---<br /> <br /> Charles Clarke has ordered a review of the Government's decision to <br /> downgrade cannabis after new research linked the drug to mental illness.<br /> <br /> He has written to the Advisory Council on the Misuse of Drugs and asked <br /> them to reassess their position.<br /> <br /> Last year cannabis was downgraded from Class B to Class C status after a <br /> recommendation by the Council.<br /> <br /> In his letter Mr Clarke pointed out that 'there is no indication from <br /> either the British Crime Survey or the more recent Schools Survey...that <br /> use of cannabis has increased.'<br /> <br /> However, he said, there have been several studies since which have looked <br /> at the links between taking cannabis and developing mental problems.<br /> <br /> One paper concluded that: 'Cannabis use moderately increases the risk of <br /> psychotic symptoms in young people but has a much stronger effect in those <br /> with evidence of predisposition for psychosis.'<br /> <br /> Mr Clarke said:<br /> <br /> "I think there is merit in the Advisory Council assessing whether <br /> their position is at all changed by the emerging evidence."<br /> <br /> He has also asked them to look into claims that there is an increased use <br /> in the UK of a high-strength cannabis known as 'skunk' which is causing <br /> concern to the Dutch Government.<br /> <br /> <br />Aurora Indica |  B52 |  Big Bud |  California Orange Bud |  Citral |  Four Way |  Haze |  Hindu Kush |  Indoor Mix |  Jock Horror |  K2 |  Maroc x Afghan |  Northern Light x Big Bud |  Northern Light x Haze |  Northern Light x Shiva |  Shiva |  Skunk #1 |  Skunk Red Hair |  Skunk Special |  Papaya |  White Rhino |  Haze 19 x Skunk |  Afghan |  Master Kush |  Northern Light |  Super Skunk |  Top 44 |  Durban Poison |  Early Bud |  Early Girl |  Early Misty |  Early Special |  Hawaii x Maui Waui |  Hawaii x Skunk #1 |  Hollands Hope |  KC 33 x Master Kush |  Mixed Sativa |  New Purple Power |  Swazi |  Swiss Miss |  Northern Bright |  Snow White (fem.) |  Supergirl |  Venus |  Wonder Woman |  Kaya |  PPP (fem.) |  Medusa |  Blue Mystic |  Chrystal |  Ice |  Misty |  PPP |  White Widow |  Nirvana Special |  White Rhino |  Snow White |  AK-48 |  Bubblelicious |  Silver Pearl |  Haze |  Jock Horror |  Northern Light x Haze |  White Rhino |  Haze 19 x Skunk |
