GCSE Core Science Human BiologyTask One

•A drug is any chemical that alters how our body works.

•Drugs that affect our CNS control the movement of chemicals across the synapse. These are called recreational recreational drugs eg hallucinogens

•The natural chemicals in our nervous system have shapes that fit like a key in a lock .

•Drugs have a similar shape to these chemicals and mimic (copy) what they do.

I know that all drugs cause problems whether they are legal or illegal
