Recreational marijuana just got one step closer to being legalized, after two Pennsylvania senators unveiled a new bill.

Senator Daylin Leach, and co-author, Senator Sharif Street are circulating their latest proposal, Senate Bill 350, to colleagues for co-sponsorship.

The bill would allow anyone 21 and older to use recreational marijuana in Pennsylvania, and each household could also grow up to six marijuana plants at a time for personal use.

The bill also allows home delivery of marijuana.

Using marijuana in public would still be prohibited, but regulation will allow businesses to permit the use of cannabis.

Those businesses could include cannabis lounges.

The bill would also allow small state farms and businesses the opportunity to participate in the new industry by growing marijuana.

Growing micro-licenses would be done by tier.

Tier one license holders could grow up to 12 plants at a time, including at their home.

Tier two license holders could grow up to 40 plants at a time.

Tier three license holders would be required to have a grow facility but could grow up to 150 plants at a time.
