A national survey of 15-year-olds found that 19% living in Richmond had tried the drug. This is the second highest rate in England – the highest is 24% in Brighton.
Across London, 27% of 15-year-olds say that they have been offered cannabis, in line with the national rate. A little over 1 in 10 say that they have tried smoking the drug but rates are higher in 13 boroughs.
Richmond stands out as having the highest rates, and as reported by Urbs, also has the highest proportion of teenagers drinking alcohol and getting drunk. 16% of 15 year-olds in Lambeth and Islington say they have tried cannabis, with 15% in Camden, Haringey, Lewisham and Wandsworth.
Rates are much lower in the east of the capital. Just 6% in Tower Hamlets and Redbridge, 7% in Newham and 8% in Barking and Dagenham, and Havering.
The data from the What About YOUth survey reveals that young people from a mixed ethnic background are most likely to have been offered and tried cannabis. Those from Asian backgrounds are least likely. 93% say they have never smoked the drug, according to the survey, compared to 89% of all 15-year-olds.
Richmond also has the highest rates for teenagers who say they have smoked cannabis in the last year (17%) and in the last month (8.5%).
The survey offered little evidence of a link between cannabis and other drugs. Just 3% of 15-year-olds in London say that they have tried other drugs, though rates are between 5-6% in Bromley, Haringey and Camden.
