2419 NE Sandy Blvd., 503-894-8774, pdxtreehouse.com. 10 am-10 pm Monday-Saturday, 11 am-6 pm Sunday.

This large shop is the unofficial starting point of Sandy Boulevard's Green Mile. It's also one of the top Portland shops for concentrates, extracts and edibles. With a recent renovation making room for much more flower, this still tends to be the place to recommend for the best non-flower items. CBD capsules powerful enough to help heavy users deal with pain are a steal at about $3 each, and the selection allows for one-stop shopping for tourists or those looking to buy a bag of green to share with friends.
