Not really a question but i quit smoking 1 month ago and i smoked 1 cig tonight?

i gave the pack to a friend, after not smoking for so long you can actually taste the cig and it tasted pretty bad. It wasnt what i thought, i thought i was going to enjoy it because ive been craving them but i didnt i hated it so i think i should be ok. Hopefully i can continue on my quitting. I also feel high and now i have a headache.
