Some parents, however, have concerns. Teresa Miller believes marijuana triggered her son's dangerous drug habit.

 

"Twelve years ago, my son was smoking marijuana," she said. "Within a year, he springboarded to severe opioid addiction."

 

Miller is worried someone can now be caught with 20 grams of pot and face minimal punishment.

 

"Twenty grams is conservatively 60 joints. That's a lot. You're not going to be carrying that around for personal use. So I'm a little concerned that it was that high of grams. I think it should be less," she said. "I'm really hoping and praying that people don't decide, 'Well, since it's semi-legal and I'm not going to go to jail, that I can use it.'"
