Lt. Gov. John Fetterman supports legalizing cannabis
The 140-page bill would legalize, tax and regulate recreational cannabis
Oregon Sen. Ron Wyden proposed the legislation on Friday
It's unlikely to pass as lawmakers are working on a more restrictive proposal
Legalization would generate $350-$750 million in taxes annually
"We'll work very hard to get it done"
The legislation includes strong public health and safety provisions
His Lt. Gov. will hold listening sessions in all 67 counties in PA
Republican legislative leaders are opposed to the move
"I just want to make sure we do it correctly"
