Any proof that high officials of this country has something to do with drug cartel? Probably few, there is. But yeah, I agree with you, drug problem cannot just be solved in a year or even in many years, and yeah, most of the drugs here are brought by foreigners, probably there is a connivance between few officials.

The last time I hear a news about it here in the locality, the chinese already escaped and left their  kilos of illegal drugs in their laboratory before the raiding team arrive.
