🚨 NEW STUDY: Cannabis isn’t harmless.

People who start smoking weed to “self-medicate” face higher risks of depression, paranoia, and psychosis.

The data is damning — and it’s especially bad for teens.

THREAD 🧵

2/ Researchers at King’s College London found:

• Self-medicating users consumed far more THC than others.
• They reported higher rates of anxiety, depression, paranoia.
• Using it to “treat” mental health often worsened mental health.

3/ Starting weed use for “fun” or “curiosity” = fewer negative effects.

Starting weed use for “anxiety” or “depression” = far more paranoia and depression.

Translation: the myth of marijuana as “medicine” for mental health just collapsed.

4/ And teens? It’s even worse.

A separate 2024 study found cannabis users were 11x more likely to develop a psychotic disorder (like schizophrenia).

Adolescents are uniquely vulnerable to permanent brain changes from THC.

5/ The results also tie weed use to childhood trauma.

Researchers found trauma + cannabis = a dangerous multiplier effect.

Cannabis didn’t heal trauma. It amplified paranoia and worsened outcomes.

6/ Here’s the bigger picture:

Legalization was sold as harmless, even beneficial. But the data shows cannabis use fuels:

• Mental illness
• Psychosis
• Crime and violence
• A generation of addicted young people

The costs are staggering.

7/ Bottom line: 🚨

Cannabis is not “medicine” for mental health.

It fuels depression, paranoia, and psychosis — especially in teens.

States were wrong to approach this issue without caution.

Science is catching up to what common sense always knew.
