Cigarette changing question?

Okay, so, I recently started smoking Marlboro Reds and I don't mind the taste. I've been smoking for maybe 3 days now, 1 or 2 a day. Today, I bought a pack of Camel Crushes. My question, can I change my brand of cigarettes or will it be a bad idea to blend the two? And please don't tell me smoking all together is a bad idea. I'm just asking a question.
