This episode goes on a road trip around the country to meet seriously ill people who believe cannabis is helping them. While it is seen as having no therapeutic value in the UK, in half of the USA's 50 states it has been legalised for medicinal use. Andy, Phil and others all believe that cannabis can - if not cure their condition - give them much-needed pain relief. The programme also meets Jeff, a cannabis campaigner distributing cannabis oil to the sick for free. But by resorting to this illegal and unregulated drug, what risks are they all taking?
