hi BBD. I suggest Chantix. It helped me quit smoking. I also quit using cocaine several years ago. So I know how hard it is. Both require the same level of committment. You gotta want to quit more than you want to use. Chantix helped me deal with the cravings for cigarettes. It didn't take them away 100% but it gave me the strength to say no when I felt like smoking. good luck.
