The government will decide next week whether to outlaw the drug Khat which is popular with London's Somali community.
On 11 January the Netherlands announced it was to ban the drug.
Khat is a plant grown in Africa and campaigners against the herbal high say it can cause mental health problems.
BBC London Home Affairs correspondent Guy Smith meets the men who import the drug and those that use it.
