In its continuing efforts to be both helpful and informative, the Seattle PD has issued a public service announcement that discourages people from donating copious amounts of unused/unwanted marijuana.
No word on how often this happens, but it looks like at least one Seattle resident donated a 2.5-lb. bag of pot on October 17, 2013. Police were summoned and took the bag into evidence for destruction. To burn maybe?
The PSA does not mention donation of small bags of pot, so that may still be okay… in Seattle.
