Many things can become an addiction.

Usually one of the first substances teens run into, at a party, at a family dinner, in someone's basement. Because the teen brain is still developing, alcohol hits memory, mood, and impulse control harder than it does for adults. That's why one night can sometimes feel like it derails a whole week.

One pod can hold as much nicotine as a pack of cigarettes, and modern vapes are designed to hook a teen brain fast. A lot of people describe quitting as harder than anything else they've tried. If you can't sit through a class without your hand drifting to your pocket, that's worth noticing.

Daily teen weed use is linked to changes in motivation, anxiety, and learning. It's not the harmless thing TikTok makes it out to be, especially for a brain that's still wiring itself. Other substances, pills, stimulants, opioids, carry real overdose risk, especially with how much fentanyl is floating around now.

Games are literally designed to keep you in them: variable rewards, social pressure, never-ending progression. Healthy gaming is a real thing. Gaming that's eating your sleep, school, and friendships is something else. If you're skipping meals or lying about hours played, your brain is telling you something.

Endless scroll is engineered to be hard to put down. A lot of teens describe a low-key anxiety that only goes quiet once they're back on their phone. That's not a personality flaw, that's the design working exactly as intended.

Sports betting, in-game loot boxes, crypto, online casinos, gambling has never been more accessible. The teen brain is especially wired to chase losses, which is exactly how a casual $5 parlay turns into something you can't talk about.

Buy-now-pay-later, TikTok shop, drop culture, and consumerism, it can all turn shopping into a way to regulate your mood.

Binge eating, restricting, compulsive 'clean eating', these can become addictive in their own way. If food is loud in your head, like, way too much real estate, that's worth talking to someone about.
