Charlamagne Tha God has been hard on Drake over the years.

He's criticized the Canadian's music, his love of strippers, and also claimed he stole Big Sean's flow.

A few years ago, the radio host declared the era of Drake over.

Drake doesn't take criticism well.  According to CTG, Drake sent goons after him multiple times.

In fact, he learned from Drake's old security team -- who had since moved on to G-Eazy -- that Drizzy had put a permanent green light on him.

“I met these security guards one time at an iHeart music festival in Vegas," CTG said on the Rap Radar podcast.  These muthaf*ckas looked like killers. They were big super-goons. They were with G-Eazy at the time. And they was like, ‘Yo man, you know how many times we was told, if we see you, it's on sight? Don’t even ask no questions, just handle it?’ I’m like, ‘Really?’ And they’re like, ‘Yeah, we used to do security for Drake.'”
