Utopium is a fictional substance used in iZombie television series.
It first appears in the pilot episode with Blaine DeBeers, a major character in the show and the Seattle zombie world.
Vials of tainted Utopium when mixed with Max Rager will instantly turn its user into a zombie.
The primary sources of Utopium in Seattle are the Blue Cobras and Mr. Boss. However, throughout the series, there are many variations of Utopium that can be found.
Tainted Utopium
Besides the normal type, there is tainted Utopium (originally cut by Gabriel but discovered by Martin Roberts), which makes its users zombies when mixed with the energy drink, Max Rager.
Lucky U
Lucky U is sold by Blaine Debeers and his two main associates, Don Eberhard and Chief. It is another form of Utopium that directly rivals Mr. Boss's Utopium trade. It also mentions that it's cheaper and has "higher highs" and "lower lows".
