Summoning dropped items (arrows)

/summon Item ~ ~3 ~ {Item:{id:tipped_arrow,Potion:"long_weakness",Count:1}}

I need help with this. How do I summon a dropped item that has tipped arrow affects? This does not seem to work.


Item data that is not the root id, Damage, Count, and Slot, must be placed within a single tag compound:

/summon Item ~ ~3 ~ {Item:{id:tipped_arrow,Count:1,tag:{Potion:"long_weakness"}}}
