That's not really how it works in Harrisburg. Literally thousands of bills are written every session, and only a fraction of them ever come up for a vote. Just because a Senator or Representative authors a bill, that's not a guarantee it'll be considered at all.

That being said, you're starting on the right path to do what we (the public) need to do to get our government to work for us, instead of Pennsylvania's long-standing requirement that we work for Harrisburg.

Contact your state representative and state senator. Be agreeable yet persistent. If they tell you they support the bill, ask if they're working to advance it in committee and toward a vote on the floor.

Legislators don't obsess over how they love writing legislation as a means to get re-elected, they focus on doing the bare minimum for as many people as possible to make them content enough to vote for them again. Make sure they understand when you're talking to them that "pro-marijuana" stance isn't enough, for you you're also requiring active participation.

Get your friends to do the same. One person can start the ball rolling but an army of activists are going to see better results quicker.
