Edward Thornber, 17, played lacrosse for England and planned to teach it in the US, an inquest heard.
But he feared a court appearance would ruin his American dream after he was caught smoking cannabis on holiday in Newquay, Cornwall.
He originally accepted a warning, which would not mean a criminal record.
But his case was put in the wrong file by cops. They sent him a court summons, which should have gone to his parents because of his age.
Edwardâ€™s body was found at a park near his home in Didsbury, Manchester. The summons was found nearby.
Coroner Nigel Meadows said: â€œYoung people are particularly vulnerable.â€ Verdict: Suicide
Now this tragedy is merely a single anecdotal item and it can’t be fully laid at the feet of prohibition — the police screwed up, and young people are often susceptible to feeling things are hopeless when they are not.
However, this is an example, a data point, of millions of people whose lives have been ruined, or dramatically damaged, by the criminal prohibition of cannabis, even though they did not go to prison.
So when someone says to you “Why are you so concerned? Hardly anyone goes to prison for pot,” you should tell them about the people who lost their financial aid, their careers, their children, their possessions, or their lives due to criminal prohibition.
