Can breast implant removal be done with local anesthesia?

Hello doctor,

I am 35 years old. I am having breast implant explantation surgery in four days. I have bad anxiety and the thought of anesthesia really scares me. I am a mother and the thought of being over sedated or not waking up at all is frightening. My surgeon has agreed to use local and MAC anesthesia, because I did not want general. Can they give me just light sedation so I am not totally out? If my surgeon would have agreed to just do local with a pain pill I would have been on board. Unfortunately, he did not go for that. I do trust my surgeon, he placed my implants almost 10 years ago and now the left implant is deflated (I have saline implants). I am also worried as when they asked if I smoked I was only thinking of cigarettes and said no. Then I called and told them I do smoke Marijuana daily. They told me to stop five days before. But I am worried now since reading online that some prefer two weeks clean. Will this cause me to be at an even greater risk now?

Also, I have a minor cold and cough, no fever but coughing some sputum up. Nothing major and stopping smoking weed could be a contributing factor now. I do not smoke cigarettes or drink alcohol. I have a history of congenital cervical spinal fusion (two discs), TMJ, and anxiety, panic attacks. I exercise regularly and I am on no other prescribed medication besides Xanax 0.5 mg at bedtime which I only actually take a half tablet of when needed and that does the trick for me. I take an Emergen-C immune plus vitamin pack daily and a Stress-B complex daily (which they have not told me to stop). I am an RN and have been trying to rationalize and reassure myself that it is a common procedure and others older and in worse condition have surgeries all the time and are fine. My mind frame is so different than it was 10 years ago, where I easily trusted surgery and after augmentation was fine. I am praying daily that I will just be fine and I am over thinking everything too much. Any insight and thoughts would be wonderful.
