A bill has come into effect which partially decriminalizes marijuana possession across New York state.

"For too long communities of color have been disproportionately impacted by-laws governing marijuana and have suffered the lifelong consequences of an unfair marijuana conviction," Governor Cuomo said in a statement this week.

Residents can now publicly possess or smoke up to two ounces of marijuana without criminal penalties. However, police can still issue a summons for very small amounts of the drug.

The penalty would be $50 for possessing less than one ounce of pot or $200 for one to two ounces.

"This law is long overdue, and it is a significant step forward in our efforts to end this repressive cycle and ultimately mend our discriminatory criminal justice process once and for all," Cuomo said.

Bottom line, be careful where you smoke and how much. You can still be hauled down to the police station. This is only a partial decriminalization.
