Tl;dr at the bottom
I've been a smoker for years and about a year ago, I first noticed a change in how I react to nicotine. These changes have not only persisted to this day, they have also started occuring more frequently and become more intense. When I smoke a cigarette, I often get a euphoric rush with goosebumps all over my body and a more or less intense feeling of pleasure. Sometimes it's rather subtle, other times really intense. I never experienced this before late 2020. It all started when I began consuming sugar free energy drinks and diet soda (aspartame -> phenylalanine -> tyrosine?). I still get these effects without drinking those now, albeit not as strong.
According to various studies, nicotine upregulates tyrosine hydroxylase (tyrosine -> L-DOPA - rate limiting step in dopamine synthesis), activates the mesolimbic dopaminergic system (the reward center), limits dopamine transporter availability, causing a reuptake inhibiton like effect and enhances striatal dopamine release. For some reason, the dopaminergic effects I get from smoking cigarettes have become noticeably amplified. On the other hand, I can't even go a few hours without a smoke now without getting nicotine cravings/withdrawal symptoms comprised of massive brain fog, blurred vision, trouble concentrating, irritability and a weird sense of derealization. My brain doesn't function without it anymore. Could these changes be related to adaptive responses to my botox use/iatrogenic botulism somehow? Perhaps nAChR upregulation, modulation of voltage-gated ion channels, axonal sprouting, activation of the IGF-1 signaling pathway? Either way, gonna light one up now
Tl;dr: Smoker for years. A year ago, I started getting a dopamine rush with goosebumps and a strong sense of pleasure/euphoria when smoking. This reaction still occurs a year later and has become more frequent and intense over time. Can't go a few hours without smoking. Nicotine has many effects on the dopaminergic system. Trying to identify the biochemical mechanisms underlying these changes in my brain chemistry
