article The amount of cocaine consumed by US adults has more than doubled in the past five years, according to new research published in the Lancet medical journal.
Researchers at the University of Pennsylvania, the University at Buffalo and other institutions analysed data from the Centers for Disease Control and Prevention’s National Survey on Drug Use and Health.
They found that there were 1.5 million adults aged 15 and over who reported using cocaine in 2013, up from 800,000 in 2007.
The number of people aged 25 to 34 who reported use of cocaine increased by 50 per cent between 2006 and 2013, from 3.6 million to 6.5 millions, the researchers found.
In terms of age, those aged 15 to 24 had the highest number of cocaine users in the US in 2013 at 3.5million, followed by adults aged 25-34 with 1.3 million.
This is despite the fact that young people were still less likely to be involved in drug use.
The researchers said this was because of the social stigma associated with drugs, as well as the fact most of the drug use was by younger people.
They concluded:”The rise in cocaine use among US adults is not explained by the fact there has been less stigma around drug use among adults.
Rather, the rise is due to the increased use of other illicit substances.”
Cocaine is a relatively new drug, which emerged in the 1980s and 1990s.
However, cocaine use has risen sharply in recent years as drug-related violence has increased in the country.
In 2015, the US had the fifth highest death rate for non-fatal cocaine overdoses among the world’s major economies.
Last year, the FBI reported that the number of Americans killed by cocaine was more than triple the rate in the UK.
The US Drug Enforcement Administration said last month that cocaine consumption was “on the rise” in the United States and that more than 80 per cent of the cocaine users are over the age of 50.
Dr James White, an expert on drugs and alcohol at the National Institutes of Health, said:”Drug abuse and drug addiction are both disorders of thought and behaviour.
They are related to the individual’s predisposition to drug use.”
Dr White said that while people who used cocaine had more of a negative outlook on life, it was “very likely” that cocaine use was linked to more serious problems such as mental health problems.
He added that more research was needed to understand the causes and consequences of cocaine use.
