There are flashbacks to mob shootings where it shows the shooting but not the impact and does show pooling of blood.

Regular uses of 'Fuck', 'Motherfucker', 'Shit' and 'Asshole'

Regular scenes of drug use including smoking heroin and scenes where the man & woman are high from the drug use.

Also a few scenes where they snort cocaine

Some may find the armed robberies intense but there is no violence in those, just waving of the gun.

Also the overall film carries a somewhat constant intense feeling because they're always under the influence of drugs
