A Somerset couple whose son was jailed for drugs offences say existing laws need radical reform.
James Humphreys was caught buying cannabis and ecstasy more than 20 years ago but his parents say he's still paying for his crime.
19 years old and a promising science student at Manchester University, James Humphreys was caught buying cannabis and ecstasy for himself and his housemates.
He was jailed for 2 and a half years in the notorious Strangeways Prison.
Despite graduating with a masters after his release, Mr Humphreys could not land his chosen job and now sells wood carvings on the roadside.
He declined to speak to ITV.
Mr Humphreys' parents have added their voices to the call for legalisation, and strict regulation of all drugs.
Bristol MP Thangam Debbonaire says there is growing evidence that demands a re-examination of existing laws.
Her call comes at the start of a week of action on drug policy reform.
A Home Office spokesperson says the Government has "no plans to decriminalise drugs".
"There is a substantial body of scientific and medical evidence to show that controlled drugs are harmful and can damage people's mental and physical health, and our wider communities.
"Drugs can have a devastating impact and this Government's approach to them remains clear - we must prevent drug use in our communities and support people through treatment and recovery.
"In July we released a comprehensive new drugs strategy, setting out a balanced approach which brings together police, health, community and global partners to tackle the illicit drug trade, protect the most vulnerable and help those with drug dependency to recover and turn their lives around."
