The 26-year-old singer is expected to appear at a north London police station on February 2 pending analysis of substances and might be again charged with possession of drugs.
Last week Doherty appeared in court to face police charges on drug abuse. The rock star pleaded guilty for possession of heroin and cocaine after blood test confirmed the abuse.
Doherty has been in the headlines since his on-off girlfriend, Kate Moss was photographed snorting cocaine in his record studio and later charged herself with possession of class A and class C drugs.
