Is the Zammarak Spear Poisonable?

Tweet

I finally scored something from the Godwars dungeon. Several trips with a team to the Bandos chamber had gotten me bubkas so I veered off with a Zammie assault team. Nearly got my butt handed to me but I scored the spear ( This was before lootshare came out & I haven't been back since). The spear is pretty nice. It has the same stats & special as the dragon spear but with one bonus, SPEED. Now I'm wondering if its poisonable like the dragon one. I don't want to tag someone to make the superpoison if it can't be. Anybody know?
