Mexican methamphetamine has a clearer, glassier appearance than more crudely produced formulas and often resembles ice fragments, usually with a clear or bluish-white color. It often has a smell people compare to ammonia, cat urine or even burning plastic. There was a time when the Mexican cartels had to import meth into Europe, but that is quickly becoming a thing of the past.
La Familia Michoacan/Los Caballeros Templarios cook in Africa (in five locations) and ship to France, Spain, The Netherlands and Great Britain. The Sinaloa Federation (El Mencho Faction) has done that one better by setting up clandestine laboratories in Europe to service the European market. France is home to some of the larger and more sophisticated cooking operations. I do understand that the French may be insulted by this revelation, but that doesn't change the fact that it's the case.
Having been to Interpol Headquarters (Lyon, France) as a guest on more than one occasion, I understand that France together with The Netherlands (Europol) hosts the international crime fighting efforts against such things. The Mexicans, with a substantial bankroll to back up their expansion, sought out the most corrupt and likely unemployed segment of French society to help them with both security and distribution. Yes, the French Muslim Community was and remains committed to the cause. The vast sea of unemployed inner city youths are both willing and able to help the Mexican drug cartels.
France has a well established, well trained, well paid, and highly professional police force. And if you ask them how all of the methamphetamine (90%+ purity) arrived in their nation, many would tell you that it's smuggled in. That may have been true once. Not so much these days.
The marketing format follows a well-established pattern. By simultaneously increasing the purity and cutting the price, the cartels get people hooked and create a new customer base. By including the locals in the profit making, they expand by forming alliances, taking advantage of existing distribution networks.
