Sheetal yes they do if you don't know, so much so that there is a place that is called mini Russia, they control drug deals upto a certain level, than there are Israelis who even use children as couriers and recently the very police who are being blamed for A to Z caught this children and a good quantity of drugs were found, different drugs at different level are being done by people of different countries and states, I would not like to waste time with the details as very few Goans are involved in drug trade its mostly controlled by foreign forces hand in glove with the law enforcers. Even the packaged tourist who come on chartered flights have been caught carrying drugs. Sure the very Safed Babus you think are Mr. Clean are the main drug suppliers.
