A large amount of drugs are smuggled into Europe from Asia. The main source of these drugs is Afghanistan . Farmers in Afghanistan produce drugs which are smuggled into the West and central Asia. Iran is a main route for smugglers. The Border Police Chief of Iran says his country "is a strong barrier against the trafficking of illegal drugs to Caucasus, especially the Republic of Azerbaijan." 
Never before has the ground been more fertile for a fundamental shift in our nation's drug policies. See the victories our supporters made possible in 2016.

One further absurdity of the current approach is that it takes no notice of amount. This means that a single molecule of an “illegal” drug is illegal. This is already limiting PET research with new 5HT2A receptor tracers, where picogramme quantities required for tracer production (well below quantities having psychological effects) need licences [ 7 ]. Similarly, research on the epidemiology of new psychoactive substances is limited because once they are made illegal, transferring tiny (sub-active) amounts between research labs becomes subject to complex licence and import–export regulations. In the UK such licences are required for each and every drug separately which massively increases costs. Moreover each are time-limited to only 8 weeks so they need to be renewed repeatedly.
