Snoop Dogg is in the middle of an international crisis, because he is accused of sparkin' a blunt in the middle of Lebanon, which ignited a criminal investigation. This according to a major Middle East concert promoter.

Snoop has been threatened with a lawsuit over an appearance he made in Beirut back in 2009, an appearance orchestrated by Middle East concert bigshot Roger Kalaouz.

Kalaouz claims Snoop blazed up in the middle of a concert after-party — which is illegal in Lebanon — and then featured footage of the puff session in a music video for his song, "That's Tha Homie".

Kalaouz claims Lebanese authorities caught wind of the weed smoking (no pun intended)– and launched a criminal investigation into his company, leaving his reputation "severely damaged."

Kalaouz claims Snoop also promised he could be the rapper's exclusive Middle East representative — but after Kalaouz started booking Snoop, his people told him the deal was never officially authorized.

Kalaouz has fired off letters to Snoop's people — demanding more than $280k in damages and a commitment for Snoop to perform 2 concerts in the Middle East.

Snoop's people told Kalaouz they were taking his complaint seriously — but so far, no agreement has been reached.
