There's been a big improvement in the way most schools educate you about drugs, according to school inspectors.
Ofsted found that pupils had a much greater understanding of the dangers of drugs than when the system was last reviewed in 1997.
However, inspectors warned that some schools might be missing the mark, by focusing on illegal drugs rather than smoking and alcohol.
These were what kids themselves thought were the biggest risks to them.
Inspectors found that 80% of primary schools and 90% of secondaries now have a drugs education policy.
Their findings were based on visits to 60 schools and a further 200 school inspection reports.
Their report also said that most schools were against drug tests on pupils and bringing in sniffer dogs.
