In Dallas, texas there is a difference between Chronic and kronic though they are both pronounced the same. (i have not heard this to be true anywhere but D-town)
Chronic
1.) One of the stronger strains of marijuana. It is actually NOT used to describe just any sort of good weed, there is a certain type, usually indica, that is labled Chronic. It won 3rd place at the 1994 High TimesCannabis Cup.
kronic
2.) Describing something that was awesome or really amazing. Especially a really good high.
