my tongue seems weird.sometimes it looks like my tongue has this white stuff on it and like 2 -3 tiny red dots

I have never even kissed a girl before---so it's nothing sexually related ...but yesterday I did smoke weed, and I shared a pipe to smoke it with my friend. First of all is this related to sharing the pipe with him as our saliva came in contact most likely? I am a bit of a hypocondriac so often times I try to convince myself that I have something when most often I don't. Also up until about 3 weeks I had always brushed my teeth once a day...but in the last 3 weeks I have been brushing anywhere between 2-5 times a day. Is my tongue irritated from the additional brushing all of sudden or is it related to sharing the pipe? There's no way this could be herpes is there? I mean would herpes show up after only a day? If it's not herpes what is it....open up your own mouths, and look closely and tell me if there are tiny red dots---not many just check if you have them, cuz then I'll know that's supposed to be there.
