The UK had the highest proportion of people who have bought drugs online out of countries surveyed for an international study on drug use.
A drugs baron nicknamed "The Craziest One" killed in a shoot-out by Mexican marines had been reported dead four years ago.
Police in the UK currently do not regularly test drivers for drugs - despite thousands of accidents each year being caused by high drivers.
Drugs education for children as young as 10 should be broadened, one of the Government's chief drug advisers has said.
Professor Simon Gibbons, a member of the Advisory Council on the Misuse of Drugs (ACMD), told a public hearing that more needs to be done on drugs education in primary and middle schools.
The subject of drugs does not form part of the National Curriculum at primary level, although it is at a school's discretion to include it within the teaching of personal, social, health and economic (PSHE) education.
Mr Gibbons, a professor of medicinal phytochemistry at University College London (UCL), said:
"I would certainly like to see more done on the education done in primary settings.
"I have two young daughters who are eight and 10 and the elder one is certainly at that age when she is starting to be aware of some of these materials.
"At the primary and middle school phase there's not enough information on drug education for 10, 11, 12-year-olds - that's something we should be pushing for."
The number of people who are injecting themselves with steroids or other image enhancing drugs is "rapidly increasing", health experts have warned.
More must be done to help the rising tide of people, including teenagers, who use these drugs, the National Institute for Health and Care Excellence (Nice) said.
Outreach programmes should be set up in gyms to try to reach this group of drug users, Nice said. They also warned that people who use steroids do not seem themselves as having a drug problem.
The health authority also said that needle and syringe programmes - which were set up in the 1980s and 1990s to stem the spread of HIV - should also make sure that these drug users have the sterile equipment they need to prevent the spread of blood-borne viruses.
Meanwhile, local health bodies need to increase the proportion of these drug users who are tested for HIV, hepatitis B and C and other viruses.

A shop owner has been convicted of selling items he knew would be used for drug taking in a landmark prosecution.
Hassan Abbas, 33, ran the Fantasia shop in Leeds which sold bongs, plastic bags and grinders all decorated with cannabis leaf designs.

Abbas was found guilty of supplying articles used to administer or prepare controlled drugs. He was fined £800.
Police used a mobile phone to finally track down drug lord Joaquin "Shorty" Guzman, officials have revealed.
The phone, belonging to one of Guzman's aides, provided key information as to the whereabouts of the cartel leader and led police to a beachfront flat where Guzman was hiding.
Officials also revealed that each of Guzman's houses they came across during his decade on the run had steel reinforced doors and an escape hatch below the bathtubs with each latch leading to a series of interconnected tunnels in the city's drainage system.
The United States will seek the extradition of Mexico's drug cartel kingpin Joaquin "Shorty" Guzman, officials said.
Federal prosecutors in New York plan to seek the extradition of Mexico's most wanted man, Guzman, who was captured on Saturday in Mexico with help from U.S. agencies, had long run Mexico's infamous Sinaloa Cartel.
The United States had placed a $5 million bounty on Guzman's head. His cartel has smuggled billions of dollars worth of cocaine, marijuana and methamphetamines into the United States, and fought vicious turf wars with other Mexican gangs
The US government applauded the arrest of Mexico's most wanted man, drugs kingpin Joaquin "Shorty" Guzman.
US Attorney General Eric Holder described the arrest as "a landmark achievement, and a victory for the citizens of both Mexico and the United States."
Guzman's cartel has smuggled billions of dollars worth of cocaine, marijuana and ethamphetamines into the United States, and fought vicious turf wars with other Mexican gangs.
"The criminal activity Guzman allegedly directed contributed to the death and destruction of millions of lives across the globe through drug addiction, violence, and corruption," Holder said in a statement.
Mexican authorities showed the world's most-wanted drug lord, Joaquin "Shorty" Guzman, to the public at Mexico City airport.
"Shorty" runs Mexico's infamous Sinaloa Cartel and is believed to command groups of hitmen from the US border into Central America.
