Rep. John Fleming (R-LA) warned about the dangers of marijuana, arguing that weed is worse than cigarettes and has caused an increase in the number of homeless people moving to Colorado.

Fleming’s comments came during a speech at the Values Voter Summit on Friday.

Fleming said that the social experiment of Colorado allowing recreational pot sales has not “brought an avalanche of revenue.” Instead, Fleming said, it’s caused an increase in “the number of homeless people” moving to Colorado.

In the same speech Fleming argued that marijuana is not, in fact, harmless by saying that marijuana contains qualities that are “four times more potent than tobacco, which is known to cause” cancer.
