I got a bit hung up on a detail , he said "I was a drug addict for 10 months." Before he got locked up I remember someone said he was on meth and Craig said "no, I hate tweakers." So I think he is trying to minimize his drug use and would rather he didn't have to admit he was a junkie, because it's below him as a man. But remember he was busted for dealing with MDMA earlier and "openly" used cocaine for years supposedly. And sure, maybe some can use drugs for a good amount of time without getting "addicted" per se. Opinions vary on this. Titus might still see himself as just a user at one time. In any case, "addiction" may speak to his favor, or maybe not. My assessment of the psychology involved lol.
Dante Doggcrapp said Titus asked him what he could take and still pass drug tests, and Dante said, basically just trenbolone as it was not looked for at the time. Titus said, fuck I can't be a pro bb on that. Then he failed his drug tests.
