This week, the Seattle City Council announced that it had passed legislation which established the fine for consuming pot in a public place. The amount of the fine will be set at $27, which is the same as for the offense of drinking alcohol in public. However, the council also stated that law enforcement officers should provide a warning "whenever practical" before issuing a citation - meaning that cops probably won't be pulling out their ticket books the instant they see someone smoking marijuana.
This announcement by the city council presents an opportunity to clarify some of the rules regarding pot consumption in Washington next year.First, the $27 fine obviously only applies to infractions within the Seattle city limits. Other municipalities have the right to set differing fine amounts for public marijuana consumption - although those fines cannot exceed $50 according to the new statutes.
Also, the act of smoking pot is also regulated by ordinances prohibiting all smoking in public places. So even if you aren't technically smoking a joint "in public," the codes that govern the building or outdoor space where you are lighting up may ban that activity.
Since the fine is for "consuming marijuana in public," that means that technically speaking, people are not allowed to vaporize pot or even eat a marijuana-infused brownie in a public place. That said, you probably shouldn't expect cops to thoroughly inspect all baked goods that they may see.
