I had the same surprise some time ago, when i had a break... i thought it would be awful, but it wasnt.
Also, once a friend of mine said the mere act of grinding the weed and rolling a joint were enough for make him barely high... at that time i was a newbie and couldnt understand him, but now after some years it also happens with me... whenever i handle weed i feel slight relaxed, a bit calmer, and as if i were barely high... so the fact you handled weed may had helped also.
