It's pretty clear now ... Scott Disick isn't concerned about drinking after his rehab sting -- he's lounging poolside with hot chicks down in Mexico.
Scott surfaced at Joe Francis' home in Punta Mita along with at least 5 babes in bikinis ... including one Kendall Jenner look-alike.
We'll say this ... at least he's hyrdating. Scott downed agua while taking some phone calls, but switched to cervezas when it was time to chill with the ladies.
Both go down well in the hot Mexican sun ... beer and water, that is.
