Cigarettes will not make your brain release enough dopamine to get the dopamine high. Just enough to satisfy you temporarily after your addicted. The head rush comes from starving your brain of oxygen. That feeling only comes from your first few cigarettes. You will get used to it and it won't happen anymore after you become a regular smoker. If you're looking for another buzz for substitution or whatever, (I hate to say it but..) go with alcohol. Much more effective and safer than smoking. Just don't drive. If you're looking for one of the slowest and most painful ways to kill yourself, you're doing great! Keep chasing that dopamine high that ain't gonna come. But I beg of you quit while you're ahead. I've been smoking for 12 years now. I get nothing but stained teeth, bad breath, smelly clothes, empty pockets, bronchitis and headaches from it. It all started trying to get that lightheadedness or high from every cigarette.
