A minicab driver from Addison Lee, was secretly filmed inhaling crack cocaine as pedestrians passed by only inches away.
A shocked witness watched as he pulled kitchen foil from the boot, sprinkled on coke crystals and heated them from underneath.
He then used a makeshift tube to inhale the fumes.
The man described as Asian clean-shaven and aged about 30, leaned back as he felt the hit before driving off minutes later.
The Minicab filmed in Plastow East London, carried the Addison Lee livery on the roof and rear windscreen.
A spokesman from Addison Lee thanked the Sun on Sunday for drawing their attention to the video evidence.
He added "we have referred this matter to the police and transport for London. The driver has been suspended by Addison Lee and will no longer be providing his services.
