Originates from the vernacular of South Londoners, a synonym for "
drugs". Can be used with an adjective to specify the particular type of drug, e.g. Medium bits in relation to MDMA. Alternatively, a noun modifier
may be used to stipulate the type e.g. Cardboard bits for
Weed.
Those whose use the word "Bits" have also been known to exclaim the word "oi", with the tendency to prolongate the word in conversation.
