Ecuador's Congress approved tougher penalties for small-time drug traffickers, an about-face from a more liberal policy which may have been prompted by the president's stated "zero tolerance" approach to heroin use. The new drug law will increase penalties for those caught trafficking small quantities of drugs, the Associated Press reported. The law follows a prior set of reforms approved by Ecuador's drug agency.
