After more than a decade of failed attempts, supporters of amending Washington state law to allow homegrown marijuana say they are growing frustrated, but not giving up. Advocates argue that allowing homegrown cannabis would not significantly hurt regulated retail sales and that penalties for growing at home disproportionately impact people of color. This marks the 11th consecutive year lawmakers have introduced legislation to allow home cultivation since Washington legalized recreational cannabis in 2012. Washington is one of only three states that have legalized both medical and recreational cannabis but still prohibit homegrown marijuana. Advocates say legalization of homegrown marijuana is inevitable, but remain uncertain how long it will take.
