The hip-hop superstar previously revealed he had been anointed Snoop Lion by a Rastafarian priest after experiencing a spiritual awakening while recording his first reggae project, Reincarnated.
He adopted the traditional dress and dreadlocked hair during his time in Jamaica and filmed his transformation for a documentary, also titled Reincarnated.
But Wailer is not convinced by Snoop's new lifestyle and he has accused the rapper of the "outright fraudulent use of (the) Rastafari community's personalities and symbolism".
Members of the Rastafari Millennium Council have also launched a verbal attack on Snoop, demanding he refrain from using the moniker Snoop Lion and apologise for his behaviour - or face legal action, according to Tmz.com.
They have also fired off a seven-page letter to the marijuana-loving star, insisting that "smoking weed and loving Bob Marley and reggae music is not what defines the Rastafari Indigenous Culture".
