Sherlock says "It's impossible to sustain a smoking habit in London these days. Bad news for brain work" and he uses nicotine patches instead. So why do you think John says "Shit" when Sherlock takes the cigarette Mycroft offers him after he identifies Irene's (fake) body? I'm sure Sherlock doesn't care for his lungs so as long as he gets nicotine to his brain, all's well. Why is the fact that him smoking an actual cigarette alarming to John & Mycroft? And, why must he use the patches anyway?

Sherlock uses the nicotine patches because most of the time he’s trying to quit smoking. In Hounds, it had been Sherlock’s idea to pay off everyone within a two-mile radius so they wouldn’t sell him any cigarettes. (Though he regretted it later when he wanted to smoke for lack of a case.)

The original character of Sherlock Holmes had a history of drug use. They haven’t directly stated it, but it’s been strongly implied that this version of Sherlock has a history of drug use as well.

Mycroft offering Sherlock a cigarette was evidently meant to be a test. When John spoke to Mycroft on the phone, he confirmed that it was a “danger night.” Then when Sherlock got home, he could tell John had been searching the flat (which he assumed included his sock drawer). I think the overall implication is that they were worried Sherlock’s accepting the cigarette was a sign that he might move on to other drugs.
