Hardly any violence. Some characters have bad trips and imagine some disturbing images with little to no gore.
A man accidentally falls down to the ground while pushing his shopping cart. He hits his face so you can see some blood on it.
A man swerves his bike to avoid hitting a pedestrian, who, without checking both directions, tries to cross the road. He crashes into a stationary vehicle and falls off. In the hospital, he removes some of the gauzes, showing some blood on his arm.
A man is locked inside a car wrecking yard after dark. He manages to escape by jumping off the fence but it also injures him. Later we see him walking into a crowd, covering in blood in his abdominal area.
