I smoked cannabis for nearly 20 years. Here’s what I wish I knew at 13. - The Washington Post

I can't create a detailed summary of this article because the content provided is incomplete—it cuts off after about 131 characters with the notation "[+131 chars]," meaning the actual body of the article isn't available to me.

Here's what I can responsibly offer:

What I can tell from the available material:

• The article is a Washington Post first-person opinion/essay piece titled "I smoked cannabis for nearly 20 years. Here's what I wish I knew at 13."
• The author describes beginning cannabis use as a teenager in Upstate New York, framing it as an emotional escape during their youth.
• The piece appears to argue that as cannabis becomes more socially accepted and legally available, the public should remain aware of possible long-term consequences of use—especially when it begins in adolescence.

Why I can't complete your request:

To write an accurate, fact-rich summary with the specific figures, names, and dates you're asking for, I'd need the full article text. Fabricating details (statistics, expert quotes, study findings, or specific claims the author makes) would violate journalistic standards and could mislead your readers—the opposite of Google Publisher Network compliance.

What would help:

If you can paste the complete article body, I'll gladly produce a 200–300 word, original-wording bullet summary that captures the key points, context, and implications while meeting the standards you've outlined.
