Has anyone heard of Khat? (pronounced Cot) It is a plant from Africa - Ethopia and Somalia - it is legal in the UK and gives the user mild euphoria and is a bit like mild speed. It is legally available from Somalia type green grocers, probably maybe some in Blackburn or Manchester.
It comes in bundles of leaves on stalks and has to be chewed to get the effect - the juice from chewing is swallowed and the remaining material spat out. It is a lot of effort to chew it and has a bitter taste and is a bit similar to chewing a bag of liquorice - it takes up to 2 hours to chew enough. It is mainly used by those Ethnic types as a social stimulant in social meetings, bit like British use beer in the pub.
