Nepal's marijuana ban could soon be up in smoke, as lawmakers mull a return to the liberal drug policies that once made the Himalayan republic a popular pit stop on the overland "hippie trail". Half a century ago, thousands of fun-seeking backpackers from around the world made their way to Kathmandu to buy potent hash strains from government-licensed stores on "Freak Street" -- a lane named for long-haired and unkempt foreign visitors.

Washington's global war on drugs, and its accompanying pressure on foreign governments, prompted the closure of the capital's dispensaries in 1973, along with a cultivation ban that forced farmers to rip up their cannabis plants. Now, with Western countries easing their own prohibitions on marijuana, the government and legal reform campaigners say it is time to stop criminalising a potent cash crop with centuries-old ties to the country's culture and religious practices.
