Child abuse is mentioned many times in the Juno Steel story line, as it is a prominent element of Juno's backstory, I would recommend against listening to the entire story line if it is a trigger for you.
Yes. Juno Steel is described as having a past addiction, and a character is heard taking addictive drugs onscreen (though not shown, as it is a podcast) in the following episodes:
Juno Steel and the Clean Break parts 1 and 2, Juno Steel and the Blank Slate parts 1 and 2, and Juno Steel and the Next Page parts 1 and 2.
The main character in the Juno Steel storyline struggles with addiction, and another character’s past heavily discusses a problem with addiction. Additionally, this character becomes audibly addicted to a drug from Juno Steel and the Clean Break part 1 to Juno Steel and the Next Page part 2 (and it is a major plot point).
In 2.02 a cat (though not the actual client’s cat) does have a bomb in it and does explode. There is also discussion of a beloved dog’s death, but it is revealed the dog was brought back to life (and is perfectly happy)
They're not technically rabbits. Beasts that are called rabbits. But there's a point where they're all being killed off-screen and the main character saves one.
A character stuns a dog with a blaster. When someone else is upset because of this, the character says something along the lines of “Don’t worry, it was set to stun. At least I think it was.” This is not clarified at any point.
[SPOILERS FOR JUNO STEEL STORYLINE: THE DRAGON'S DEN] at the end, a woman falls from a height too significant to survive. it is not explicitly described.
There is a very important plot point Juno Steel and the Final Resting Place involving eye mutilation that carries on to the rest of the Juno Steel story line.
In the side story Shaken a character severely injures her hands. It is described in detail. This story can be skipped and does not tie into the main series.
Annie, the younger sister of Juno's friend Sasha, was accidentally killed when they were children. The episode Juno Steel and the Day That Wouldn't Die takes place on the 25th anniversary of her death, and is heavily focused on the events of the day she died.
In the Juno Steel storyline, a character suspects their husband of cheating to the point of hiring a private detective, but there is no actual cheating
No one is ever possessed by ghosts or demons, but there are multiple instances of cybernetic implants taking over people's bodies in the second season of the Juno Steel storyline.
A main character in the Second Citadel story line worships a god of waves and his prayers to this god often have wave sound effects, and in the episode Lady of the Lake they all go to a lake.
[SPOILERS kinda] In Juno Steel and the Shadows on the Ship a trans character’s deadname is used in a flashback. Additionally, she is misgendered via auditory hallucinations
In Juno Steel and the Man in Glass Part one, a character is referred to as male up until it is revealed she has recently transitioned. No one makes a big deal out of it, and afterwards her correct pronouns are used by everyone.
The show's creators have said that the population of Mars is mostly LGBT, so many characters that die may be LGBT, but there are some characters that die and are confirmed to be LGBT.
[SPOILER, HOMOPHOBIA TW] during the Lady of the Lake arc of the Second Citadel story line, a character who is SGA dies, and there are references to cultural homophobia.
1. Many people in this universe suffer from severe radiation poisoning, which is typically mostly fatal. Two main characters have this, and there is a plotline about trying to find a cure for it.
2. In the later stages of Juno Steel, there is a major plotline about many people being kept on a sort of life support by medical means. While not explicitly stated to be terminal illness (to my knowledge), it is treated very very similarly.
There's shooting throughout the Juno Steel arcs, they're laser rifles but people do die Also two characters are forced to shoot eachother with pistols in Lesson Learned
