Through copious use of /spawnitem statuspod, I've confirmed MOST of the effects to be working. The following effects have been confirmed:

• Wet
  
• Slime
  
• Slow
  
• Frost
  
• Rage
  
• Glow
  
• Low Gravity
  
• Bouncy
  
• Speed Boost
  
• Healing (vanilla)
  
• Fast Healing (vanilla)
  
• Poison (vanilla)
  
• Fire (vanilla)
  
• Pixels (vanilla)
  
• Bomb (vanilla)
  
• All ore types (vanilla and modded)

However, I have yet to see a few pop in the wild. Those are:

• Tar (modded, Tier 3+)
  
• Swim Boost (modded)
  
• Doomed (modded, Tier 6)
  
• Overload (modded)

If you run into a Status Pod that either emits nothing on use, or the gas seems to have no effect, please post here with the planet tier and gas color (if applicable). If you are reporting an activation with no particle effect (no pixels, bombs, fire or gas at all), please include a pastebin link to your starbound.log.

Note on Overload: Overload is only technically untested - confirmed in 1.0, but reprogrammed in 2.0 to compensate for the fact that it is not caused by a weapon.
