The issue of cannabis always provokes strong reaction for audiences to Radio 1 and its urban music sister station 1Xtra.

It's certainly true that younger audiences have a more tolerant attitude to the drug than a succession of governments: they are, after all, much more likely to be users - but beyond that generalisation, the detail of the argument is fascinating and illuminating. That's why we're spending this week focusing on the arguments for and against the re-classification, as well as the health issues - myths and facts.

Rich from Wakefield texted 1Xtra to say he started on ganga when he was eight. But added: "Gave up for 2 years and started again, still smoking it and I'm fine." Over on Radio 1 another texter said: "I've been smoking green for 4 years now and I also know lots of people who have been smoking cannabis for 10 years...none of us has experienced any problems with our body and brain." Others contacted us to say that alcohol is far more harmful.

So our audience thinks it's harmless and are all for legalisation? Er, no.

On 1Xtra: "I think weed is pretty bad cos I was getting panic attacks and I cudnt even get on bus. My boyfriend has panic attacks 2." Others said they'd developed schizophrenia and depression, lost friends and split from partners because of their use.

Students claimed their studies and grades had been affected and that social lives had been damaged. Many blamed strong weed, skunk, for the problems. Memory loss, mood swings and loss of confidence were also blamed on green.

"I work in a homeless hostel and would say a quarter of our cannabis users have drug-induced psychosis. The other three-quarters suffer from depression which results in lack of motivation" (to work). Another user added: "I also had a friend who committed suicide due to paranoid schizophrenia which we believe was caused by cannabis."

But on the other hand back on 1Xtra: "I'm 25 I pay my rent, my bills, my child maintenance, if after a day at work I want 2 have a smoke I don't feel any1 is in a position to tell me otherwise."

So cannabis and schizophrenia. Is there a link? The government's top drug advisor, Professor David Nutt, told Newsbeat evidence is building to prove there is. But he reckons the risk is small - and alcohol can be just as damaging.

Marc Middlebrook, 27, was sentenced to life imprisonment last year for stabbing his girlfriend Stevie Barton to death because he believed she was part of a plot to kill him. The court heard that he had made his mental problems worse by "stubbornly" continuing to smoke cannabis after doctors told him to stop.

Newsbeat spoke to Stevie's mother Jackie, a former psychiatric nurse. She said she doesn't blame the drug for her daughter's death.

"I always say cannabis didn't kill my daughter, Marc did," she said. "I know lots of people - doctors, professionals, nurses - who have smoked cannabis for years and do not commit crimes." It's no good standing there wagging your finger and saying this is wrong. People need to be able to know the facts and there is a lot of information and counter-information around cannabis use at this time."
