Bit dubious about the excuses from this *81* year old man (now Britain's oldest drug driver!) nicked for #DUI and testing positive for #cocaine - someone of that age who got spiked would likely keel over if they didn't have tolerance, and even other #drug users generally aren't so malicious to give a dose without consent to a senior on his birthday!
I doubt the old bill would have just put the marker on his car as a mistake either (and such markers can be added just for users as well as dealers)
He's probably been getting away with it for a while, but got grassed up somewhere along the line, maybe should take it on the chin and count himself lucky he's not got caught for anything worse and landed up in the senior wing of HMP!
