It's odd how different types of alcohol affects drinkers differently.I don't ever recall being affected by nicotine in any tobacco I've smoked....be it cigarettes,cigars or pipe tobacco. I'm not saying that to make out as being tough I'm not. I suspect it's because I've been smoking for 50 years since I was 15 and my body got used to it.
Alcohol is a different story....doesn't take much to get me giddy.
It was not unusual for me, in my wilder days, to drink an entire bottle of bourbon at a party and I could still walk a straight line.
Too many beers on the other hand made me a dopey drunk.
At 14yo a mate & I often went into town to buy exotic foreign cigarettes like Gitanes, Sobranie, Camel non-filter just to name a few, and can't recall ever being overly affected by nicotine.
Since ditching a 30-40 cigarette addiction for a pipe, I choose blends with no more than mild Vit N.
When I smoke a bowl of anything a little stronger nicotine wise I notice it.
Whether that sensitivity is a matter of age [61yo] or tolerance I couldn't say.
