A number of customers said they had been left shaken by the experience.

UBER customers have claimed their drivers are offering them drugs with concerns flagged that the taxi system is the "ideal means" to sell illegal products.

Dozens of people have reported the dodgy dealings, with many taking to social media to recount the drug offers.

One man took to social media just days ago, writing: "I've had Uber drivers offer me sex or/and drugs before", adding they had been concerned about the driver talking about assaulting their previous fare.

Others flagged that the offers became "aggressive".

One Twitter user wrote: "Had a bulls*** experience with Uber last night and I'm still kinda shaken.

"Driver tried to push drugs onto me and got aggressive".

Clapton local James Newman told The Times that he had been offered cannabis by his Uber Eats deliveryman.

He said: "After the food transaction he attempted to close a second deal.

"He sized me up and then asked whether I wanted to buy some weed."

His experience was shared by a number of other people on social media with one man writing in October: "We got an Uber back last night and the dude was like "Ya I Uber drugs to parties a lot of the time, you want some blow?"

The Sun Online has not been able to verify these incidents.

Josh Klein, a technologist interested in commerce, black market economies and Big Data told Vice: "You have a massive drug market which requires extralegal delivery mechanisms and a widespread, independently operated network of drivers for whom it is an ideal means of masking their activities."
