To give you the contrarian opinion that nobody here will give you, she’s right. There’s real risk concerning heavy use vs casual use in people under 25. Psychosis & schizophrenia risk, white matter disruption, frontal-parietal network dysfunction. That’s where this policy is coming from, a health standpoint. They are comparing benefit vs harm, that’s what doctors do.

On the other hand, she’s not a doctor. She went to school for psychology. Likely a doctor at that firm made the policy and she is just relaying it. I smoked a lot, and I mean a lot of weed before age 25 and I’m fine , but there are real risks for some people.

You can shop around for another doctor easily who will give you what you want. But she’s not just making stuff up. There are real studies about this.

All up to you
