Narrative:

On a daily occurrence [adjacent ARTCC sector] hands us two or more aircraft that will lose separation within ten to fifteen miles within our airspace. Management is well aware of this and a lot of times when it's brought to their attention they shrug it off and snicker at it. There was a small area of precipitation just west of VOR ZZZ. Aircraft were deviating around it. [Adjacent ARTCC sector] handed us two aircraft on a collision course at 35;000 feet. The aircraft were to lose separation within 10 miles of our airspace. Both aircraft were deviating for the weather. The 4th line in aircraft Y's data block read [deviate left; then direct airport ZZZ] and aircraft Y's read [deviate left; then direct airport ZZZ1]. Either aircraft could turn back on course anytime they wanted without notification. Aircraft X could have turned right into aircraft Y! There was no positive separation insured by [adjacent ARTCC sector] controller! Noticing this the radar assist immediately called [adjacent ARTCC sector] controller to assign present headings to both aircraft. [Adjacent ARTCC sector] controller replied that he already shipped the aircraft! This is unbelievable! The transferring controller is to insure that all conflicts are resolved before transferring communication! This was not done! These aircraft could have collided within five miles of the boundary! This is blatant carelessness of the [adjacent ARTCC sector] controller!in my opinion [the adjacent ARTCC sector] takes separating aircraft a low priority. They have become lazy and complacent and is getting worse over the years. They are handing us dangerous situations to deal with on a daily basis! Unfortunately; it's going to take a serious accident or a collision of two airliners before this gets resolved!

Title: ARTCC Sector handed off two aircraft deviating for weather to adjacent ARTCC Sector. The two aircraft had clearance to return on course at their discretion which would have put them in confliction with each other. The reporter states it is a common occurrence to receive aircraft from this facility which will conflict with each other soon after entering their airspace.
