Khat contains a stimulant cathionine which is similar to amphetamine. Chewing it can make people feel more alert but it can also cause insomnia, heart problems and feelings of anxiety and aggression. In June 2014 khat became a controlled class C drug in the UK.

Oxford ragwort, a non-native species, is thought to be a hybrid between two ragwort species, that occur in Sicily. This plant was brought from Mount Etna to Oxford Botanic Gardens, in England, in the 1700s, and from there it escaped into the surrounding countryside. With the expansion of the railway network in the mid 19th Century, Oxford ragwort, an attractive but rather invasive plant, soon spread along railway lines and can now be found throughout the UK. The clinker of the tracks provided a similar habitat to that found on the slopes of Mount Etna and trains helped to carry its parachuted seeds.
