Cannabis is the most widely taken drug in the world, with approximately 144 million people having taken it. An illegal, class C drug in the UK, this book looks at the history of cannabis, and investigates what it is made from, and how it is taken. It also explores the effects of cannabis on the mind and body, from short-term effects such as impaired judgement and increased heartbeat, to long-term effects such as lung disease.
