Let’s see drinking all night, mix in smoking weed, perhaps hallucinating and staying up until the wee hours of the morning losing good sleep. Add in some deep water and presto. Maybe that was some really bad weed he smoked (like bath salts) and got him all whacked out.
At least the bath salts didn’t transform Rodney into a flesh-eating zombie that chews off the faces of naked homeless people.
Doubt it was bath salts. I learned back in my college days that if you smoke weed after you're drunk, the effect is like getting hit by a freight train. You're almost instantly incoherently trashed. This was 20 years ago. I haven't smoked weed in many, many years so I have no idea how potent the stuff is today, particularly in California where it is practically legal.
