The first step to legalize marijuana in California is on a roll.

Lawmakers on Tuesday approved Assembly Bill 390 — legislation to tax and regulate marijuana. The Assembly’s Public Safety Committee voted 4-3 on bill at a hearing in Sacramento. The bill will now be passed to the full Assembly on Friday for consideration.

The bill, authored by San Francisco Assemblyman Tom Ammiano, would essentially treat pot the same way alcohol is treated under the law and would allow adults over 21 to possess, smoke and grow marijuana.

The law would also call for a fee of $50 per ounce sold and would help fund drug eradication and awareness programs.
