Although the '90s were all about 'heroin chic', it seems like the current decade has actually seen the biggest rise in heroin deaths in the past 20 years, increasing by 37% between 2010-2013. The rise is attributed to multiple factors—heroin is cheaper and stronger than ever before. Even more fascinating is that some are saying that the crackdown on prescription drug abuse has probably pushed addicts towards heroin. Also consider that since the aughts, heroin-growing areas like Afghanistan, Thailand and Mexico have had a fair share of instability, both politically and socially, and trade with China has only increased in the past 15 years, likely opening up new avenues for drug trafficking.
