidents from stoners are bad parking, slow driving, and bad depth perception. I don’t suggest anyone drive under the influence…but your arguments are stereotypes from the 1950’s Christian Crusaders. Come into the 21st Century.
