It is being warned by drug agency, the European Monitoring Center for Drugs and Drug Addiction, of European Union that there could be serious health risks to people with new substances.

The addiction monitoring centre, reportedly, is responsible for informing governments about necessary evolution, context and influences. The group said that the fight against drug abuse was facing great challenges due to high youth unemployment and austerity budget cuts.

The annual report has been presented by the observatory in Lisbon recently, which included problems along with some hopeful solutions. These may comprise fewer heroin users as well as less taken by injection.

It was reported that the use of cocaine and cannabis had gone down in a few countries. Almost 50% of the 1.4 million opiate users in Europe were found to have been getting treatment. It is being said that the same was a positive sign, but the newly-developed, less-plant-based drugs were concerning. These, as per the report, had appeared because of continuous transformation of market by internet-selling.

The report finds that health structures face a huge burden by drug-users when they suffer from a health condition.

"The Internet presents growing challenges, both as a mechanism for rapid diffusion of new trends and as a burgeoning anonymous marketplace with global reach", said the center.
