1987 federal sentencing guidelines is a pretty good reason
Five kilos of coke or more is a level 32
1000 kilos of ganj is a level 32
Back in the 80s a pound of weed was 50 US in Westmorelamd JA loaded and fetched 500-800 a pound by the ton consigned to a trustworthy wholesaler in say Rural Georgia or North Carolina
Not too shabby for identical risk
However smuggling weed North coast South America or JA or Belize north to SE USA coast or Gulf became untenable risk by 1990 in my opinion
Level 32 is ten years and as you know Feds are 54 days good time per year
85 percent to serve
Now Mexico owns the dope trade pretty much it seems
