Depends, how rich are they in this hypothetical scenario?It's being poor that's the problem, and we know that's true because of the many rock stars who've lived with a heroin addiction for many many years.
If it's the first thing you think about when you wake up, and it kills you to sleep at night, and you think about it all day, sure, one's a highly addictive habit that destroys lives, and the other is heroin. Which is also a highly addictive habit that destroys lives. Funnily enough, one destroys lives because it's legal, and the other destroys lives because it's illegal. But if you're taking your phone to bed with you at night, and it's the first thing you check in the morning, before you even have a thought to yourself, okay, you're not injecting it with a needle under a freeway underpass but after you get fired for watching TikTok on the clock and can't pay your rent, is you're landlord gonna care when you don't pay rent whether you got fired for drugs or a smartphone addiction?
