Legalizing the home cultivation of cannabis by persons who are 21 years of age and older.

SB 6204 legalizes home cannabis cultivation for Washington residents aged 21 and older, allowing up to six plants per household (with a maximum of 15 plants total for a single residence). It sets specific limits on cannabis products, including 0.5 ounces of useable cannabis, 36 ounces of liquid-infused products, or 100 milligrams of THC per 24-hour period for noncommercial sharing. The bill prohibits visible cultivation from public view or neighboring properties and maintains criminal penalties for exceeding these limits or for possession by those under 21. It explicitly excludes medical cannabis patients (covered under separate law) and clarifies that commercial cannabis regulations remain unaffected.
