(England) Cannabis is a Class C drug Primary school pupils are being told to pretend they are smoking joints at a party and dealing acid and ecstasy in controversial new drugs education classes. Several hundred schools across the country have bought teaching packs which invite pupils to imagine taking a range of illicit narcotics in a series of role-plays. Children as young as nine are required to assume the part of drug-dealers while seven-year-olds can act out drinking alcohol at a cousin's wedding. However, in an embarrassing blunder, 30 copies of the lessons in booklet form have been targeted at children much younger than intended. Activities in which children pretend to be partying with drug-dealers and getting tipsy at a wedding have been stamped as suitable for infants aged five to seven instead of seven to nine-year-olds. The publishers insist the error will be corrected. Furious parents last night said the lesson packs, previously available as CD-Roms but now relaunched as booklets, were not suitable even for older children. They warned they were too lurid for their intended audience of junior school pupils and could backfire by encouraging early experimentation with illegal drugs. The teaching materials introduce pupils to drugs jargon such as "fix", "spliff", "hyping up" and "cutting" substances with other drugs. However the creators of the products insisted role-playing was an effective way of helping children to resist drugs. They pointed out the scenarios are designed to show the harmful effects of drug-taking. The character who takes acid ends up in hospital with injuries serious enough to ruin his promising football career. At least 250 copies of the "Drugs Centre Stage" CD-Rom are circulating in schools in areas including Kent, North Yorkshire, Somerset, Nottinghamshire and Tyne and Wear. Meanwhile 30 copies of two booklets, which use much of the same material as the CD-Rom, have been bought up by local education authorities since their launch in June. The first of the booklets, aimed at seven to nine-year-olds, includes a story explaining what it feels like to get drunk. Cousin Susan's Big Wedding features guests enjoying themselves at a reception, with Uncle Alex doing a chicken dance. It then tells how a young guest takes a glass of an alcoholic drink during a toast to the bride and groom to fit in with everyone else. Pupils are told: "After quite a few sips, you start to feel funny. You can't stop yourself from giggling. The music gets in your head and you dance around and around and around." For another activity, teachers are told: "Ask the class to think of types of parties where drugs, alcohol or tobacco might be involved or come up in conversation: such as a drug-dealers' party...." The second booklet is meant to be targeted at nine to 11-year-olds but was printed as suitable for pupils in "key stage two" - seven to 11. It features boys sitting in a circle at a party, passing a joint around. Characters are also offered acid and Es, with one saying to her friend: "I had an E a couple of weeks back. It really hypes you up, and it didn't do me any harm." In one scene featuring a heroin addict, one of the lines reads: "I think Gary's OD'd. He's not moved for a week and he's starting to smell." The publications last night raised renewed concern over the quality of drugs education materials being used in classrooms around the country. Current Government policy is not to prescribe lesson plans for drugs awareness lessons, instead leaving it up to schools. Schools must only ensure the materials follow broad guidance which stipulates that pupils know which drugs are legal and illegal and their effects and risks. Norman Wells, director of the think-tank Family and Youth Concern, said: "Most parents will be appalled at the thought of their primary school-aged children taking part in role-plays in which they are required to act out antisocial behaviour that is quite alien to their experience. "This approach trivialises what is a serious social issue and runs the very real risk that such vivid and premature exposure to the effects of drug-taking may arouse an unhealthy curiosity in some children and encourage experimentation. "Primary schools would do far better to place a much stronger emphasis on positive role models." The materials were produced by playwright Chris Scanlan, who worked with Kent County Council drugs advisers. He said 10 copies of the CD-Rom were subsequently bought by the authority. Mr Scanlan said: "I know not every teacher will want to use all the information but it is there if they want it. "Children as young as 11 are known to deal drugs. They are certainly not unaware of what goes on." Margaret Morrissey, spokeswoman for the National Confederation of Parent Teacher Associations, said children should be given straight-forward messages that taking drugs is harmful without first acting out drugs-related scenarios. "Drugs education like this under-estimates the intelligence of children and gives them a taster of what it is like to do what we don't want them to do" she said. "We don't tell children to pretend to smoke packets of cigarettes before telling them they should not have cigarettes."
