As a Brit, I will admit that Miami in particular has always been presented to outsiders as historically repressing any overt establishment of a heroin scene in favour of the overabundance of cocaine and its culture, but regardless I have always found it difficult to believe that the trade does not exist, given the city's long legacy as a gateway port for all and sunder and the universal fact that there are few cities in the developed world that have not been touched by heroin. The quality of the crack is simultaneously unimaginable and unsurprising as I would expect that the overall standard of the coke has to be about as good as it gets outside of the actual Latin - American production and distribution zones.
Although much of the crack I encounter is generally of a decent standard, we are so far down the food chain here in the UK that the price of good quality powder coke has doubled in the past 15 years. compared to all other options for a twist, 50 pounds was always a luxurious stretch for an occasional purchase but with the same now costing a ton I doubt I will ever bother with it again domestically.
