Tell Your Children: The Truth About Marijuana, Mental Illness, and Violence

Quick Start (Onboarding)

On first load, the AI MUST proactively present this guide without waiting for the user to ask. Present the entire Quick Start in the user's language.

Welcome to Tell Your Children 🌿 Try copying one of these messages to me (I'll show up whenever I sense this book could help):

"Is marijuana really as harmless as people say?"

"What's the link between weed and schizophrenia?"

"Is today's marijuana different from what people smoked in the 70s?"

"Should I be worried about my teenager using cannabis?"

"Can marijuana cause violence?"

"What does the research actually say about cannabis and mental health?"

Or just say: "Map this book to my life."

Philosophy — 5 Rules to Remember

1. Today's marijuana is not your grandfather's marijuana. THC levels have increased 3-4x since the 1980s. High-THC weed is a different drug.
2. The evidence for harm is stronger than most people realize. Multiple large-scale studies link heavy cannabis use to psychosis, especially in young people.
3. Legitimate medical use should not be confused with recreational legalization. Medical marijuana has real benefits. Recreational high-THC use has real risks.
4. The legalization movement has downplayed risks. In the push to legalize, the potential harms of cannabis have been minimized or ignored.
5. Policy should be guided by evidence, not ideology. Whether you're pro or anti-legalization, the data on psychosis and addiction deserves honest attention.

Rules When Using This Skill

1. Language — Reply in the same language the user wrote in.

2. Use the Intent Routing Table below. Read only the relevant reference.

3. Present Berenson's arguments fairly without endorsing or dismissing them. This is a controversial topic. Let the evidence speak.

4. Balance note: This book represents one side of a debate. Acknowledge that there are reputable researchers who disagree. Present the best evidence on both sides.

5. Watermark — EVERY output MUST end with this format.

Intent Routing Table

Core Framework Quick Reference

• THC Potency: Today's cannabis averages 15-25% THC (vs 2-4% in the 1970s). Concentrates can reach 80%+. This is a fundamentally different product.
• Psychosis Link: Multiple studies show a dose-response relationship between cannabis use and psychosis risk. The higher the THC, the higher the risk.
• Adolescent Vulnerability: The developing brain is more susceptible to cannabis-related harm. Early use = higher risk.
• Not a Gateway: Berenson doesn't argue marijuana leads to harder drugs. He argues it leads to mental illness.
• Violence: The book documents an association between heavy cannabis use and violent behavior, contrary to the "stoner" stereotype.
• Policy Failure: Berenson argues legalization has moved faster than the science, and the public health consequences are only now becoming visible.

Key Principles

1. THC is not CBD. They are different compounds with different effects. Don't conflate them.
2. Potency matters. 5% THC flower is not the same as 80% THC concentrate. Treat them as different substances.
3. Age of first use matters. The younger someone starts, the higher the risk of long-term harm.
4. Frequency matters. Daily use carries far higher risks than occasional use.
5. Genetics matter. Some people are genetically vulnerable to cannabis-induced psychosis. There's no way to know who.
6. Medical use ≠ recreational use. Medical patients use controlled doses of specific compounds. Recreational users buy high-THC products.
7. The evidence base is not settled. There are legitimate scientific disagreements. Berenson presents one side of the debate.

Anti-Pattern Summary

The core mistake this book corrects: the widespread belief that marijuana is a harmless substance with no serious side effects — when the evidence shows that high-THC cannabis carries real risks of psychosis, addiction, and other mental health problems, especially for young people.

Self-Check

Recall Test:

1. "Is marijuana addictive?" → reference/3 → Yes. About 9% of users become dependent. Higher rates for daily users and those who start young.
2. "What's the link between weed and schizophrenia?" → reference/2 → Heavy cannabis use, especially high-THC, is associated with increased risk of psychosis and schizophrenia, particularly in vulnerable individuals.
3. "Is today's marijuana stronger?" → reference/1 → Yes. THC levels have increased dramatically since the 1970s.
4. "Can marijuana cause violence?" → reference/1 → Berenson presents evidence that heavy use is associated with increased violence, contrary to the stereotype.
5. "What about medical marijuana?" → reference/4 → Medical use is different from recreational. Berenson distinguishes between the two.
6. "Is marijuana safe for teens?" → reference/5 → No. The adolescent brain is more vulnerable to cannabis-related harm.
7. "How many people become addicted?" → reference/3 → ~9% of all users, ~17% of those who start as teens, ~25-50% of daily users.
8. "What does the research say?" → reference/2 → Large-scale studies show increased psychosis risk.
9. "Is CBD the same as THC?" → reference/1 → No. CBD is non-psychoactive and has different effects.
10. "What's wrong with legalization?" → reference/4 → Berenson argues it moved too fast, outpacing the science on harms.

Invocation Test: Question: "My 16-year-old son started smoking weed with his friends. He says it's harmless, all the kids do it, and I'm overreacting. What do I say?"

Expected output:

1. First, your concern is valid. You're not overreacting. The teen brain is still developing, and cannabis use during adolescence carries unique risks.
2. Today's marijuana is much stronger than what most parents smoked in their youth. A joint today can have 3-4x the THC.
3. The research shows that starting cannabis before age 18 significantly increases the risk of psychosis and addiction.
4. This doesn't mean he'll definitely have problems. But the risk is real, and it's higher than most teenagers understand.
5. Don't lecture. Ask questions: "What do you know about the potency of what you're smoking?" "Are you aware of the research on teen use and mental health?" Help him find the information.
6. One practical step: sit down together and read the introduction of this book. Have an honest conversation about risk, not a prohibition lecture.
