The science behind legal and illegal drugs - how they work, why people take them and what effect they have on us.

The dangers of illegal drugs are well known and rarely disputed, but how harmful are alcohol and tobacco by comparison?

The issue of what a drug is and how we should live with them affects us all: parents, teachers, users - anyone who has taken a painkiller or drunk a glass of wine. Written by renowned psychiatrist, Professor David Nutt, Drugs without the hot air casts a refreshingly honest light on drugs and answers crucial questions that are rarely ever disputed. What are we missing by banning medical research into magic mushrooms, LSD and cannabis? Can they be sources of valuable treatments? How can psychedelics treat depression?

Drugs without the hot air covers a wide range of topics, from addiction and whether addictive personalities exist to the role of cannabis in treating epilepsy, an overview on the opioid crisis, and an assessment of how harmful vaping is. This new expanded and revised second edition includes even more details on international policies, particularly in the US. David's research has won international support, reducing drug-related harm by introducing policies that are founded on scientific evidence. But there is still a lot to be done.

Accessibly written, this much-awaited second edition is an important book for everyone that brings us all up to date with the 'war of drugs'.
