How early can gingival recession occur from using Snus tobacco?

I just recently started using the new smokeless tobacco product Snus. I have heard that it can cause gingival recession. I am not a consistent user. I use about two packets a day about 3-4 days a week. Sometimes I do not even use all week. How early can gingival recession occur? Please let me know. I use tobacco as a stress-reliever, having a huge amount of stress in my life. Please be serious about the answers, I will report any inappropriate answers. Thank you very much.
