'Spice-Zombie' stumbles through traffic lights on busy road

A shocking video appears to show a 'Spice zombie' stumbling between fast flowing traffic before smacking his head on a barrier at a set of traffic lights.
The astonishing clip shows the young man - believed to be under the effects of the synthetic drug - blindly wandering along the busy road.
Filmed in Kilmarnock, East Ayrshire, the two clips posted on Twitter have received almost 7,000 retweets.
In the first clip, the man is filmed staggering down the street towards the traffic lights on the B7073 in the centre of the town.
A bus can clearly be seen slowing down as the apparently intoxicated man walks in the centre of the road towards the traffic lights. The person filming the clip says: 'What the f***?'
As the bus pulls alongside, the driver appears to look over at the man who is wearing grey jogging bottoms, a blue and grey top and carrying a blue plastic bag.
Spice is a mixture of smokeable herbs - shredded plant material - and man-made chemicals with mind-altering effects.
It is known as 'fake weed' or synthetic cannabis and has been wreaking havoc across the UK.
Its effects cause people to suffer severe psychotic episodes, terrifying hallucinations, vomiting and even seizures in public.
