With Goa increasingly becoming a hot spot for drug abuse, the involvement of tourists is evident from the fact that nearly half of the people arrested in narcotics cases were foreigners.

Police sources said that many of them who died were found to be drug addicts. Last year, the death toll was 59. And 55 foreigners died in in 2007.

The police records reveals that in half of the cases, the cause of death is unknown sans the viscera report.

In 2008, the number of such cases sent for chemical analysis of viscera is 6 out of 12.

"The viscera report basically establishes whether there is presence of drugs in the stomach or is it poison. Depending on it, section 302 of IPC (murder) can be invoked in these cases," a senior police officer said.

"Visit any rave party and you will find hoard of foreigners inhaling drugs. The coastal belt is getting increasingly ruined with the drug rackets," a police officer said.

The Goa police website lends an insight into foreigner's link with drug cartels in the state. The anti-narcotic cell has found almost 50 per cent of its drug accused as foreign tourists.
