What adjectives can I use to describe people who are promiscuous, use drugs, and do other things that are traditionally frowned upon by society, especially the older generation (like the teenagers from the TV series Euphoria)? I feel like I forgot some word for that but thesaurus couldn't help me. I would appreciate if you offered several options belonging to different styles (neutral, formal, slang).
You might say they were reckless, or lived / behaved recklessly.
This article titled "why do some teens behave recklessly" uses that expression to describe:
"the cavalier behaviour of teenagers — driving too fast, engaging in unprotected sex, dabbling in illicit drugs"
