No you can not.
Only if you kissed in a way to share cocaine that was in the persons mouth, which would be deliberate.
A casual kiss would not do this.
If you shared cocaine through kissing in sufficient quantaties, then you might test positive for a short period of time. 2 to 5 days.
OK, so that is an initial answer….

If the cocaine user recently ( 3 hours) ingested cocaine ( snorted) is there a possibility of failing a urine test if a person were to share drinks with the user. Is there a possibility that the users saliva concentration of cocaine is high enough for a person to fail a drug test?
Expert:  DrRussMD replied 1 year ago.
There is no documentation of that ever happening.
It will not provide an explanation.
Once again, enough cocaine would have to be put in the drink to cause a dose, and the test would have to be fairly rapidly done, within a couple of days.
There would have to be actual intoxicating doses of cocaine in the drink, and you would have known by your reaction.
