The Toxin applied via Tox Injector Implant, How much damage does it actually do?

You find this trait on head implants and I'm wondering how much damage does this actually add when it's applied? I know Toxin via plants last a long time and this one is more brief, but how much damage does this actually add from the implant Toxin alone? I wish this game had more advanced tooltips to say plainly how things actually function and the numbers behind them.
